Why Tankless?

Tue, 11 Feb 2020 15:45:20 GMT

Why Install Tankless Water Heaters?

Unlike Europe and Asia, where tankless on-demand waterheaters are common, in the USA storage type units are prevalent. This type of technology is well developed, understood by most homeowners, but really quite wasteful. In today's world more people are making an effort to preserve our natural resources and conserve energy. Conventional tank type heaters are throw way appliances and their carcasses are clogging landfills nationwide.

USA Water Heater History

The traditional residential whole house gas model tank type heater dates to 1894. The first model with 90% efficiency was produced in Kalamazoo, Michigan by a company named Humphrey. Today's tank models are only about 75% efficient. The reason is because of simple economics. The older models were made of "Monel" which was a copper-nickel alloy. Many of these that were produced in the 1940s and '50s are still in use today. These days, the primary concern for consumers and contractors is simply the lowest possible price. To be competitive in today's marketplace, tank type heaters are made from very thin metal with a glass coating. Essentially, we accept new heaters that are 20% less efficient than those of 100 years ago. The average American household spends $400 to $600 per year for water heating, making water heating the second highest energy expenditure behind furnace and air conditioner operation.

Today, after 100 years without change, North Americans are beginning to accept new water heater technology. The technology that is familiar to families in Europe, Asia, Central and South America seems new to the average American homeowner. In fact, this technology is now considered "mature".

Tankless Water Heaters

In comparison to conventional tank heaters, tankless models differ in the fact that they do not have a large water storage tank. In theory, on demand type instantaneous water heaters should be the best way to go since there is no energy wasted by heating a large tank of water for indefinite periods of time. These models supply instant hot water in a continuous supply as needed. Sensors turn on the instant heater when a hot water tap is opened, and the unit turns off when the faucet or shower head is closed and the flow of hot water stops.

No Storage = No Shortage

Tankless water heaters are capable of supplying more hot water than a tank water heater which has a stored total capacity. Exceed this capacity of stored hot water and you need to wait for another tank to heat. Depending on your model and type of tank type heater, this can take several hours. On demand means there is no energy being wasted re-heating a tank of hot water. On demand means never worrying about running out of hot water. Imagine the luxury of always having enough hot water for your showers, your hot tub and still have an endless supply of hot water for the rest of your household needs. For large homes or small businesses with greater GPM needs, tankless heaters can be joined together and work simultaneously to supply larger volumes of hot water.

A few words about water flow in gallons per minute (GPM). Tankless water heater manufacturers speak in gallons per minute, tank type manufactures speak in total gallons held in reserve in the tank. For example, a tank type heater may hold 40 gallons of hot water and a tankless heater may be capable of producing a maximum constant flow of hot water at 3.2 gallons per minute. Comparing a 3.2 Gpm tankless water heater to a 40 gallon tank type heater is in fact an interesting thing. At the flow rate of 3.2 gallons per minute, a 40 gallon tank type heater will run out of hot water in 12.5 minutes. Our 3.2 Gpm EZ Deluxe tankless heater will still be providing hot water at the same flow rate long after the 40 gallon tank heater is running cold.

In a tankless type heater, the water is heated as it passes through the unit so you will never have to use hot water that has been stored in an old rusty tank. As the years pass, a conventional tank-type water heater begins to accumulate rust and build-up scale inside the tank, which is where your hot water is being stored for use.

Tankless water heaters can be installed virtually anywhere. Compared to traditional water heaters, the most obvious difference is its small size. Our tankless water heaters mount on the wall, inside or outside.

In comparison, conventional gas water heaters use a draft method of exhaust. This exhaust method relies upon natural suction to draw out the gasses though a flue. These gasses contain carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide, formaldehyde, respirable particulates and other harmful bi-products of combustion. These combustion products may result in eye, nose, and throat irritation; fatigue; dizziness; and nausea. With an indoor on demand tankless heater using a sealed forced air exhaust, these potentially harmful gasses are evacuated from the home through the sealed stainless steel exhaust system.

The Myth

Years ago, early tankless heaters could not keep up with the demands of the typical American household and they often broke down. For this reason, they have acquired a reputation for premature failure and inadequate supply. In reality, today's models are a lot more dependable and can keep up with any household's needs if the unit being installed is properly sized. Today's tankless heaters are designed to last 15 to 25 years or more.

As with any type of water heater, the primary enemy of a tankless heater is hard and/or sediment heavy incoming water. All tankless heaters work best when used with a water softener and/or a filtered incoming water supply. As with any type of water heater, periodic flushing and internal cleaning is recommended.

Gas or Electric?

Electric facts: Typically, electric models are used for single sink, or half bath type installations. Or for use in a workshop or cabin.* When in operation, larger whole house electric models can easily consume more electricity than the usage demands of the entire house combined. For this reason, gas models are preferred for whole house multiple bath installations. (If an adequate supply of electricity is available, whole home units can be used. - Typically, these units require 100 to 150 amps of 220V electricity on two or three independent circuit breakers with special stand-alone wiring. Some older and small rural homes are still operating on a "60 amp service." Obviously, the home would need a service upgrade just to power the electric tankless heater.)

Please note: Some small electric units that look like a tankless water heater are actually not. They are tank-type heaters in disguise. These models typically hold about 2.5 gallons of water and this water is constantly kept hot by an electric heating element. In reality, this type of unit is very inefficient. After the 2.5 gallons of hot water is used, it takes quite some time to reheat another tank full. These work for occasional hand washing and can supply less than 2 minutes of hot water.

Bathroom Additions

If you add another bathroom near the garage, a Direct Vent tankless heater can be installed on a garage wall with a short run of plumbing to serve this area. This way, no extensive plumbing modifications or updates to your existing water system are necessary. Your original heater may remain in operation as before and still meet the needs of the remainder of the home.

Small Business

If you operate a small service station, repair shop, store or cafe, the hot water for the restrooms can be supplied by a small tankless unit mounted on an interior wall in the utility room or storage space. This way, the restroom sinks have an independent and reliable supply of hot water and there is no worry about tampering of the unit. A small tankless unit can easily meet the needs of two restrooms that have no showering facilities. In this scenario, there will be a large savings in gas consumption and removing a large tank type heater will eliminate the open flame pilot light and can add additional floor space to the utility room.

Information for "Remote" Users

A lake or deep-woods cabin, campsite, workshop or outbuilding is perfect for the installation of a tankless type water heater. In rural America it is common for a homeowner to have a barn, workshop or tool shed that is some distance from the home. If cold water is plumbed to this building, a tankless unit can supply hot water for showering, cooking, washing vehicles, hand washing, and general cleaning needs. You may wish to install the unit near the sink and in this case a small unit will be perfect and economical to purchase. You may wish to use one that is fired by LP gas and a small tank can be easily installed for this purpose and may easily last the whole season or longer. Just like your outdoor barbeque, you must remember to turn off the gas valve after each use to insure that the LP does not leak away. Some people have large LP tanks for the furnace in the workshop and/or rural home. We have models for this type of gas. Additionally, in a workshop or garage installation there is no open pilot light to worry about.

In fact, we have customers with remote mountain cabins and campsites who are using our EZ-101 model with a small LP tank. Some are getting their water from a gravity feed system via a holding tank or down hill gravity fed delivery system. Some are using gasoline powered pumps to pick-up mountain stream or spring water and deliver it to the cabin via hose or plastic pipe. Our customers never cease to amaze us with their diverse and innovative ways to supply their remote locations with easy hot water for cooking, cleaning, and showering.

(With all water systems used in colder climates, if your outbuilding is not heated, you must address the possibility of freezing temperatures and drain the water system thoroughly each fall.)

NOTE: We have an interesting article about venting and freezing.

