Low temperature heat from the natural environment - in this case the earth - is collected via a closed loop system.

Normally installed by our experienced engineers within vertical boreholes lined with heat conductive grout for optimum performance. A heat pump linked to an electrically powered heat condensor within an evaporation and condensation cycle raises water temperature within the circuit to meet your hot water and heating requirements.

The system is suitable for underfloor heating, radiators or air fans in addition to providing a hot water supply.

With the cost of fossil fuels constantly rising, and global warming posing an ever increasing threat to our future, ground source heating must represent a sound investment.

The images on this page show the construction and some components of a ground source heating system.

A correctly installed closed-loop heat collector within a vertical borehole - typically in excess of 100m depth - will guarantee a constant heat return, regardless of season, weather or the amount of sunshine available.
