Geothermal heat pumps Geothermal heat pumpsA system that consists of indoor pump equipment, a ground loop, and a flow center to connect the indoor and outdoor equipment. The ground loop uses the temperature of the earth or water, several feet underground, to heat or cool the dwelling. A pump circulates a temperature-sensitive fluid through this ground loop buried below the freezing line where the temperature stays constant at approximately 60 degrees F. The heat pumps transfer stable temperatures into houses in reverse order according to the season. In the winter, warm fluid carries heat into the house, and in the summer, cool fluid draws heat out of the house. |
