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. Learn more
