Ground Source Drilling

Usually, you do not need planning permission for GSHP boreholes.

The beauty of the geothermal borehole drilling process is that it can be carried out almost anywhere. No matter if you want a ground source pump in your garden to heat your home or somewhere on your premises as an industrial business owner, it’s likely that we can install a geothermal borehole for you without a problem.

The depth of a geothermal borehole depends on the site, including the available space and the square footage that the system needs to heat/cool, and the type of ground source heat loop. For example, horizontal loops are relatively shallow, installed about 1.2m below the ground. They also cover a greater area of land, requiring at least 400-600m per maximum loop length.

On the other hand, vertical GHSP boreholes go deeper and take up less horizontal space. They can be 100-200m deep (around 330-650ft), but vertical borehole drilling usually only goes around 250-450ft underground. If you want to convert an existing water borehole, this will probably not be deep enough, requiring further drilling and construction work to be suitable for a geothermal loop.

Since the maximum depth and appropriate loop sizes vary from project to project, we must carry out initial assessments to evaluate the efficiency of geothermal drilling in the specific area. We will then discuss the drilling possibilities to determine whether this will suit your needs, before any decisions are made or any further work is performed.

The cost of geothermal borehole drilling and ground source heat pump installation is proportional to the depth, materials, and overall size and heating capacity of the specific system. This is why it’s necessary to carry out a geothermal survey to assess the thermal properties of the ground before doing any drilling, which can determine whether the investment would be worthwhile or not.

The larger the system, and the more excavation required to install it, the higher the costs will be. Similarly, the larger the output and the more properties it powers, the lower the installation and operational costs for each household. Ground source heat pumps are extremely energy efficient, producing several times more energy than the pump requires to run.

This means you could drastically reduce your mains fuel bills, eventually paying off the initial investment costs over time. You’ll also lower your carbon emissions, potentially making you eligible for the UK government’s Renewable Heat Incentive (RHI) scheme. You could receive RHI payments totalling a few thousand pounds per year, based on the amount of ‘green’ energy you generate.

Ground source heat pump loops are incredibly durable, with lifespans ranging from 20 to 50 years or more.

Geothermal drilling encompasses a wide range of tasks, from small-scale to large-scale projects. At Teckna Group, our experienced professionals possess the expertise and industry knowledge to conduct drilling operations safely and efficiently.
