Geothermal Heat Pump:
A geothermal heat pump, also known as a ground source heat pump (GSHP), is a unit that uses the Earth as a heat source. Heat pumps move heat from a source to a sink. With GSHP's the source is the ground outside and the sink is the heating system within the house. They use the same basic system as a refrigerator, which transfers heat from the inside of the refrigerator (source) to the outside (sink).

Heat pumps are characterised by two loops, the source or external loop and the sink or internal loop. The heat pump collects the heat stored in the Earth (source) via the external loop and delivers it to the inside loop (sink) for use in the heating system. The Earth below the frost line remains at a relatively constant temperature year round. This temperature equates roughly to the locations average annual temperature, so is usually 7°C to 9°C. Because this temperature remains constant GSHP's perform with greater efficiency and in a far larger range of extreme temperatures than other types of heat pumps.
