Closed Loop Geothermal Well System A Closed Loop System utilizes a water or antifreeze solution circulated through plastic piping buried beneath the earths surface. During the cold winter months the fluid utiizes the heat from the earth and carries it through the system and brings it into the building, in the summer this reverses by pulling the heat from the building carrying it through the system and placing it back into the ground. The added benefit of this process is free hot water in warmer months and significant savings in winter months. |