*LEGAL DISCLAIMER: We at EZTANKLESS.COM do not make spectacular claims about energy savings, our intention is to provide accurate and all-inclusive information for those who wish to gain a better understanding of this water heating technology. Certainly, a tankless heater is more energy efficient than a large tank type heater, but simple common sense tells us that the way in which each household uses hot water makes calculating actual individual savings virtually impossible. For these reasons, we assume no responsibility or liability for errors or omissions regarding statistics or statements. As with all conservation studies, the figures are only estimates, actual results will vary and may be lower or higher depending on the ways in which these products are used.

Certainly, there are companies making claims that are outrageous and spectacular. Certainly there are companies who will tell you how much you "will" or "can" save. Statements that say "as much as" are no more than hypothetical best case scenarios used to "boast their wares." We certainly accept no liability for assumptions of spectacular claims from other entities being projected onto our products or assumptions that these outside claims apply to anything that our company sells.

Persons researching tankless heaters should take the time to compare the technical specifications of the products in mind. Those which are similar but have much higher claims of savings, efficiency, or faster payback periods must be considered suspect.

Furthermore, all of the above information is based on documents and information that can be easily found within the public domain. We have organized this information on this web page for the convenience of our potential clients and those who have been looking for answers./p>

NOTE: If you are considering a purchase of a tankless water heater with the intention of taking advantage of the tax credits, please consult your accountant or inspect in detail the terms and requirements of federal tax credits. Some of this is unclear at the time of this writing as this was entirely new legislation enacted to take effect in early 2009, some of which has not been thoroughly clarified.

We cannot be held responsible for errors or misinterpreted conclusions from any of the above information.

Conventional Heaters

Tue, 11 Feb 2020 15:38:29 GMT

Why Not A Conventional Water Heater?

In today's world more people are making an effort to preserve our natural resources and conserve energy. Conventional tank type heaters are throw way appliances and their carcasses are clogging landfills nationwide.

The average American household spends $400 to $600 per year for water heating, making water heating the second highest energy expenditure behind furnace and air conditioner operation.

Save up to 50% energy usage with a tankless water heater

When you talk about going Green and helping the environment why not save a little money in the process. Instant Tankless Water Heaters can save the average American family $108 a year (source: U.S. Department of Energy). Consider that hot water accounts for 30 percent of an average home's energy budget.

Tankless water heaters provide an instant continuous flow of hot water as needed by utilizing a heat exchange coil and water flow switch, eliminating the standby energy loss of a conventional storage tank water heater.

The U.S. Department of Energy stated that a gas fired tankless water heater is about 23 percent more efficient that a traditional storage version, which is constantly heating your water 24 hours, 7 days a week. This constant heating of water is called standby energy loss.

Small Cars and Tankless Water Heaters - A Comparison

Tue, 11 Feb 2020 15:35:44 GMT

We are trying to "think green" and many of us are buying products that consume less energy. Are economy automobiles and tankless water heaters similar?

The ways in which consumers select them are similar and the answer is often "yes".

Why?

We are thinking of tankless heaters in respect to the fact that they use substantially less energy simply because they only use energy when they are making hot water. As tankless water heaters are sized by their abilities to raise the temperature of water and send it out of the heater in a specified gallons per minute capacity (Or liters per minute) they are a different concept than the typical tank type heater. Once a person determines the gallons per minute (GPM) that are needed for an application, a tankless heater can be selected. Tankless heaters come in many sizes and different types of design and construction.

Selecting a tankless heater is in some ways similar to buying a new car. Many people are looking at small cars because they consume less fuel for each mile driven. Maybe they are trading-in the "gas guzzler"? But certainly most people realize that they are reducing the size and power when they switch to a small car? For example; when one wants a car that gets tremendous miles per gallon, typically they have a very small engine and the car itself is also very small. As the horsepower and size are enlarged, then the economy goes down. This is the trade-off. Certainly one cannot expect a small inexpensive economy car to have comforts, space and performance of a much larger automobile. When one purchases an economy car they should realize that most are intended for commuting to and from work. When operating a small economy car while driving alone, the performance may in fact be impressive, but as passengers and materials are loaded into the interior, the weight increases and the performance rapidly drops. If a person takes the family and all their travelling necessities on vacation and expects to drive this little car across the continent in comfort, they are often disappointed.

The same basic rules apply to tankless heaters. Smaller ones can work well, but when they are tested to their capacity they sometimes disappoint the user. But this is the same for a tank-type heater as well. For example, a 40 gallon tank-type heater holds that water in reserve pre-heated. If a person uses three showers at once and each shower-head consumes 2 GPM, then there is a 6 GPM draw on the tank-type heater.. The math is simple, that big 40 gallon tank of water will be expended in only six and one half minutes! And you may have thought that your current 40 gallon heater was big! But use two showers and there is only a 4 GPM draw and the supply will last ten minutes. A 4 GPM tankless heater may in fact run two showers, but this depends upon the ground water temperature. As the way in which tankless heaters are sized also depends on how many degrees in "temperature rise" the heater must achieve. People who live in Northern climates (especially in the winter) receive less GPM from a tankless heater than those who live in Southern climates.

This is the way it is, but many may not realize that this rule applies to tank-type heaters as well. Even though a tank type heater must recover the full tank of water and reheat it to the desired temperature which takes time. The fact is that like a tankless heater, this older tank-type technology also changes the temperature from the incoming ground water and raises it to the pre-set desired temperature. And again, there is that same calculation of temperature rise. So, this means that people in Southern climates can expect that their tank-type heater will recover faster than those who live in the North. This is the reality and there is nothing that can change it. For this reason, the ground water temperature is a constant variable that must be considered for those who are shopping for any type of water heater.

What about this temperature rise thing, why is it important?

All manufacturers specify the capacity of their tankless heaters in GPMs with a specific temperature rise. Most companies use the "45 degree rise" calculation which makes the GPM number much higher. But the reality is that typical ground water temperature in the middle of the continent is 55 degrees. A 45 degree rise will only deliver 100 degree water to the user. As 105 degrees is considered comfortable for showering and 120 degrees is the typical desired temperature of users in North America. A 45 degree rise is usually insufficient. A 70 degree rise is more realistic but with this calculation the GPM capacity will be reduced substantially. (This is the reason that we have placed temperature rise and GPM charts on our website.)

What does all this really mean when I am shopping for a heater?

Once again we can take a lesson from the automobile manufacturers. A typical economy car may have a combined rating of 38 MPG city/highway. But we know that real world users rarely see numbers this high. Since this variable is industry wide, it can be assumed that all cars and trucks actually get lower miles per gallon than specified which makes things relatively equal.

If a person wants to buy a less expensive economy model tankless heater that produces GPMs close to the needs of the user, then it can be assumed that there will be times when the capacity is exceeded by unexpected demands or that it simply does not perform in the ways in which the buyer visualized. If an economy car is driven in the way in which it was designed and for the purpose intended, this economy car delivers the desired results. But it is not a large car capable of hauling large loads and delivering higher performance. After all, it is an "economy" car and it should be driven in an economical way. If a consumer really needs a large car because of passenger and load needs or wants high performance, then buying a small "econobox" car will only lead to occasional or possibly frequent disappointment. These same basic rules apply to any type of water heater, tank or tankless.

Elsewhere on our website we explain in detail the ways in which to select a model to fit your specific needs. We explain in detail how to measure the GPM needs, what are the parameters of installation and typical municipal, state and federal rules and regulations.

Gentle Carousel - Helping Those in Need

Tue, 11 Feb 2020 15:31:18 GMT

Several weeks ago we had the pleasure of talking to a Mr. Jorge Garcia-Bengochea. He came to us asking if we would be able to offer a tankless water heater for use by his charity service - Gentle Carousel.

