How Does Geothermal Work?

 

55 degrees. This is why geothermal heat pumps are so energy efficient. The system extracts warmth from the ground even when it is below freezing outside. It can heat your home, and be connected to your hot water heater or radiant flooring. During the cooling season the heat in your home is extracted and either moved to the earth or into your hot water tank.
