How Geothermal Energy Works

Geothermal systems get most of their energy from the consistent temperature of the earth. In our northern climate, the earth remains a constant 50 to 55 degrees year round.

In the winter time, this heat is absorbed by the loop system and carried into the geothermal furnace where it is compressed to a higher temperature. The result is a warm and comfortable home.

In the summer time, the process is reversed. The warmth of the air in the home is absorbed by the geothermal furnace and deposited into the cooler earth through the loop system. The result is a cool, dehumidified, comfortable home.

While heating and cooling the home, some geothermal furnaces can capture excess heat and use it to heat hot water for your domestic use.

    How Geothermal Works

    Geothermal Benefits

    1. Clean: No combustion, more run time for air filtration.
    2. Quiet: Insulated cabinet and duct work, soft start fans, wrapped compressors.
    3. Safe: No flame or exhaust from combustion.
    4. Green: Gets most of its energy from the renewable energy stored in the earth.
    5. Efficient: 1 unit of electricity combined with up to 4 units of energy from the earth = effective 500% efficiency.
    6. Flexible: One furnace to perform many tasks: heating, cooling, hot water, radiant heating.
    7. Reliable: Few moving parts, all inside the home away from the harsh elements.
