Types of Projects

Where we’ve used our expertise to deliver borehole drilling and GSHP installation to the highest standards across all types of projects.

Commercial Buildings

Commercial GSHP systems can provide ambient heating, heating and cooling - or even industrial process heat - we work on commercial sites of all scales to deliver GSHP installation requirements as per the project design.

From the education sector, to hospitals and police stations, we deliver large-scale GSHP solutions to meet the heating and cooling needs of public buildings. .

Large Residential

Networked ground source systems are perfect for large residential buildings and apartments: our rigs and team are experienced in working at scale to drill for these larger, networked heating and cooling systems.

Our Approach

Design & Feasibility

All potential projects begin with a site visit to conduct a feasibility study and perform a high level risk assessment: we are RECC and SMAS certified. We assess the feasibility of our rig's access to the site and evaluate any conditions that will need to be taken into account with the borehole loop design. If required we then move to a heat loss assessment.

Drilling

High-quality and well-maintained equipment ensures the borehole drilling phase is ready for success. All equipment and rigs are owned in-house. We conduct daily and weekly checks as routine, with a specialist’s assessment every 500 hours of use. We pride ourselves on ensuring that we cause minimal disruption to our clients and sites.

Headerworks

We are one of the few installers in the UK to offer a comprehensive drilling service - complete with headerworks and glycol fill-up.

Heat pump installation

Onsen Energy can deliver the heat-pump install and plumbing - everything up to the termination points in the building with minimal disruption.
