How Energy Efficient Is GHP (Ground-Source Heat Pump) Technology
Geothermal Heat Pumps (Ground-Source Heat Pumps) are
electrically powered home heating and cooling heat pumps which transfer
heat to and from the earth via a refrigeration process. Geothermal Heat
Pumps have been in operation for over 50 years and operate on the same principle
as your household refrigerator or air conditioner.
During winter operation heat energy is absorbed from the ground via underground
tubing or by pumping well water to the heat pump. The heat pump mechanism
concentrates this energy and delivers it to the home in the form of warm
air or hot water.
During summer operation the process is reversed. Warm air is collected from
the home and rejected to the cooler earth. On most models, domestic hot
water is produced any time the heat pump operates.
Geothermal Heat pumps are available for both forced air and radiant floor heating
systems in a variety of output capacities which can accommodate any building
design.
