Geothermal systems use the earth’s temperature to produce reliable and cost-effective energy for heating, cooling, and water heating. Even with Wisconsin’s extreme climate, temperatures remain consistant just a few feet below the ground’s surface. Geothermal systems exchange these even below-ground temperatures with fluctuating indoor, above-ground temperatures. When combined with a large loop field or well, this results in significantly greater efficiency than traditional heating systems.
Geothermal heat pump systems are sometimes referred to as earth-coupled, ground-source, or water-source, but they all refer to the same type of renewable energy.