Gentle Carousel brings miniature therapy horses to hospitals, assisted living programs, hospice programs, programs for Alzheimer patients and to adults and children with disabilities so that they may experience a little extra joy in their life. The miniature horses of Gentle Carousel will visit upto 4000 adults and children every year.

After hearing of the good work Mr. Garcia-Bengochea is doing, we were glad to offer a helping hand. We sent the Gentle Carousel an EZ 202 for use in their horse washing station. This is the card we received in response.

We would like to thank Mr. Garcia-Bengochea for allowing us this oppurtunity to help with his cause.

From all of us at EZ Tankless, Inc.

Gas-Fired or Electric. What is Best for My Needs?

Tue, 11 Feb 2020 15:27:42 GMT

Every day someone contacts our company asking us for an electric tankless water heater. What we notice is one common misconception. Almost everyone inquiring about an electric tankless heater wants to install it as a replacement for an existing electric tank-type water heater. We have found that most people are visualizing that they simply mount the new electric tankless heater on the wall and plug it into the pre-existing wiring from their old tank type heater. This is simply not a correct assumption. For an electric tankless heater to supply hot water at the required GPM (Gallons Per Minute), a much larger amount of electricity is required. The amount of electricity required is huge when compared to typical appliances. In fact, an electric tankless hot water heater’s electricity requirements exceed the capacity of the typical American home. To find out the details, please read this report and comparison. We have taken the time to explain these energy consumption needs in an easy to understand way.

Early in our research, we extensively evaluated electric tankless water heater technology and chose to focus our efforts on gas-fired models. We decided that our company would not enter into the business of electric tankless heaters for a number of reasons. Without turning this article into a sales pitch, we will point out some of the same facts that resulted in our company’s selection of gas fired heaters as our product line.

Simply comparing our popular EZ DELUXE 4.0 GPM model to a similar but slightly smaller GPM capacity electric unit, one can clearly see the differences. (To be fair, we compare our EZ Deluxe to one slightly smaller and one slightly larger electric powered unit. The manufacturer’s specifications of the models used in this comparison are listed on their web site and we presume that they are accurate. However, we did not conduct tests on the specific electric models used in this specification comparison.)

As previously mentioned, please keep in mind that not everyone lives in a modern newer home, older homes typically do not have 200-AMP and larger electrical services and modern expandable circuit breaker panels. In fact a 300-AMP service is rare in a residential application. Some older homes have only 100-AMP services and in fact some small rural homes may still be operating on 60-AMP services which were typical before the days of central air conditioning and multiple baths.

OUR EZ DELUXE TANKLESS HOT WATER HEATER

Our 25 KW (85,000 Btu) EZ DELUXE gas fired tankless heater is rated at 4.0 GPM (at a 60 degree temperature rise. If the ground water temperature is the typical 55 degrees, this means that the maximum exit temperature will be 115 degrees at 4.0 GPM.) The EZ DELUXE requires only a simple 115-volt plug-in for the control-panel and fan motor that operates the direct vent system. It is fused for a maximum “overload” current draw of 115V 2-amps.

WE COMPARE OUR EZ-DELUXE TO A WELL KNOWN ELECTRIC TANKLESS HOT WATER HEATER

For this comparison, we selected two Stiebel brand “Tempra” electric tankless hot water heaters. The first example is a 24 Kw electric model that is rated at 3.3 GPM (Rated by the manufacturer at a 50-degree temperature rise. This means that if the ground water temperature is 55 degrees, the maximum exit temperature at 3.3 GPM will be 105 degrees) Ten degrees lower than our EZ Deluxe model

The manufacturer specifies a 300-amp minimum service. (Size and capacity of the user’s electrical panel) A supply of 240-volt electricity at 100-amps, and installation of two 60-amp circuit breakers with two runs of #6 copper wire.

NOTE: Even on a 300-amp service panel, this is no small load.

This same manufacturer offers a 36 Kw model rated at 4.9 GPM (Again it is rated by the manufacturer at a 50-degree rise with a typical exit water temperature of 105 degrees). To achieve this 4.9 gallon rating the manufacturer specifies 150-amps of 240-volt electricity, three 60-amp breakers and three runs of #6 copper wire. Certainly in many older homes, electrical service upgrades would be required before these units could be installed. At what expense, we cannot determine. Some upgrades may be relatively inexpensive, some may be more elaborate and the costs can be substantial.

COMPARING (ONE RUN) OF 240V - #6 WIRE TO A TYPICAL EXTENSION CORD

WHAT DOES THIS REALLY MEAN?

Another way to explain the electrical requirements of an electric tankless model is to visualize how much electricity is required in comparison to appliances that are more familiar to the average home owner. For example: The 36Kw electric tankless model that delivers 4.9GPM at a 50 degree rise is using 36,000 Watts.

36Kw is approximately the same amount of electricity required to run 30 coffee makers. All of them turned on at the same time.
36Kw is approximately the same amount of electricity as required to simultaneously run 60 average sized microwave ovens turned on the high cook setting.
Or maybe you are familiar with the 5,000 BTU window type air conditioners. (The one-room variety that sell for about $150.00 in the big chain stores) Imagine that you could run 36 to 45 of these air conditioners simultaneously to equal the current draw of this one electric tankless water heater.
36Kw is approximately the same amount of electricity required to run a Toyota Prius! This same 4.9 GPM electric thankless water heater is rated at 36Kw 240V and a 2001~03 Toyota Prius has a 273.6V motor that is rated at 33Kw.

HOW DO I KNOW THIS IS THE TRUTH?

We suggest that you do your own research and we believe that you will draw similar conclusions. Certainly there are applications for electric models and they work and people use them in their homes. Electric tankless heaters do save energy. Every tankless water heater saves energy as they only use energy when a hot water faucet is turned-on. Gas or electric models have no standby energy consumption and are therefore more energy efficient.

We know from experience that there are some homes that are best served by a gas-fired appliance. We feel that the vast majority of our present and future customers are best served by our specialized knowledge of gas models. We did this comparison to show that gas-fired tankless hot water heaters are more easily adaptable for the most number of users who typically are making a transition from a tank type heater. In fact, 99% of our customers are buying their first tankless water heater as a replacement for a tank type unit and may not completely understand the numerous differences in the technology and related energy requirements. For this reason, we feel it is in our best interests to concentrate on supplying our present and potential clients with one of the most informative and unbiased web sites on the net. We know we can’t sell a hot water heater to every person that contacts us or browses our website, but we are proud to be leaders in offering the American home owners up to date and easy to understand information.

For more information about how to select the proper size of tankless heater and the requirements of exhaust and intake air, please see our additional articles related to these subjects.

See our faqs page for everything you ever wanted to know about tankless heaters and then some.

Thank you for your interest in our products and we hope that we have helped you make an informed decision on selecting what type of tankless heater best fits your specific needs.

Things to Consider Before Purchasing Your Tankless Water Heater

Tue, 11 Feb 2020 15:22:21 GMT

Recent studies show that 20% of energy consumed in a typical American home is from water heating demand. Switching to a tankless water heating system is proven to provide energy savings, lowering energy bills and reducing your carbon footprint. Many homes demonstrate energy cost savings of $150 per year on average.

Proper Installation -

We recommend you contact your local licensed plumber who is trained to handle electrical, gas, and plumbing and is aware of all gas fuel codes for a proper installation of the EZ Tankless water heater. Having a non-licensed professional install the unit can cause performance and operational issues.

Location of Installation -

Install on essentially any wall inside your home with our sleek and modern design. EZ Tankless offers a unit for every location.

Venting -

EZ Tankless offer the most economical and easiest to install systems on the market and we include the standard intake/exhaust components at no additional charge. Our tankless water heaters can vent vertically through the roof or horizontally through an exterior wall depending on the model.

