To heat or cool your home or office, a heat pump uses the principles of refrigeration to transfer heat from one area to another. When you need your house cool, they draw heat from the house and pump it outside. When you need your house warm, they draw heat from the outside and pump it in. No matter what kind of heat pump you have, they all basically use that system. So, knowing that, what is a ground-source heat pump?

A ground-source, or geothermal, heat pump uses the Earth as a source. More specifically, a geothermal heat pump has pipes buried a couple meters down to use either the ground or groundwater. When it needs heat it draws it from that source and when it needs a heat sink, it puts heat back. A geothermal heat pump works exactly like an air-source heat pump, but does not use the air as a source.

By far the biggest advantage with a geothermal heat pump is the high level of energy efficiency that can be achieved. No matter how hot or cold it is on the surface, the ground a few meters down generally maintains a stable temperature. This means the heat pump has a stable source with which to work and that equals increased energy efficiency. Ground water geothermal heat pumps can achieve even higher efficiencies.

The drawback to geothermal heat pumps is the fact that the unit requires some extensive digging in order to install. This increases up front costs and puts geothermal heat pumps out of the reach of some consumers. This is regrettable, since geothermal heat pumps are some of the most energy efficient home HVAC systems on the market and can actually pay back their installation costs in energy savings in 5-10 years.

So, remember, when you hear ground-source or geothermal relating to heat pumps, just remember that they’re talking about using the ground or ground water as the heat pump source and sink.
