Ground Source Heat Pumps

Efficiently heat you home and produce hot water all year by harvesting the Earth's energy

RenEnergy are MCS (Microgeneration Certification Scheme) approved installers for all ground source heat pumps.

Viessmann and Stiebel Eltron equipment is of a very high quality, it is very reliable and covers a wide range of customer requirements.

How they work
Ground source heat pumps are electrically powered and extract low grade energy from the ground using horizontally laid pipe at a depth of 1.5 to 1.8m or vertical boreholes. Water flows through these pipes and the heat absorbed,from the ground (only a few degrees), is exchanged through a highly efficient compressor inside the heat pump unit.

The energy imparted by the ground and compressor allows temperatures in your home heating or hot water circuits to reach up to a temperature of 55 degrees celcius.

Higher temperatures are achieved by using an in-built electric immersion heater.

Technology efficiency and payback
Correctly designed ground source heat pump systems deliver 5 units of useful heat energy for every 1 unit of electricity used.

With a payback period of 8 to 12 years depending on installation details,cost savings over oil and LPG heating systems can be considerable.