Gas Line Sizes and Fuel Types -

EZ Tankless water heaters are designed to provide maximum performance and are available for natural gas or liquid or propane fuel types. The units operate using 1/2" or 3/4" gas line depending on BTU rating. Most of our homes units require 3/4” gas line.

When choosing the model that suits your needs the best, ask these questions:

Will I run out of hot water?
Where can I install my hot water heater? Exterior wall? Interior wall? Central location?
Do I have natural gas or propane?

Are American Consumers Really Trying to Reduce Energy Consumption?

Tue, 11 Feb 2020 15:20:25 GMT

Americans consume, it is what they do!

Are American consumers really trying to reduce energy consumption, or is this just another false start like the oil crises' of the 1970s?

We have all heard about the "American consumer". Why Americans are called "consumers" is simply because they consume everything they can find, and typically in a very big way. After all, consuming is the "American Way" and this includes oil, electricity, water, and natural gas. Often they consume in ways that are in fact shameful. But Americans don't care, they can consume as much as they want and nobody can do anything about that. It is the right to consume that drives the American economy. Or is it? With the $4.00 per gallon gasoline prices of 2008, Americans were suddenly dumping their big cars and SUVs and in a few months they had purchased millions of little automobiles with small fuel efficient engines. With a typical American knee-jerk reaction to high gasoline prices, Americans are buying these same little cars that people the world over have been using for decades. For more than half a century Europeans and Asians accept these same small cars as they have dense cities with not much available parking space and traditionally pay two or three times as much for gasoline than drivers in the USA. In late 2008 the U.S. Government instituted the "cash for clunkers" bill which paid new car buyers a discount at the dealership up to $4500.00 if they traded-in their gas guzzler for an economy model. This was designed to help the struggling auto industry and reduce the need for imported oil.

So, what else is new on the energy saving subject? Tankless water heaters! The typical American will ask; what is a tankless water heater? Another way in which Americans waste energy is the ways in which they heat hot water. As usual, Americans have procrastinated until they are the last culture on earth to change their wasteful ways. Fifty years after Europe began to use tankless hot water heaters this technology has finally entered the minds of some American homeowners. After 100 years without change, Americans are slowly beginning to accept new energy efficient water heater technology. For America, today's flavor of the month is to "go green". This and a substantial tax credit for "green" devices are driving the rapidly expanding USA market for eco-friendly tankless water heaters.

The large storage tank type water heater in the typical USA home is a big user of energy. The average American household spends $400 to $600 per year for water heating, making water heating the second highest energy expenditure behind furnace and air conditioner operation. Like the $4.00 per gallon gasoline prices of 2008, it seems that only a slap in the face can awaken the typical American from their wasteful ways. Again the U.S. Government steps in to stimulate (pay) Americans to reduce their energy consumption. This tax credit incentive took effect in February of 2009 and offered a substantial Federal Income tax credit to get the attention of the public and news media alike.

USA WATER HEATER HISTORY

Unlike Europe and Asia, where tankless on-demand water heaters are common, in the USA storage type units are prevalent. The storage tank type water heater is well developed, understood by most homeowners, but really quite wasteful. Conventional tank type heaters are throw away appliances and their carcasses are clogging landfills and lying in roadside ditches across North America.

In the USA, the traditional residential whole house gas model tank type heater dates to 1894. The first model with 90% efficiency was produced in Kalamazoo, Michigan by a company named Humphrey. Today's tank models are only about 75% efficient. The reason is because of simple economics. The older models were made of "Monel" which was a copper-nickel alloy. Many of these that were produced in the 1940s and '50s are still in use today. For many years, the primary concern for USA consumers and contractors was simply the lowest possible price. To be competitive in the marketplace, today's tank type heaters are made from very thin metal with a glass coating. Some of them have external insulation wraps as well. Essentially, Americans accept new heaters that are 20% less efficient than those of 100 years ago. The bottom line is that tank type heaters keep large quantities of water at a specified temperature 24/7 and this wastes energy. Imagine how much energy is expended nationwide to keep all of those tanks of hot water at a constant temperature? It is almost incomprehensible how much energy could be saved if every USA household had a water heater that only used energy when a hot water faucet or shower was actually turned on.

TANKLESS WATER HEATERS

In comparison to conventional tank heaters, tankless models differ in the fact that they do not have a large water storage tank. These models supply instant hot water in a continuous supply as needed. Sensors turn on the instant heater when a hot water tap is opened, and the unit turns off when the faucet or shower head control is closed and the flow of hot water stops.

Tankless water heaters are rated by the GPM of hot water that can be supplied. (U.S. Gallons Per Minute) If properly sized, they are capable of supplying more hot water than a tank water heater which has a stored total capacity. Tank type water heaters are rated in U.S. Gallons by their total capacity of stored hot water. Exceed this capacity of stored hot water and you need to wait for another tank to heat. Depending on the model and type of tank type heater, this can take several hours. For large homes or small businesses with greater GPM needs, tankless heaters can be joined together and work simultaneously to supply larger volumes of hot water.

Tankless water heaters can be installed virtually anywhere. Compared to traditional water heaters, the most obvious differences is its small size. The typical tankless water heater mounts on the wall, inside or outside.

Tankless heaters require a different concept in exhaust. Because they use a forced air duct system that has higher temperatures, stainless steel pipe designed for this purpose is an essential part of any installation of an indoor model. This special forced air exhaust pipe is unique to this technology and has sealed joints. (On this type of exhaust, the gasses are forced outside under pressure.) In comparison, conventional gas water heaters use a draft method of exhaust. This exhaust method relies upon natural suction to draw out the gasses though a flue. These gasses contain carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide, formaldehyde, particulates and other harmful bi-products of combustion. These combustion products may result in eye, nose, and throat irritation; fatigue; dizziness; and nausea. With an indoor on demand tankless heater using a sealed forced air exhaust, these potentially harmful gasses are evacuated from the home through the sealed stainless steel exhaust system.

GAS OR ELECTRIC?

Typically, electric models are best for single sink, or half bath type installations, Or for use in a workshop hand sink or small cabin. When in operation, larger whole house electric models can easily consume more electricity than the usage demands of the entire house combined. In fact, some electric models tankless heaters may be larger than the supplied maximum service of the home. For example, many small older rural homes still have the original 60 amp service which was common many years ago. Obviously an 80 amp heater will not work on a home with 60 amp service. Homes built in the 1960s or 1970s may have 100 amp services and again an electric whole home tankless unit is going to consume a large portion of the home's electrical supply. For this reason, most experts agree that gas fired models are best for most whole-house multipl-bath installations and this is the reason our company does not sell electric models of tankless heaters.

THE MYTH

As usual, American consumers perpetuate and exaggerate the negative. They believe the negative rumors of the past and as usual, most people are not to be bothered with finding out the real truth. With the internet, up to date and accurate information about tankless technology is easily found. It seems that internet based tankless information is the driving force of this new market. Even today, the typical USA home improvement store has employees without tankless training. Even though they sell tankless heaters, their personnel typically know very little about them. Years ago, early tankless heaters could not keep up with the large demands of the typical American household and because of this they often broke down. For this reason, they have acquired a reputation for premature failure and inadequate supply. In reality, today's models are a lot more dependable and can keep up with any household's needs. (If the unit being installed is properly sized in GPM capacity.) Today's tankless heaters are designed to last 15 to 25 years or more and just as American consumers have been reluctant to give up their gas guzzling autos and SUVs it may take a generation before the majority of Americans truly believe in the same tankless technology that is accepted worldwide.

