The Complexity of A Simple Tankless Water Heater
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
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.
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 everytime you use your tankless unit.
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 comtaminants.
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%.
