Geothermal Heat Pumps
Geothermal Heat pumps are electrically powered home heating and cooling devices which transfer heat to and from the earth via a refrigeration process. 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.
Natural Renewable Energy
Solar heat which has been stored in the earth’s crust provides
the inexhaustible source of supply energy for a geothermal heat pump.
This energy is replenished each year by the sun during the normal cycle
of our seasons. There is enough energy stored beneath each building
to more than supply the cooling and heating requirements. All we need
to do is extract that energy and the geothermal heat pump has been designed
to do just that!
When compared to an electrically heated home, geothermal heat pumps consume less than 1/3 the amount of electrical energy to heat the structure. Consequently the electric utility company generates only 1/3 the emissions it normally would.
What can a home owner expect from a geothermal heat pump?
