California Residence Heated and Cooled by Geothermal Heat Pump


One of the largest homes in Northern California is owned by Frederick Corson’s . He is proud with the very low heating and cooling bills. 

Carson fitted his residence with a ground-source heat pump known as a geothermal heat pump. The pump and pipe installation are environmentally friendly and sustainable, while they also keep the costs of heating and cooling the house minimal. This whole system works on the principal that regardless of the temperature on the Earth’s surface, it is always 60 degrees a few feet underground.

A geothermal heat pump is installed by first drilling holes 200 to 300 feet deep and then inserting U-shaped tubes into them. These earth-heat exchange tubes are then connected to a primary heat exchanger.  The tubes are filled with a solution of water and alcohol, which prevent corrosion and freezing.

The owner of the 5000 square foot home in California turn on this heating system in November and and keep it on through April. In the summer, the geothermal heat pump system can also be reversed to cool the house. To do this, the pump pulls the warm air out of the house and transfers t into the ground.
