Geothermal Heat Pumps

Geothermal Heat Pumps maximize efficiency by using the constant temperature of the earth as the exchange medium instead of the outside air temperature.

A few feet below the earth's surface, the ground remains at a relatively constant temperature.

Depending on latitude, ground temperatures range from 45°F to 75°F. This ground temperature is warmer than the air above it during the winter and cooler than the air above it in the summer. AAON Geothermal Heat Pumps take advantage of this constant temperature by exchanging heat with the earth through a ground heat exchanger.
