How Geothermal HVAC Works
Ground/water source heat pumps are the most efficient heating and cooling technology available today. A ground source heat pump gets its heat from a circuit of pipes buried in the ground. A solution with antifreeze circulates through the pipes picking up the natural heat of the earth which is extracted by the heat pump.
A water source heat pump can be used if you have a well, pond, stream or lake. In this case the water is pumped to the heat exchanger where its heat is extracted (or rejected) and the water is returned to the source.
In both cases, the process is reversed in summer when heat and humidity are drawn from the house to provide central air conditioning.
Aside from cutting your heating and cooling bills by up to 75% and giving you extremely efficient air conditioning, ground/water source heat pumps can also lower your water heating costs on average by 50% by providing free heat for the hot water tank when your air conditioning is operating.
Benefits of Geothermal HVAC
Compared to electric resistance heating, a ground source heat pump may save you up to 75% on your utility bill. Some models also provide virtually free water heating.
– Geothermal maintenance is minimal because there are fewer parts in the system and the unit is operating with a constant ground temperature instead of extreme outdoor temperature swings. Once installed, annual or bi-annual services are recommended. Filter systems are usually designed to be replaced annually instead of monthly, which is an additional savings.
