What is a Geothermal Heat Pump?
Geothermal heat pumps use the relatively constant temperature of soil or surface water as a heat source and sink for a heat pump, which provides heating and cooling for buildings. Geothermal heat pumps produce heat more efficiently than furnaces, boilers and air-source heat pumps. The higher cost of installation of this type of heat pump is usually offset by low costs for operation and maintenance.
