How Does Geothermal Work?
Warm in the Winter: The Earth absorbs a huge amount of energy from the sun—more than 500 times the energy we need each year. Geothermal systems use this heat during the heating season at an efficiency approaching or exceeding 400 percent.
Cool in the Summer: The Earth absorbs energy, but it also acts as a buffer. At 5 to 7 feet down, the temperature of the Earth stays cool year-round. During the heat of summer, geothermal systems use the cool Earth to keep your home comfortable.
Heating or cooling, you win both ways.
