Heat Pump use pipes filled with water and antifreeze buried in the ground to extract the heat found there. The heated water is then run through a heat exchanger in a heat pump to get concentrated to a higher temperature. It circulates through your chosen heating system to heat your home and water. It is then circulated back through the ground to get more heat. The ground stays at a constant temperature all year so is a constant source of heat.
