EZTankless - Limited Warranty Terms and Conditions

EZtankless Direct Vent and Power Vent water heaters are warranted by the USA importer/distributor, EZtankless Inc. This warranty is applicable only for EZtankless brand tankless water heaters that are sold and used only within the boundaries of The United States of America.

Heat Exchanger warranty: (Direct Vent and Power Vent models only)

If the heat exchanger fails on a Direct Vent and Power Vent model within five (5) years after the original installation and operation, EZtankless will furnish a replacement heat exchanger. However, if the water heater is installed in other than a single family dwelling this heat exchanger warranty is limited to one (1) year from date of original installation and operation.

Warranty on Other Parts:

If any other part on a Direct Vent and Power Vent model fails within one (1) year after original installation and operation, EZtankless will furnish a replacement part free of charge.

EZtankless will furnish a replacement heat exchanger and will furnish a replacement of any other part which fails in normal use and service within the applicable periods specified, in accordance with the terms of this warranty. The replacement component(s) will be warranted for the unexpired portion of the original warranty. This warranty will be valid only for professionally installed water heaters remaining in possession of the original purchaser as recorded on the warranty card.

Shipping costs:

In addition to supplying the replacement part(s), EZtankless will provide ground service delivery for said parts. Expedited shipping will be charged to the customer.

Service Labor Costs:

This warranty does not cover any labor costs associated with service, removal or re-installation of part(s). All such costs must be borne by the Purchaser. Additionally, this warranty does not cover any labor costs associated with service, removal or re-installation of the original water heater or a replaced water heater.


The natural draft (non-fan-powered - battery ignition) camping and outdoor models in general have only a one year warranty against manufacturing defects. Example: model EZ101 outdoor camping heater has a one year limited warranty on manufacturing defects. The 101 has no additional warranty of any kind expressed or implied.

This warranty will not apply to:

  • to defects or malfunctions resulting from failure to properly install, operate or maintain the unit in accordance with the printed instructions provided.
  • to damage or abuse, accident, neglect or freezing and other acts of nature.
  • to damage resulting from operation with any modification of any kind, usage for purposes other than supplying hot water for a sink, shower, and laundry system. Or removal of or attempt to defeat any safety device and/or sensor. These heaters ar not for use for pools, spas, hot tubs, floor or wall radiant heating systems, industrial applications, or sprinkle systems.
  • to failure of the heat exchanger resulting from the operation of the water heater in a corrosive atmosphere or without a filter and/or water softener or at water temperatures exceeding the maximum rating, or if the water heater is not supplied with filtered or treated potable water.
  • to defects or damage cause by any attachment or modification, including any energy-saving device.

Additional Warranty Exceptions and Details:

The EZTANKLESS warranty terms do not cover FREEZE DAMAGE, SEDIMENT DAMAGE, MINERAL DAMAGE, breakage or any type of failure resulting from errors in the act of installation, or malfunctions, breakage or incidents relating to any of the following; malfunctions or failures of any kind directly resulting from improper installation or amateur installation, misuse or abuse, failure to perform required or proper maintenance, modifications of any kind, inadequate water quality and/or over/under pressure related damage, natural disasters and acts of riot, vandalism, or war.


Obviously, EZTANKLESS cannot be held responsible for damage due to freezing of water inside the unit. Outside units must be thoroughly drained or removed to a warm place in times of low temperatures. Indoor units should be mounted in a heated space such as the basement or utility room in proximity to warm room air. Installers should be aware of extreme freezing conditions that may exist along exterior walls, in garages or due to natural weather occurrences as well as anomalies. Please take special precautions when planning the location of the unit. This is especially applicable to those users in Northern USA latitudes and those units installed in buildings without a consistent and constant heat source. Upon inspection, it is relatively easy for our technicians to recognize freeze damage and this will not be considered for warranty replacement. However, it is sometimes possible to repair a freeze damaged unit. If your unit is damaged by freezing, you may wish to send it to our facility for inspection and possible repair.


Every tankless manufacturer requires that there be a pre-filtration and/or water softener installed on the inlet water line of the heater. It is simple, tankless water heaters do not have a tank and therefore have no internal surface area for sediment and minerals to collect. In addition, periodic flushing of the tankless heater is required to remove deposits and maintain proper operation. Upon inspection, it is relatively easy for our technicians to recognize sediment and mineral damage and neglect. Heaters returned to our company with this type of problem will not be considered for warranty replacement.

EZTANKLESS does not pay for labor or services regarding the diagnosis and repair of warranty related failures. We suggest that before hiring a professional for diagnosis and repair, the person(s) responsible for the water heater should contact our service personnel at our help desk.
