Water Heating

Heat Pump Water Heaters

How They Work

Heat Pump Water Heaters (HPWHs) work like a refrigerator in reverse. While a refrigerator removes heat from an enclosed box and expels that heat to the surrounding air, a HPWH takes heat from surrounding air and transfers it to water in an enclosed tank. As a result, they can be two to three times more energy efficient than conventional electric resistance water heaters. HPWH models that are certified ENERGY STAR can save almost $300 annually on electric bills. Find information on HPWHs here.
