How It Works
Geothermal energy is the process of heating and cooling indoor spaces by transferring the hot or cold energy stored underground. The temperature 6ft below the earth’s surface is constant at 50°F or 10°C throughout the year, and geothermal energy uses the sub-surface temperature of the earth to provide heating and cooling.
Geothermal systems move this energy using a heat pump to move an environmentally-friendly fluid through a series of buried pipes, and then distributing it throughout the building. Very little electricity is used to move the fluid and drive the heat pump for the production of cool air and no fuel is burnt to produce heat.
A bonus of the geothermal system is the production of hot water as a by-product, which can be used for multiple purposes.
Geothermal Heat Pump: A geothermal heat pump is a piece of equipment that uses ground or ground water to source thermal energy to heat a building or as a thermal energy sink to cool a building. Ground source heat pumps are also known as geothermal heat pumps.
