How it Works

Water circulates in the loop to exchange heat between your home, the ground source heat pump, and the earth, providing geothermal heating, cooling, and hot water at remarkably high efficiencies. In fact, ClimateMaster geothermal heating and cooling systems are 400-600% efficient and can cut your heating, cooling, and hot water costs by up to 70%.

How Does Geothermal Work for Residential Homes?

A geothermal system uses small-diameter, High-Density Polyethylene (HDPE) pipes buried underground called a "loop." The loop circulates water to move heat energy to and from your home. It''s the heart of a geothermal system and its biggest advantage over ordinary heat pumps, air conditioners and fossil fuel furnaces.
