By sending a carrier fluid through underground pipes, a geothermal heat exchange system can extract heat from the ground during the winter to heat the home, or extract heat from the home during the summer to cool the home. This approach can save 30-70% in heating costs, and 20-50% in cooling costs, depending on geographic location. learn more |
