Choosing and Installing Geothermal Heat Pumps When selecting and installing a geothermal heat pump, consider the heating and cooling efficiency, the economics of the system, and your site’s characteristics. Be sure to find a qualified installer.
Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300% to 600%) on the coldest winter nights, compared to 175% to 250% for air-source heat pumps on cool days.
An energy-efficient heating and cooling alternative, the geothermal heat pump system moves heat from the ground to a building (or from a building to the ground) through a series of flexible pipe “loops” containing water. This edition of Energy 101 explores the benefits Geothermal and the science behind how it all comes together.
