Welsh roots. Practical capability at every scale.
Thermal Earth is based in Wales and has grown by bringing together disciplines that heat-pump projects often split between different suppliers.
Today our core design, borehole drilling and installation capability sits within Thermal Earth. That joined-up approach helps the same team carry decisions from early feasibility through commissioning and into ongoing care.
Our work spans family homes, housing developments, schools, apartments, offices, factories and specialist sites. The technology changes with the project; the responsibility to design and deliver it properly does not.
MasterTherm and Ariston are our primary heat-pump partners. ACOND is also available where its equipment suits the project, alongside supporting system brands including Altecnic, Belimo, MultiQ, Joule and REHAU.
