Geoexchange is another word for geothermal heat pumps, ground source heat pumps, or ground-coupled heat pumps. Geoexchange is a “system” which allows heat to be moved from one source to another. The key components of a geoexchange system are: a ground loop (earth, pond, lake, or well), a ground-source heat pump, and a water circulation pump. Ground source heat pumps can be an attractive alternative for heating and cooling because they supply more energy than they consume by extracting heat from their surroundings. Note that heat pumps are all electric machines.

Below is an example of a ground-source heat pump operating in air conditioning mode. Heat pumps can also be used to heat domestic hot water, pools, and spas. Heat pumps can be used to make chilled water for air conditioning, refrigeration or process applications.
