Extracting Heat From The Earth | AltEnergyMag
The answer to the success of a geothermal system is that it's using negligible energy to extract the heat from the earth during the winter and it transfers that heat into the home. During the summer, the reverse happens and the system extracts the heat from the home and disperses that heat into the consistent temperature of the earth.
