Heat pumps have traditionally been used for space conditioning, but are now also being used for electric water heating. They are usually three times more efficient than electric resistance water heaters--meaning that they can produce the same amount of hot water for one-third the amount of electricity. Stand-alone heat pump water heaters (HPWH), which are described here, are different from heating and cooling heat pump systems that have integrated water-heating capability. As an Award Winning Asheville NC Custom Home Builder we are always educating clients on new technologies available to save energy in their new home.
There are four basic types of stand-alone HPWH. The heat pump can be integrated with or separate from the hot water storage tank, and cool exhaust air can be exhausted to the room or to the outdoors (see Figures). Because HPWH take heat from the surrounding room air, they cool and dehumidify a space. This is a benefit during the cooling season and a drawback during the heating season.
