Geothermal Systems

Geothermal 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.

Vertical closed loop systems

With the latest technology that Danbar Drilling Services has we can provide drilling on closed loop and open loop systems.

Closed loop systems are continuous lengths or a series of pipes buried in the ground. This type of system is used where there is little space or when the surface rocks make digging impractical or if the client wants disruption of the landscape kept to a minimum. Vertical holes 50m to 200m are bored into the ground, and then a double or single geothermal loop with a U-bend at the bottom is inserted before the borehole is backfilled. Each pipe is then connected to horizontal underground pipes that carry fluid to and from the indoor exchange unit. Less piping is required in vertical systems as the temperature is more stable further below the earth’s surface.

What is Geothermal Heating and Cooling?

Geothermal energy is heat extracted from the earth. Drilling boreholes allows for access to the earth’s natural heat, which is at a relatively constant temperature of 45-58 degrees.

Geothermal systems can be used to heat or cool domestic or commercial buildings. The loops that are installed either vertically or horizontally have water or other fluids flowing through the continuously. The natural heat in the earth heats the fluid in the pipe and is then transferred to the building. For cooling the heat is picked up by the liquid and transferred back to the earth.

Why a GSHP?

Ground source heat pumps are efficient, for every unit of electricity used it produces three to four units of heating. This not only saves energy and money but it reduces air pollution.

They are safe, no need for a boiler. So no flame, odours or carbon monoxide risks.

GSHP can be used in lots of locations, even if there is limited space. There is no outdoor equipment that can look unsightly, just a quiet, self- contained indoor unit.

They are environmentally friendly as it elimates the combustion of fossil fuels therefore reducing the emissions of greenhouse gases.
