How Geothermal Systems Work

The Natural Way

Ground source heat pumps (GSHPs) are electrically powered systems that tap the stored energy of the greatest solar collector in existence—the earth. These systems use the earth's relatively constant temperature to provide heating, cooling, and hot water for homes and commercial buildings.

The earth absorbs almost 50% of all solar energy and remains a nearly constant temperature of 50 degrees to 70 degrees F depending on geographic location. In winter, a food-grade antifreeze solution circulating inside a sealed loop absorbs heat from the earth and carries it to the geothermal unit. Here it is compressed to a higher temperature and sent out as warm air or warm water to your indoor system for circulation throughout your home.

In the summer, the system reverses and expels heat from your home to the cooler earth via the loop system, creating an air conditioned environment. This heat exchange process is not only natural but is a truly ingenious and highly effective way to create a comfortable climate in your home or business.

Incoming Solar Radiation
The process of harnessing energy from geothermal depends on the relationship between the earth and the sun. The sun provides energy - the earth provides the storage of energy.
