What makes a GeoExchange system different from conventional heating and cooling systems?
Most space heating and water heating in Canada is provided by combustion of natural gas, oil or propane, or by electric resistance while most cooling is provided by electric air conditioning. A GeoExchange system does not use combustion to make heat; it simply transfers solar heat from the ground at very high efficiency. This lack of combustion makes a GeoExchange system the best choice from an environmental and safety standpoint.
