Geothermal Heat Pumps - Detailed

When in a heating configuration, water is moving through the underground lines (or loop circuit) which causes the warming energy of the earth to be transferred. Once the heat from underground transfers to the water, the water is then forced through an above ground heat exchanger which lives inside the heat pump.

The water passing through the heat pump and heat exchanger, it sheds (or transfers) heat energy to a refrigerant. The refrigerant which is in a gas form is warmed and heated, and then directed to compressor section. At the air compressor stage, the refrigerant is cranked up to approximately 155 degrees fahrenheit.

Once the refrigerant gas has reached it's full temp, it is send to yet another heat exchanger, where it sheds and transfers heat energy in large quantity. This is the stage where the geothermal heat pump forces (or pumps) the heat into the central heating and duct system.
