A. We protect residential electric, natural gas, and propane fueled water heaters – no matter the age of the unit. Water heaters fueled by oil, solar, or geothermal energy are not eligible. In addition, tankless water heaters, water heaters larger than 50 gallons or intended for use in commercial properties, and combination heating/domestic hot water units are not eligible. Water heaters that are designed to be attached directly to the wall or placed on a platform that is attached to a wall are not eligible for this program. If your home has more than one Water Heater, each Water Heater must be enrolled in a separate program in order to be eligible for a repair or replacement under this program.
