A heat pump is a mechanical compression cycle refrigeration system that is used to either heat or cool an area. Heat pumps work by transferring heat from one body, such as the ground, air or water, to another body. This can also be reversed to cool an area.


Heat pumps work by transferring heat energy between two areas. The most common type, the air-source heat pump, uses a coil of refrigerant to absorb heat from indoor air and transfer it to the air outside for cooling. In cold weather, the heat pump reverses the direction of heat transfer.


Heat pumps are electric devices that transfer heat from a colder area to a warmer one, allowing them to provide heat in a home when outside temperatures are cold and air conditioning when the temperatures outside are warm. They work on the same principle as a refrigerator.


Installation of an air-source heat pump for an entire home ranges from $2,000 to $8,000, according to CostHelper. The price of a heat pump system varies widely based on whether or not duct work is already in place and the type of heat pump system installed.


A heat pump may be the best way to heat a home for people living in climates where temperatures seldom drop below freezing as they are energy-efficient and produce a mild, even heat. Heat pumps are not as efficient in colder climates.


Heat pumps can be compared according to their overall efficiency, compressor types, motor types and noise levels. An individual should determine whether his local climate is appropriate for a heat pump before purchasing one. Heat pumps usually work better in areas with a moderately cool climate.


Common heat pump problems include accumulated ice, circuit breaker malfunction, draining problems, non-function and cold air. These problems are the result of weather elements and poor maintenance. Other minor problems include blocked coils, excessive noise, a malfunctioning blower and inadequate he


Heat pump covers are available at a variety of online pool supply stores including PoolHeatPumps.com, HeatPumpCovers.com and PoolSupplyUnlimited.com, as of 2016. Additional sources include Amazon.com and Wal-Mart.


Thermostats used on heat pumps vary significantly, but most have an setting to turn the entire system off and a setting to set the heat pump to create hot or cold air. They also have a setting for emergency heating.


Heat pumps can be purchased online and in-store from merchants such as Home Depot and Lowe's. Additionally, heat pumps can be purchased online from Amazon.