Modern Gas Fired Tankless Water Heaters

Tue, 11 Feb 2020 15:17:54 GMT

So maybe you have a flex-fuel or Gasoline-Electric hybrid vehicle in your driveway, maybe a compost pile in your back yard? You’ve insulated the house, installed the thermal-pane windows, and may even have a newer energy efficient furnace. Now that you are warm and cozy and “feeling the green” are you still heating a big tank of hot water 24/7/365? If it is a gas tank type heater, did you know that not only are you wasting gas by heating hot water constantly, but you are drawing heat from your home via the draft type exhaust pipe. Maybe you need a tankless hot water heater to complete your green home?

“A gas-fired tankless water heater, what is that? Please tell me more?”

In Europe and Asia tankless water heaters are the norm. In the United States, homeowners are more familiar with tank storage type water heaters. Today more and more families are making an effort to conserve energy and preserve our natural resources by switching to tankless technology.

Primarily, tankless models differ from the typical large cylindrical heaters because they have no storage tank. On demand type, instantaneous tankless water heaters are better as no energy is wasted by pre-heating and holding a large quantity of water in reserve for future use. Tankless heaters produce almost instantaneous hot water in a continuous supply on demand.

“How does a tankless heater work?”

Sensors inside the heater detect that a hot water tap (faucet or shower) has been turned-on and the heater begins to run, making hot water that exits the heater into the hot water pipes leading to the faucet, sink, or shower. When the faucet or shower is turned off, the heater shuts down and the flow of hot water stops. Modern gas-fired tankless heaters don’t even have a pilot light! They have automatic electronic ignition to save even more energy.

“So they save energy. Are they better than a tank-type water heater in other ways?”

Tankless heaters can supply a larger total volume of hot water than a tank water heater. The reason is that a tank type heater has only a certain total capacity available. Tank type heaters are sized by their reserve hot water capacity in gallons. Typically only 30, 40 or 50 gallons of water is stored and if you exceed this capacity you must wait for another full tank to heat which can take several hours on some models. With a tankless heater, you have an endless supply of hot water for your needs. The way in which a tankless heater is sized is by its capacity to provide hot water at a specific GPM. In the USA, the volume of water flow is measured in GPM (Gallons per Minute)

When a large volume of hot water is needed, more than one tankless heater can be joined together in a group and work in unison. For a tankless heater, the important thing to remember is how to properly size the tankless heater unit to the needs of the household or business in question by calculating your maximum peak GPM needs.

“Please tell me more about GPM and how to properly size a tankless heater?”

As previously mentioned, tankless water heater manufacturers size their heaters via GPM specifications. Often this is also included with fine print about the temperature rise. If your groundwater temperature is 45 degrees, and the manufacturer advertises that the heater can supply a temperature rise of 60 degrees at 4.0 GPM. What this means is that the output temperature of the water coming from the heater will be 105 degrees at a maximum flow of 4.0 Gallons Per minute. Tank type heaters are sold as total gallons held in reserve in the tank. For example, a typical tank type heater may hold forty gallons of water. Comparing a 4.0 GPM tankless water heater to a forty gallon tank type heater is possible. For example, if a tankless unit produces hot water at 4.0 gallons per minute, this rate of flow will run a 40 gallon tank type heater out of water in only ten minutes.

“Please tell me about the latest evolution of tankless water heaters. Because several years ago, I was told they were not very good.”

It is a fact that the early models of tankless heaters sold in the USA years ago were small and could not meet the needs of a typical household. (Especially the electric ones.) They were primitive and often broke down. Sometimes the homeowner had to wait for a visit by a qualified technician and then parts were needed and had to be ordered. Because of these experiences of years past, tankless heaters had developed a reputation for malfunctions and an inadequate supply of hot water. Today’s models are designed to last fifteen to twenty-five years, and are much more reliable. If the unit being installed is properly sized to meet the needs of the home or business, and properly maintained, it will supply reliable continuous hot water for many years to come.

“Is there a down-side to a tankless water heater?”

The biggest enemy of any water heating device is hard or sediment filled incoming water. (For example, as you may have experienced, this is the leading cause of failure in coffee makers) As with any type of water heater, the tankless varieties also work best when used with a water softener or at the very least a filter installed on the incoming water supply. Just like a tank type heater, manufacturers of tankless models recommend diligence in performing periodic flushing and internal cleaning as recommended. The interval period for this maintenance depends on the hardness of the water and the type of filtering and/or treatment being done to the incoming water. Learn more about properly maintaining a tankless water heater.

In addition, households with well water will need to address the need for a more constant water pressure. Well pumps cause fluctuations in pressure that can confuse the internal control devices of a modern tankless heater. Find out more about using a tankless water heater with well water.

“I have been told that the exhaust for a tankless water heater is special. Is this true?”

The exhaust on a tankless heater is much different. Most of today's models use forced-air ventilation or are direct vent. (Direct vent is also known as "balanced" or "dual chamber" exhaust-intake) Because of much higher exhaust temperatures, stainless steel pipe designed for this purpose is always used. This is an important part of any indoor installation and is a requirement of industrial, local and national safety codes. This type of pipe has special sealed joints. This pipe is not the same as normal water heater or furnace exhaust pipe and the components do not interchange. With this type of exhaust the gasses are forced outside under pressure, not by a natural updraft as in a tank type heater.

American homeowners are now accepting tankless water heaters as the wave of the future. The average American homeowner is just now finding out about this technology when in fact, people in other countries around the world know of no other way to heat water.

“If I buy one now, will it be obsolete in only a few years?”

More than ninety percent of the manufacturers of tankless water heaters are based in Asia. These heaters are built in modern new factories operated by companies that have been building millions of tankless heaters for decades.

At this time, it is our understanding that there are no gas-fired tankless heaters produced in North America

This is not new technology, it seems new to the typical USA homeowner because we are just now becoming aware of how much energy they save. These days, as a society we are beginning to change our wasteful ways and try to save energy. But as a homeowner, we are not only trying to save energy, but to also reduce our energy expenses as well. These new modern direct vent tankless water heaters have evolved to the point where the USA federal government has declared this technology "mature". What this means is that little future change is expected in these devices. They have reached a level of development where they are about as energy efficient as they can be and the design seems to have peaked as well. In fact, generally speaking most direct-vent heaters from all manufacturers are basically the same design.

And in fact, some of the big-box home improvement chain stores are selling tankless water heaters under several different brand names that are in fact identical and produced in the same Asian factories. For some popular models, only the labels, brand names, and retail outlets differ.

A Brief Movie Explaining How to Flush Your Tankless Water Heater

Tue, 11 Feb 2020 15:11:56 GMT

Mike from EZ Tankless discusses how to flush your tankless water heater with the help of service valves.

Flushing your tankless water heater is the most important maintenance practice for keeping your tankless water heater in running order. Flushing your heater can expand its lifespan by many years, and in some cases can help your heater to last a lifetime.

In this video we demonstrate how to flush your tankless water heater with the help of tankless water heater service valves. These valves are available from our website, your local major hardware store, or you can build them yourself. You can flush your heater without the use of a valve set but it will require disconnecting water to your unit, which in some cases can be more of a burden then the extra money for the service valves.

Tankless Water Heater Installation on Well Water System

Tue, 11 Feb 2020 15:08:11 GMT

WARNING! Keep in mind that well pumps are 220 volt. The combination of water, metallic surfaces and electricity can be very dangerous if not understood and/or respected to the utmost level of safety. Well water pump systems have all three of these components and are complicated devices. There is substantial risk of electrical shock and/or serious injury.

NEVER work on a well pump switch without disconnecting the power supply.

DO NOT TAKE UNNECESSARY RISKS.

It is ALWAYS BEST to ask a professional to make these adjustments for you.

