Geothermal heat pumps extract heat from water pumped from wells, making them much more efficient for both heating and cooling than standard air source heat pumps.

A geothermal heat pump works the same way as a regular heat pump or an air-sourced heat pump. We transfer heat just like they did, so that ours we're transferring heat with the ground as opposed to outside temperatures. A heat pump uses an outside temperature and a refrigerant to transfer the heat. In a cooling season, you can put your hand over that fan and you can feel the heating burning off. We use refrigerant in water, and in some case water and methanol as an anti-freezing agent. And water will flow from these part of the unit. They will go into the ground, out of the ground, into the pump and back to the unit. So we're just re-circulating water and it's -- the ground loop should last around 50 years. These ex lines got a hot water tank, we're actually will taking the heat and send it to your hot water tank, it will give you about half year hot water for free.
