Ground source heat pumps take advantage of the relative consistency of temperatures below ground throughout the seasons, ensuring a predictable source of heat.
Ground source heat pumps extract latent heat from below ground, either from soil, rock or water. This can be done using either an open or a closed loop system. Open loop systems extract water from the ground, usually an aquifer, drawing it up then extracting the heat from the water before returning it to the aquifer. Closed loop systems use a refrigerant contained within buried pipes (known as slinkies or coil collectors) that absorb the heat from the ground or water its submerged within.
Ground source heat pumps require either a large area of land to lay out the ground array of slinkies / coil collectors, or ground suitable to drill a borehole up to 100m deep. If this is possible then ground source heat pumps can be the most efficient type of heat pump to run, however they can be more expensive to install due to the ground works required. We can discuss the most suitable option for your project.