The Problem:

The most common question we receive from tankless water heater users on well water systems is fluctuating temperature when using their hot water. This is usually in an eight to ten degree temperature range which is most noticeable when taking a shower. After many hours of research and testing in our Indiana facility with an actual well water system, the EZ Tankless technical team believes that they have solved this common problem for most persons using a tankless water heater on a well and pump water delivery system.

The Causes and the components explained:

If you are using a well water system, you more than likely have an electric well pump. This pump has a low end ("ON" switch) and high end ("OFF" switch). The average home owner will usually have a 30psi/50psi or 40psi/60psi well pump switch. This switch works in unison with your pressure tank.

An explanation of the operation of the pressure tank. Most older systems have a small pressure tank and most newer systems have a much larger tank. What this tank does is to regulate the water pressure during the cycles of the well pump. Inside the tank is a large rubber diaphragm which presses against the water in the lower portion of the tank to achieve a more consistent water pressure supply for the user. This is not an exact science and the pressure tank has a limited ability to control pressure at a precise level. Newer large pressure-tank systems are more effective but the vast majority of well users have older systems. Above the centrally located flexible rubber diaphragm is compressed air which gives the diaphragm its force that applies the downward pressure to the water in the lower half of the tank. (Typically there is a small bicycle type schrader valve on the top of the tank for checking the air pressure and refilling as necessary.) If the pressure tank is in good condition, the water in the lower half never comes into contact with the air in the top half. As it is "just there" and has no electrical connection or electric switches, this tank will last a very long time. Consequently, this is usually the most neglected component in any older well system. As these tanks age, the diaphragm can fail or the air pressure may not be correct. Most homeowners never think to check the air supply above the diaphragm, or to inspect the tank until a problem arises.

Additional notes: Typically there is a large information sticker on the pressure tank itself. On this sticker will be the tank size, model information, and the correct air pressure requirement. Use a bicycle tire gauge to check this pressure. Be aware that too much pressure can cause the diaphragm to fail or even cause the tank to burst. Especially if is is old and corroded. An old tank may also have corrosion and sediment inside, so occasionally replacing this item is not a bad idea and should be considered. If you are switching to a tankless water heater, it is a good idea to address every component in your well system at that time. This is a good opportunity to bring the system up to date. Place a new larger pressure tank into the system, have the pump and switch professionally serviced, and enjoy the improvements.

An explanation of the operation of the well pump pressure switch. When you open a faucet or turn on the shower on a well system, your water pressure immediately begins to drop and continues to drop until it hits the low-end setting on your pump motor switch, then the pump kicks-on and rapidly brings the pressure back up until it hits the high-end on your switch and the pump turns-off. (If you connect a water pressure gauge to your water line you can easily see this fluctuation. The rise in pressure is rapid and depends upon the GPM capacity of the pump itself, and the fall in water pressure depends upon the amount of water flowing from an open faucet or shower head.)

Even when the pressure tank is operating correctly there can be a constant fluctuation of pressure as the pump cycles. This pressure change due to the pump cycling is the reason for the fluctuation in temperature you are experiencing with your tankless water heater.

Why does a modern tankless heater have this fluctuation? The reason that this is happening is simple. No matter what brand of tankless heater, modern ones with temperature controlled hot water use sensors and switches to regulate the burner and fan motor to supply consistent hot water at your desired pre-set temperature. This works well when the tankless heater is connected to a water supply with consistent pressure. (Typical municipal systems have a constant 45 to 65 psi delivered to the home.) When the system is subjected to rapidly rising and falling pressure, the tankless heater is trying to supply the selected hot water temperature, but in reality it is "chasing" the constantly changing pressure. As the pressure rapidly rises when the well pump starts, the heater control system senses this and turns-up the burner to compensate. No sooner than the heater adjusts itself to this rising pressure, the pump turns-off and the pressure begins to fall until the pump turns on again and the cycle repeats itself. The heater never catches up to the pressure changes because the water pressure never stops changing. This racing to keep up with this constantly changing pressure is why the temperature is fluctuating.

The SOLUTION:

You can do a combination of two relatively simple things.

You can purchase a water pressure regulator. A water pressure regulator will keep the water at a constant pressure, thus eliminating the temperature fluctuation.
Increase the low-end setting on your pump switch to decrease the range of pressure fluctuation.

Using a water pressure regulator as the solution. In our tests in our Indiana facility, we reduced an eight to ten degree temperature fluctuation to one to two degrees with this simple installation of a pressure regulator and no modification of the pump switch settings.

Pump settings explained. You will want the low-end setting of your pump switch to be slightly less than or equal to the setting on the water pressure regulator, this will keep your water pressure at a consistent level. Simply place the regulator in-line on the inlet (cold side) of the water system near the entry point to the home. (Or at what point you wish to regulate your hot and cold mixture for reasons of comfort) You may wish to mount the regulator near the tankless heater.

For example, if your pump has a 40/60 switch (40psi is the low-side of the pressure). Set the regulator to 40 psi and there will be a constant supply of 40 psi water going into the water system and the tankless heater. Or change the switch to 50/60 range and then set the regulator at 50psi etc... Keep in mind that when the pump switch range is adjusted in this way, the pump will run in shorter cycles. With this "regulator" solution, the heater will no longer be chasing after a constantly changing pressure and will supply a consistent temperature.

IMPORTANT NOTE about locating the regulator and its use: Please realize that if you are only regulating the water going directly into the tankless heater, the cold side of your shower will still have a well pump related pressure fluctuation. In this scenario, you may actually correct the problem of the heater "chasing" the pressure changes but continue to have a shower temperature "comfort related" temperature fluctuation due to the cold side variations. This is caused by your "mix" or blend of hot and cold changing on the cold side via pressure fluctuation caused by the well pump switch cycles. This is the reason we recommend that both the cold and hot sides of the shower pass through the regulator. This way your pressure fluctuations are regulated equally on both sides. Giving you a consistent blend of hot and cold which results in a more comfortable shower.

REFLECTING ON A CHANGING WORLD: Remember, this is not the fault of the intelligent design of modern tankless water heaters, it is related to the fact that they are designed and built for the large portion of the worlds population that have a supply of water delivered to the home under a consistent level of pressure. Even some towns have varying pressure depending upon the time of day and how many residents are using the central system. But, these systems are so large that pressure fluctuation happens at a very slow pace. A change that the heater can easily manage. Well systems with rapid pressure changes are the only scenario that is difficult for a modern tankless "smart" heater to manage and control. With an antiquated large holding tank-type water heater, the heater did not respond to flow and pressure changes as it simply heated that big tank of water at a very slow pace. Day in and day out, it ran to keep that big tank hot for the moment when the homeowner needed water. Kind of the same thing as keeping the car running in the driveway in case it was needed and we all know that is not the thing to do. The reason the temperature did not fluctuate with the old tank type system was because as the well-pump turned on and off, the pressure fluctuated equally on both the hot and cold sides. Therefore making the temperature constant. As the world becomes more energy efficient we all need to make some changes. This is really no different than switching from a large car with a large engine to a small car. We know that there is not as much room inside the smaller car and it typically has less power of the engine. The "economy" of the small car is a trade-off for the size and power of a larger car. As we know, there is a trade of some kind for energy savings. A carburetor for more complicated fuel injection for example. The primary reasons that people switch to smaller cars is to reduce the operating costs of driving and to save energy. Once the pressure of the well system is controlled the tankless water heater will operate as designed and deliver a consistent temperature of water within it's GPM specified parameters as well as saving energy thereby reducing utility costs.

NOTES : These tips are for professional use only, we accept no responsibility for those who try to work on their systems themselves. It is ALWAYS BEST to ask a professional to make these adjustments for you.

