How Ground Source Heat Pumps work
A Ground Source Heat Pump circulates Glycol (antifreeze) around a collector pipe, called a ground loop, which is buried in the ground. Heat from the ground is absorbed into the fluid and is then passed through a heat exchanger into the Heat Pump, where it is concentrated for use in your home or business.
The ground stays at a fairly constant temperature all year around once we reach about 1 meter under the surface, so the Heat Pump can be used throughout the year.
The length of the ground loop depends on the size of your property and the amount of heat you need. Longer loops can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.
