Geothermal Heat Pumps
An illustration of geothermal heat pumps. Geothermal heat is a central heating and cooling system that uses the earth as a heat source (in the winter) or a heat sink (in the summer). This illustration outlines five types of heat pumps: a pond loop, an open loop, a horizontal loop, a slinky loop and a vertical loop.
