Ground Source Heat Pump

Ground source heat pumps extract heat from the ground by circulating fluid through buried pipes in horizontal trenches or vertical boreholes. They concentrate heat by using a vapour compression cycle, and they transfer heat into buildings to provide heating and hot water without burning fossil fuels.

A well designed GSHP system provides the lowest running cost of any heating system – because it uses a small amount of electricity to transfer a large amount of naturally occurring heat from the ground into your building.

A GSHP can also be reversed to provide cooling in the summer. This will both release heat from the building and recharge the ground with heat - which improves the performance of the heat pump the following winter.