Natural Draft Installation Tips

Tue, 11 Feb 2020 15:04:40 GMT

Tips for proper installations of a natural draft tankless water heater for indoor use.

WARNING: RISK OF CARBON MONOXIDE POISONING FROM BACK-DRAFT.

PLEASE READ: This page and understand that back-draft of exhaust is not only a potential risk for Carbon Monoxide Poisoning, but can ruin your tankless water heater.

IMPORTANT NOTE: Few installations of natural draft tankless heaters made by any manufacturer meet combustion air requirements. They simply require mounting in a large open room. Few homes and cabins have a "unconfined" combustion air space that is large enough. "Unconfined" means an open room with no closable doorways or openings. (Even the largest garages and basements seldom meet these minimum cubic feet interior space requirements) There are standard codes that require minimum cubic feet of room space relating to the btu capacity of gas fired appliances.

For example: Our EZ-101 model is rated at 12kw/41,000 btu. At the standard recognized code for gas fired appliances being a minimum of 50 cubic feet of combustion air supply per 1,000 btu. This means that our EZ101 requires an open room "unconfined" combustion air space of 2050 cubic feet. (Our 81,891 btu EZ-202 requires 4050 cubic feet of combustion air space if mounted in a building).

In comparison, A standard 66/72 passenger school bus interior is 8 foot wide and 6 feet tall and about 35 feet long. Standard exterior length is 39.5 feet (class "B" CDL). Therefore, the interior of a typical school bus is 1680 cubic feet which is still 20% too small for our EZ101 heater to meet the minimum indoor mounting combustion air space code. A typical 26X24X8 two-car garage has almost exactly 5000 cubic feet of combustion air.

NOTE: If more than one gas fired appliance is in the same room, the btu ratings of all appliances must be added together and the room combustion air space must not be less than the local, state, or Federal code requirements. This is the reason that ALL manufacturers of tankless heaters recommend that indoor installations be made using only a direct vent model. We consider the natural draft models to be used only for uninhabited large buildings, barns, large storage sheds, lean-to, and outdoor type applications. We do not recommend that natural draft tankless heaters be installed indoors for any reason.

A natural draft tankless heater has no blower fan and does not connect to an A/C power source. A natural draft type tankless heater takes it's "intake" combustion air from inside the room in which the heater is mounted. It then uses a natural draft to pull the exhaust out through a flue pipe exhaust.

NOTE: This page and the information on this page does not apply to any EZTANKLESS brand tankless heater that is direct vent (connects to A/C 110V power supply).

The PROBLEM:

The tankless heater freezes internally because cold air is drawn into the exhaust while the heater is not turned-on. This especially can happen during the night in cold climates.

The CAUSES and the components explained:

If a natural draft tankless water heater is installed indoors and vented through the roof or a wall, when your furnace turns on during the cold winter months, there is a possibility that the furnace can draw cold air from outside through your tankless water heater exhaust.

THIS APPLIES TO: Any gas-fired appliance that uses room air for combustion and exhausts to the exterior of the home, cabin or building including exhaust hoods over ranges can cause your tankless heater to freeze.

THIS INCLUDES USERS OF FIREPLACES, WASTE OIL FURNACES AND WOOD OR COAL BURNING STOVES. The "back-draft" caused by the suction of other devices will bring cold air into the tankless heater through the exhaust pipe (flue) and this cold air will travel over the heat exchanger. Over a short period of time this can cause tubing inside the heat exchanger to freeze. The subsequent expansion from frozen water inside the heat exchanger will cause cracks and breakage in the interior of the heater. This will lead to a substantial water leak when the heater thaws and usually the tankless heater itself is irreparable.

THIS CAN BE AVOIDED! Please follow the simple step below to protect your water heater from unwanted freezing.

The SOLUTION:

Install your natural draft tankless water heater exhaust so that it is drawn into the draft of the main chimney. This way you are eliminating the risk of cold air being pulled down your exhaust pipe when the tankless heater is not running. As well as the risk of exhaust gas back-draft when the tankless heater is running at the same time as another "fired" and exhausting device. Basically, this is all about the fact that; fire of any kind consumes air and the air flow of this process of combustion needs to be understood and controlled.

CAUTION: We do not claim to be the authority on this type of technology. In fact our company recommends that indoor installations of any tankless heater be done using only a DIRECT VENT model. ( EZ-Ultra or EZ-Deluxe )

Information for "Remote" Users: Cabin, Camping, Barn, Tool-Shed, or Workshop.

DISCLAIMER: We cannot be held responsible for freeze damage as this is a common problem with the draft type tankless heaters from all manufacturers. We make every effort to explain these scenarios on our web site at the appropriate locations for every one of our products that are of this type of construction. If you live in a cold climate, most experts agree that a direct vent is the best type of heater to use. The reason manufacturers are switching to direct vent (See our "Deluxe" model) or (See our "Ultra" model) is because of several reasons which include the possibility of back draft freeze damage.

CAUTION: In cold climates FREEZING AND RELATED TANKLESS HEATER DAMAGE IS POSSIBLE.

If installing a natural draft tankless water heater inside any enclosed farm or industrial building or workshop, if the natural draft tankless heater shares the same space as any combustion device that has an exhaust pipe of any kind, there is the potential for a back-draft.

EZ Tankless at the Earl Park Fall Festival - Labor Day Weekend 2009

Tue, 11 Feb 2020 15:02:08 GMT

The EZ Tankless boys find themselves hard at work in their home town of Earl Park at the Fall Festival.

We find ourselved engourged in the mayhem at the Fall Festival. It is quite an event, bringing over 50,000 people to a town of 400 over the Labor Day weekend. It is a time of great food, great fun, and most importantly great people.

Everywhere you look you can find a smile on someones face. Even Jim was feeling a little wacky!

There are many food vendors and with EZ Tankless' booth right amongst the path for food, you better believe we found our way in to line. Eating at the Cardinal Roost is always the best and least expensive way of eating at the Fest, but if you want to eat there you better get in line fast, because it fills in minutes.

EZ Tankless had its fair share of interest. Many people could not believe when we showed them the EZ 101 attached to a garden hose and small LP tank.Many asked questions about the EZ Deluxe and marveled at the dual chamber intake/exhaust pipe. We tried our best to teach people of the advantages that come with installing a tankless water heater into their home.

But the Fall Fest isn't all about EZ Tankless, you must come to Earl Park to experience the Festival. There are constant Bluegrass concerts along with those that are just jamming along the sidelines. The food is great, and what can be better then eating sweet corn in Indiana. There were even some small rides for the kids.

It was a great time at the Earl Park Fall Festival this year, we hope to see you there next year.

EZ 101 + EZ 202 Limit Switch Bypass

Tue, 11 Feb 2020 15:00:24 GMT

Every EZ Tankless water heater contains a limit/safety switch. This is a heat sensitive switch that will shut down the heater if it reaches temperatures to high. Like all mechanical devices, a limit switch can fail. When the limit switch in the EZ Tankless fails, it closes the circuit keeping the heater from functioning without its use.

We can test the limit switch by bypassing its use and completing the circuit it has closed. Follow these simple instructions to open your EZ 202, and bypass the limit switch to test that it is still working properly.

Step 1. Remove Case Screws – Located on the bottom of the heater are two Phillips style screws. You can easily remove these two screws.

Step 2. Remove Burner Control Knob – Inside of the display panel is the Burner Selection Knob. Remove this knob before trying to remove the cover.

Step 3. Move the levers on the bottom of the heater to center position, so that they are lined up with the holes cut into the case to allow removal. When we have these centered we can lift up on the bottom of the cover. The cover will slide up, still attached at the top by small tabs. When you have the cover lifted, you can slightly push it forward to come off of the tabs on the top. We have circled the tabs in red in the picture below.

