What is Geothermal Heating & Cooling ?
Geothermal heating uses the relatively constant temperatures found a few feet under the ground to regulate the temperatures in your home. This system pulls heat into your home from the Earth in the winter and moves heat away from your home in the summer. It uses two components, a heat exchange and several hundred feet of piping, often called a "loop". During the summer, the liquid in the loop draws heat from the earth as it circulates. In the summer, the heat is carried away from the home in the liquid and is absorbed by the ground.
