Advantages of geothermal systems:



 Geothermal systems use the earth as a heat source and heat sink. In order to transfer heat to or from the house, heat exchangers [ground loops] are installed in the ground. These consist of high density polyethylene plastic pipes. The loops are then connected to the heat pump and fluid is circulated through the loop piping, transferring the heat between the heat pump and the earth.

 First you should realize that the earth absorbs and stores nearly half of the sun’s solar energy. As a result, at a depth of six feet it maintains a fairly constant temperature of 45 to 70 degrees Fahrenheit. The geothermal system taps into that free, renewable energy and puts it to work.

 In the summer, this process is reversed in order to cool the home. Heat is drawn from the home, rejected to the loop and absorbed by the earth. The result is a comfortable home all year round. Since most of the energy used for heating and cooling is free from the earth, geothermal systems are the most efficient and environmentally friendly systems on the market today.