Step 4. Disconnecting the limit switch wires. In the top right corner of the heater you will find a small circle device with two wires attached to it. This is the limit switch (circled in red below). Disconnect the two wires running to the limit switch using needle nose pliers.

Step 5. Jump a wire across the two wires. Using a short piece of wire, connect each end to one of the plugs from the limit switch wires. This will complete the circuit and should allow the heater to run when tried again.

If your heater runs after jumping a wire across the limit switch wires, please call our Tech Support Line at (219)474-6658 and let us know you need a new limit switch.

EZ Tankless never recommends running a heater with a bypassed limit switch unless for testing purposes.

EZ Supreme - A Tankless Water Heater for Larger Homes

Mon, 10 Feb 2020 23:15:18 GMT

EZ Tankless has been working feverishly to finalize the all new EZ Supreme Tankless Water Heater. The EZ Supreme will be the large home tankless offering from EZ Tankless, with the ability to supply enough hot water for up to 4 showers operating at the same time.

So far there is not a lot of information to divulge, but we can tell you that it will use the direct vent intake/exhaust system like the EZ Deluxe and EZ Ultra tankless water heaters, although it will use a larger diameter pipe.

The EZ Supreme will use 3/4" water and gas connections, allowing for maximum flow through the heater without resistance.

Until more is known, we will leave you with an image of the upcoming heater.......

EZ 101 Ignition Switch Test

Mon, 10 Feb 2020 23:13:57 GMT

The EZ 101 contains a small ignition switch that is tied into the inlet water flow. When water flows through the heater it lifts a small screw off of the switch completing the circuit to the igniter.

If you do not hear the heater trying to ignite, we would always recommend first checking the batteries. Make sure to use alkaline batteries and that they are properly installed. If the heater still fails to ignite, you can follow these steps to test the igniter.

Looking at the bottom of the heater locate the two screws holding the cover on.

Step 1. Remove Case Screws – Located on the bottom of the heater are two Phillips style screws. You can easily remove these two screws.

Step 2. Remove Control Knobs – There are three knobs on the heater, they will slide off when pulled.

Step 3. Pull the cover up then shove forward. Be careful not to damage the wire connected to the power switch located on the bottom of the heater.

Step 4. You can find the ignition switch located front and center of the heater, just to the left of the drain plug. With the power switch in the on position, lift this switch and listen for the electric igniter to spark.

If you do not want to remove that cover that is fine. Most people can usually reach the ignition switch with their index finger by reaching through the openings in the bottom of the cover for the EZ 101.

If your heater sparks after lifting the screw off the switch, we would then recommend disconnecting all hoses and attachments from the hot water outlet and let water free flow through the heater.

If the heater sparks and ignites, we can assume the problem is in the water flow after the heater.

If the heater sparks and ignites for only a few seconds, we would recommend reading our article on how to test the limit switch.

If the heater sparks and does not ignite, we would recommend trying a new gas regulator, something set at 11"WC for propane or 8.5"WC for natural gas.

If the heater does not spark, please call our Tech Support line at (219)474-6658.

The Complexity of A Simple Tankless Water Heater

Mon, 10 Feb 2020 23:07:48 GMT

EZ Tankless realizes that most homeowners currently use a tank-type conventional water heater. We also realize that most homeowners have only ever used a tank-type conventional water heater. We understand that the idea of heating enough water to run an entire house while it is passing through a heat exchanger seems unreal. But tankless water heaters are a great way to heat water and most new homes are being built to use a tankless rather than tank-type water heater.

HOW THEY WORK

Tank-Type - A conventional water heater stores water in a large tank (50 Gallon is average for most American homes). This water is slowly heated by a gas powered flame or stream of electricity running to a diode. The water is heated until it reaches a set temperature, then the heater lowers the flame or shuts off the electricity, allowing the water to slowly cool. The water then cools until it is used or until it reaches the low end temperature setting, where it is then heated once again. This is an endless cycle of energy use until the water is used or the unit is turned completely off.

Tankless - A tankless water heater uses a much more complex but still very simple method for heating water. When a homeowner opens a faucet in the home, the water begins to flow through the water pipes as well as the tankless heater. There is a flow sensor installed in the heater, along with temperature probes. These devices tell the heater the incoming water temperature, followed by the current flow rate of the water. The heater then self determines just how much gas or electricity to use to heat the flow of water to the desired temperature set on the thermostat. The heater lastly records the outgoing temperature of the water to be sure it is creating the desired temperature.

PROS AND CONS

PROS

Tank-Type

Ease of installation. Most homes currently have a conventional tank-type water heater, therefore installing a new unit would only entail replacing the current heater with the new heater.

Stored Hot Water. With hot water in constant storage, you are always guaranteed hot water fast to your outlet.

Tankless

Energy and Money Savings. We grouped these together as they go hand in hand. With a savings in energy usage comes a savings in money spent. Because you are not storing and constantly reheating water in a stored tank, you will use much less gas and never experience stand-by energy loss.

Endless Hot Water. Because you are heating the water as it flows through the heater there is an endless supply (or limited to the amount of water you can flow). Absolutely NO RECOVERY TIME.

More Precise Water Temperature. Using all of the latest technology allows for a constant water temp every time you use your tankless unit.

CONS

Tank-Type

Stand-By Energy Loss. This occurs when you are away from the home or anytime you go a few hours between hot water usage. The hot water in your tank cools, and your heater must reignite and heat the water to be sure that it is ready for use when the demand comes.

Stored Water. Any kind of stagnant water is a birthplace for bacteria and contaminants.

Tankless

Installation Costs and Methods. Finding a quality plumber that has experience installing tankless water heater is becoming easier, but can still be quite costly. When it comes to the average home owner installing a tankless water heater, it must be understood that it can be done, but there are certain measurements that must be taken to guarantee that your tankless water heater will work at 100%.

Condensing vs. Non-Condensing Tankless Water Heaters

Mon, 10 Feb 2020 23:02:01 GMT

To the Point - Traditional tankless water heaters heat the water when called upon as it passes through a burn chamber without utilizing the thermal energy given off by the exhaust gases. Condensing units use that thermal energy of the exhaust gases by passing the water through an initial heat exchanger that houses those exhaust gases before they are pushed outside, thus preheating the inlet water before it enters the main burn chamber. In turn, condensing units operate at a lower BTU, raise the efficiency above 90%, as well as maintain the same gallon per minute when compared to similarly sized units.

Exhaust gases produced by a tankless water heater can reach temperatures upwards of 300°F, which is why traditional units require venting with non-corrosive metals (Category-3 Stainless Steel) to protect from condensation. This can become costly as most tankless water heaters do not come with the venting kit, though all EZ Tankless household water heaters do come with a venting kit. After figuring in the total distance of flue needed, you could be spending an extra $200-$500 after purchasing the unit. The exhaust gases exiting a condensing tankless water heater expel at a much lower temperature, usually around 100°F - 170°F, because most of that thermal energy is used to preheat the inlet water through the initial heat exchanger. Therefore, solid-core schedule 40 PVC/CPVC can be used to exhaust the remaining gases out of the home, which can be half or even a quarter of the cost of using stainless steel.

Not only is venting more cost effective with a condensing tankless water heater, but they’re also more efficient. All condensing tankless water heaters run above 90% efficiency, while non-condensing tankless water heaters usually run in the 80% range.

The cost of condensing units is currently greater than traditional, due to the second heat exchanger that raises the efficiency, but frankly… traditional units are on their way out. They have served us well and will continue to do so in portable and off-grid applications, but there’s no room in the home for them anymore. Condensing units are less expensive to vent, they operate at a lower BTU, and they’re overall more efficient… saving YOU the homeowner more money!
