Ground Source Heat Pumps

Choosing a geothermal heat pump allows you to take energy from the ground to heat your home, moving heat from one place to another via a refrigeration process. The energy stored in the ground is simply extracted and transferred to the heat pump via a 150m deep borehole and can be used for heating, hot water and cooling

The benefits of changing to green energy are endless; low energy bills, comfort heating for both underfloor heating and radiators and heating, as well as providing hot water for the whole home 24/7.

Ground source heat pumps have the potential to reduce CO2 emissions from heating, cooling and hot water supply.
