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.
