Heat Pump Water Heaters

Although they can have a high initial cost, heat pump water heaters have the potential to reduce water-heating costs by as much as 50%.

Heat pump heaters use to move heat from one place to another instead of generating heat directly. To heat water for homes, heat pump water heaters work like refrigerators in reverse.

Heat pump water heaters can be purchased as integral units with built-in water storage tanks or as add-ons that can be retrofitted to an existing tank. These systems have a high initial cost. They also require installation in locations that remain in the 40? to 90? F (4.4? to 32.2? C) range year-round and contain at least 1000 cubic feet (28.3 cubic meters) of air space around the water heaters. To operate most efficiently, they should be placed in areas having excess heat, such as rooms. They will not work well in a cold space.
