Geothermal heating and cooling systems are definitely the most efficient and environmentally friendly systems on the market. They work differently than conventional systems by taking advantage of the sun?s solar energy that is absorbed and stored by the earth. At a depth of 20 feet the ground maintains a fairly constant temperature of ranging from 45 to 77 degrees F depending on your region.
Pipes in the ground circulate a water solution and carry energy to the heat pump in the winter for heating and remove heat from the building into the ground in the summer. Forced air or low temperature hydronic systems distribute geothermal heating and air conditioning. Most systems use electric heat pumps capable of increasing the ground?s thermal energy in the winter and concentrating and depositing the a building?s thermal energy into the relatively cool ground in the summer when air conditioning.
