In the purest sense, geothermal systems use solar energy. The earth absorbs an amazing 48% of the sun’s energy, leaving a fairly constant underground temperature between 45 and 70o F.
A water solution flows through pipes buried in the ground (ground loop system) absorbing heat from the earth in the winter and moving it to the geothermal system inside the house. Once there, the heat is condensed and transferred to the air that is circulated throughout the home, providing warmth when needed.
In the summer, the process is reversed, absorbing heat from the air inside the home, similar to how a refrigerator extracts heat from food to make it cool, and transfers that heat into the ground through the same loop system.
The diagrams to the right show some of the ways the ground loop system can be setup. Some may be applicable to your home, others maybe not. For more information, be sure to contact us and setup an appointment to come out and discuss what we can do for you!
