How does a heat pump reverse the normal flow of heat?
In a typical air conditioner, the refrigerant absorbs heat inside the home in the evaporator coils. Its temperature and pressure rise in the compressor, and it moves to the condenser coils to reject its heat outside. A heat pump reversing valve simply reverses the process by cycling the refrigerant the opposite way.
What is a heat pump, how does it work?
Simply put, a heat pump is a device that transfers thermal energy from one point to another. A common example of this can be found in our refrigerators where the evaporation and cooling of a liquid is used to lower the temperature of the storage compartment.

How does a water heater work?
While a refrigerator pulls heat from inside a box and dumps it into the surrounding room, a stand-alone air-source heat pump water heater pulls heat from the surrounding air and dumps it -- at a higher temperature -- into a tank to heat water.
What is a desuperheater?
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 the home's storage water heater tank. Desuperheaters are also available for tankless or demand-type water heaters. In the summer, the desuperheater uses the excess heat ...
Why do geothermal heat pumps work?
Because they remove heat from the air, any type of air-source heat pump system works more efficiently in a warm climate. Homeowners primarily install geothermal heat pumps -- which draw heat from the ground during the winter and from the indoor air during the summer -- for heating and cooling their homes.
How does a heat pump work?

By virtue of their unparalleled efficiency, HPWHs often cover their extra cost within a few years, and from then on any savings go right into your pocket.
How does a refrigerator work?
While a refrigerator expels hot air from inside its storage compartment , HPWHs accomplish the reverse, pulling heat in from the surrounding air.
How does a water heater work?
Conventional water heaters use energy—usually either gas or electricity—to generate heat. Heat pump water heaters (HPWHs) operate in an entirely different way. They, too, use energy, but not to generate heat, rather to move it from one place to another—from the air surrounding the appliance to the water held in the unit’s storage tank.
Do HPWHs cover extra cost?
