As hot water heaters continue to evolve, another new entry into the market has been heat pump water heaters. Engineers wondered why the heat pumps that produce heat and cooling for a house could not be rigged to heat water as well. Voila! The heat pump water heater was born.
If you live in an area that does not get below freezing on a consistent basis, than a heat pump water heater could be a good bet for you. Most of the heat pump water heaters are geothermal heat pumps, meaning that they draw heat from the ground.
Thus, if you live in a cold region, such a heater will not work effectively. As with many non-conventional water heaters, the initial cost is higher and installation can get complicated, but the energy savings are substantial as well.
Heat pump water heaters can be purchased as a stand-alone unit or in combination with your space conditioning system. The stand-alone units have a built-in storage tank; the combo arrangement involves retrofitting your heat pump to power your existing storage tank.
Heat pump water heaters are reported to be 2-3 times more energy efficient than standard water heaters because they move heat from one place to another rather than generate it directly, operating like a refrigerator in reverse.
