Geothermal Ground Loop Installation

Drilling the borehole is only part of a successful geothermal installation. Once drilling is complete, the specified ground loop must be installed safely and in a controlled manner. Miller Drilling Contractors operates specialist hydraulic loop handling equipment to support the controlled installation of geothermal ground loops into completed boreholes.

These projects can require substantial borehole arrays providing ground source infrastructure for multiple properties or buildings.

• New-build housing
• Social housing
• Apartment developments
• Universities
• Hospitals
• Commercial campuses
• Public-sector estates
• Mixed-use developments

Our specialist drilling equipment allows different drilling techniques to be utilised according to geology, borehole specification and project requirements.

From drilling to completed ground loop

• Site mobilisation and drilling setup
• Borehole drilling
• Casing where required
• Ground loop installation
• Pressure testing
• Thermal grouting
• Borehole completion

We work to the project borehole design and specification and coordinate our drilling operation with the wider GSHP and construction teams.

Miller Drilling Contractors provides specialist commercial geothermal borehole drilling and ground loop installation for ground source heat pump projects throughout the UK. We work alongside GSHP installers, principal contractors, M&E contractors, developers, consultants and energy specialists to deliver the drilling element of commercial ground source heat pump installations.

Commercial borehole arrays

Large ground source heat pump systems can require substantial numbers of vertical boreholes. As the size of a borehole field increases, drilling productivity, site logistics, water management, drilling fluids, loop installation and coordination with the wider construction programme become increasingly important.

Our commercial drilling operation is structured around these requirements.
