Heat Pump Air Conditioning System in Toronto – Geothermal Heating.

Geothermal heating harnesses natural thermal energy from within the Earth’s crust for water and space heating. This method of heating is hailed for its energy efficiency, lack of pollution, and financial benefits. Areas such as Iceland with abundant geothermal sources, called hot spots, can freely use the energy for heating. Regions lacking hot spots can also achieve geothermal heating, however, using a geothermal heat pump.

A series of pipes are set up in a loop beneath the house and cooled water is pumped through. As the water passes through the ground, it conducts heat, which is then re-extracted in a heat exchanger below the house. The heat that the exchanger pulls from the water and the heat created as a byproduct of the exchanger’s work are used to heat the house. When the loop is reversed and warmed water is pumped through the ground to lose heat in the relatively cooler soil, the system can be used to cool the house. Geothermal heating uses far less energy than electric heating and cooling or an air source heat pump.

Geothermal heating is celebrated for several environmental and financial reasons. This method of heating draws energy from a renewable source and creates less of the pollution common to burning fossil fuels. From a financial perspective, geothermal heating systems require less maintenance, last for decades, raise the value of a building, and cut costs normally accrued in monthly oil or electric bills.
