What is a Heat Pump?
A heat pump is a device for moving heat from one location to another. In the case of pool heat pumps heat is taken from the surrounding air and transferred to the pool water. A heat pump providing heating for a house is likely to be a ground source heat pump where the heat is taken from the ground using a length of well buried pipes. The efficiency of air source heat pumps declines with the air temperature and ice formation is a problem at low temperatures.  Click Here to read more.
