A geothermal heat pump is an electric heat pump that exchanges heat with the ground or ground water, instead of air. This is more efficient because the temperature of the earth 10-15 feet below the surface remains around 55 degrees F throughout the year (the average temperature and range of temperatures depends on location), providing a better heat transfer medium than outdoor air, whose temperature can vary by more than 100 degrees F. An "open loop" geothermal heat pump uses groundwater from a well as the heat source/heat sink. Once it has circulated through the heat pump(s), the water is returned to the ground through the same well, a separate injection well, or through surface discharge. In a "closed loop" geothermal heat pump, water (or a mixture of water and anti-freeze) from the heat pumps is circulated either to horizontal or vertical pipes that are in contact with the earth. After exchanging heat with the ground, the water is circulated back to the heat pumps in a closed loop.
