A heat pump is an electrical device that extracts heat from one place and transfers it to another. A heat pump, when used for heating a house, can be 2-4 times more efficient than using electric baseboard, a boiler or a furnace. All heat pumps can be reversed and used to cool a house down. There are four main types of heat pumps:
- Air to Water Heat Pump – Takes the heat out of the outdoor air and transfers it into water that can then be used to heat your home, domestic hot water, pool and hot tub. Air to water heat pumps are often used in conjunction with radiant floors to heat a home.
- Air to Air Heat Pump – Takes the heat out of the outdoor air and transfers it to your home via an air handler and a series of ductwork. If your home does not have ducts, air to air heat pumps can also be used with ductless units that hang on the walls throughout your home.
- Water to Air Heat Pump – Transfers heat to or from a geothermal system to your home using ductwork throughout the home. Water to air heat pumps can be used to heat and cool your home. You can also preheat your domestic hot water using a superheater that is located inside the heat pump.
- Water to Water Heat Pump – Transfers heat to or from a geothermal system to your home. The hot water can then be used to heat radiant floors, pools, hot tubs and preheat domestic hot water.
