Closed Loop Geothermal

Vertical closed loop systems:

These incorporate one or more boreholes with a single U-shaped high-density polyethylene (HDPE) plastic pipe loop that circulates water with an antifreeze, usually brine.

The finished borehole is sealed with special heat-conductive grout from top to bottom.

The green energy solution extracts heat from the borehole and delivers heat to the heat pump.

Heat is extracted from the water to heat your business premises or home, before the water is returned to the ground.

Horizontal closed loop systems:

Horizontal closed loop geothermal boreholes are a type of geothermal energy system that uses the heat stored in the ground to heat and cool buildings. The system consists of a series of plastic pipes that are buried in trenches several feet below the ground surface.

The pipes are filled with a water and antifreeze mixture, which circulates through the system and transfers heat from the ground to the building and vice versa.

Horizontal closed loop geothermal boreholes are a good option for sites where there is limited space for vertical boreholes. They are also less expensive to install than vertical boreholes.

However, horizontal closed loop geothermal boreholes require more land area than vertical boreholes.
