Ground source heat extraction

Borehole heat exchangers and distribution pipework

We specialise in products for the ‘out of building’ elements of ground source heat pump installations, including borehole heat exchangers, manifolds, manifold chambers, distribution pipework and grouts & sands.

Our unique industry-leading Thermo-Loops® are available in 25, 32, 40, 45 and 50mm diameters and have rapidly become the product of choice for the latest geothermal projects.

They are available as single or double loops and are made from virgin grade PE100-RC polyethylene (PE). They meet all GSHPA standards and each Thermo-Loop® has its own unique serial number and pressure test certificate.

Our ground source geothermal products set the benchmark for quality and performance and are designed to the very latest VDI 4640 standard.
