Heat-pump water heaters are up to three times more energy efficient than conventional electric resistance water heaters since they use electricity to move heat from one place to another instead of generating heat directly.
The system works like a refrigerator in reverse. While a refrigerator pulls heat from inside and dumps it into the surrounding room, a heat-pump water heater pulls heat from the surrounding air and dumps it—at a higher temperature—into a tank to warm up the water inside.
- 1,000 cubic feet of air space around the water heater. Heat pump systems typically work more efficiently in warmer climates because they remove heat from the air.
- 1,000 cubic feet of air space around the water heater.
- An installation space with excess heat, such as a furnace room. Heat-pump water heaters will not operate efficiently in a cold space. They tend to cool the spaces they are in.
Get $150 Off a Desuperheater for Your Geothermal System
If you already have geothermal, you can earn $150 if you install a desuperheater to supplement your existing water heater.
A desuperheater is a small, auxiliary heat exchanger that uses superheated gases from the heat pump's compressor to heat water. This hot water then circulates through a pipe to a storage water heater tank.
In the summer, the desuperheater uses the excess heat that would otherwise be expelled to the ground to heat your water. During the fall, winter, and spring—when the desuperheater isn't producing as much excess heat—you'll need to rely more on your storage or demand water heater to heat the water. You can install a triple-function geothermal heat pump system, to meet your hot-water needs year-round.
To get started, find a participating contractor in the New York State Clean Heat Program. Your contractor will help find and install your heat pump, and deduct your rebate from the total project cost.
