Used around the world for thousands of years, geothermal energy offsets the need for electricity and natural gas. A geothermal system can provide at least two thirds of the energy needed to heat a home. Geothermal systems can transfer three to four units of energy into a home for every one unit of electricity used which may result in home heating savings of 30 to 70 percent; and, less carbon dioxide and atmospheric pollutants are produced by a geothermal system than a conventional heating and cooling system. No additional fuel delivery systems are needed, other than electricity, and venting of combustion products is needed.

Geothermal systems use the constant temperature of the ground to regulate the temperature of a building at very high effective efficiency. The system does not create heat through combustion of fuel or passing electricity through resistors, it simply moves heat from the ground to the building for heating. And in the opposite direction for cooling. In a geothermal system, a pipe filled with fluid is buried beneath the ground. That fluid then absorbs the heat from the earth. This fluid then passes through a heat exchanger that extracts the heat and distributes it through the house via forced air ventilation or a radiant heating system located under the floor, behind walls, or in the ceilings.

During hot weather, the fluid that continually circulates in the pipes absorbs heat from your home and transfers it back into the earth. A few metres below the surface, the ground holds a constant temperature regardless of the weather.
