In a world progressively moving towards more eco-friendly solutions, ground-source heat pumps (GSHPs) systems are a key component. Drilcorp is leading the way by providing ground source geothermal borehole drilling and geotechnical exploration services to aid the installation of these systems.
As experts in providing boreholes for this technology, we’re here to give you a brief overview on GSHP systems, including their role, their function and their benefits.
A ground source heat pump (GSHP) system is a highly efficient (COP 3 – 4), heat transfer system that is used for the climate control of buildings both commercial and domestic.
On the cooling cycle, heat is removed from a building and deposited in the earth leaving the building pleasantly cool.
On the heating cycle, heat is collected from the earth and transferred into a building creating a comfortable living temperature. Hot water is also produced by the system.
There are three main components to a GSHP system:
GSHPs can provide three to four units of heat for every unit of electricity they use, making them incredibly energy-efficient (COP 3 – 4.)
Because they are energy efficient, they produce less carbon.
If your property isn’t connected to the gas grid, a GSHP can be an excellent heating solution. Government environment policy is aiming for the removal of gas boilers.
For closed loop systems, boreholes are the drilled for the installation of a ground loop. These small diameter boreholes can be drilled to various depths, depending on the size of the heat pump system and the ground conditions.
For open systems, larger diameter boreholes are required. The borehole where water is to be extracted is essentially a water well. A submersible pump is installed to pump groundwater from the borehole and through the heat pump where heat transfer takes place. The water then continues on its way to a second borehole where it is reinjected into the earth.
Drilcorp is also thrilled to announce our new Conrad Combi 300 drilling rig, designed to facilitate closed-loop ground source drilling. Equipped with a fully automatic rod loading system. This machine is perfect for any GSHP installers looking to undertake multiple closed loop projects. This highly advanced machine is also versatile, capable of constructing large diameter open loop boreholes and commercial water wells.
