Geothermal drilling systems make up an exciting and environmentally friendly way to both heat and cool buildings. Whether commercial or domestic, by using the ground's natural heat capacity and relatively constant temperature significant cost and environmental savings can be made.

In summer, excess heat can be dumped into the ground, and in winter, the warmer ground can be used to provide base level heating. Boreholes can be drilled to various depths dependent on the ground strata.

You can be assured should any difficulties arise, or you have a large project that needs expert knowledge then Heacol Ltd are the team you need.


INSTALLATIONS

Once the boreholes are drilled to the required depth then the geothermal loops are installed. We install 25 mm geothermal loops; the boreholes are then filled with thermally enhanced grout to maximise heat transfer the boreholes are then sealed to prevent contamination of the ground water from any surface pollutants that may be present. The thermal grout acts as a conductor between the earth's heat and the fluid in the pipework which improves the performance of the ground loop.

PRESSURE TESTING AND INSTALLING TO THE GROUND SOURCE HEAT PUMP

We pressure test all the geothermal loops before installation to ensure a leak free installation. We use hydraulic pressure tests to check the loops, the vertical ground loops are then connected to a manifold inside the manifold chamber forming a closed loop system; next the pipe work is installed to the Ground Source Heat Pump.

WHAT IS GEOTHERMAL HEATING AND COOLING?

Geothermal systems can be used to heat or cool domestic or commercial buildings. The loops that are installed either vertically down a vertically drilled borehole or horizontally in a trench in a field that is at least 1.2 meters in depth have water or other fluids flowing through them continuously. The natural heat in the earth heats the fluid in the pipe and this is then transferred to the building through the Ground Source Heat Pump and heating system. For cooling the heat is picked up by the liquid in the heating/ cooling system in the building and transferred back to the earth through the ground source heat pump.
