The ground under our feet maintains a nearly constant temperature between 50 and 60 degree year-round. Large bodies of water, such as oceans or lakes, also tend to keep a fairly even temperature year round. Geothermal heating and cooling systems – also called ground-source heat pumps – provide all-season comfort by tapping the energy that is naturally stored in the earth. This energy isn't just renewable: it is constant.
