Case Study – Barn conversion, Middle Hengoed

Middle Hengoed, Kington, Herefordshire

Existing situation and objectives

Here the client wished to take advantage of the RHI scheme available, but also wanted to secure lower energy bills for years to come.


Before initial design or work commenced we carried out a survey with the client and the architect. A Heat Loss calculation was carried out along with a British Geological Survey to size the borehole depth accurately.

Two 8kW Valliant heat pumps were installed, which were then connected with three 130m boreholes. We also fitted an under floor heating system and commissioned the installation itself, connecting all elements so that they worked cohesively and efficiently together. The work was completed in 3 weeks.

Outcome and benefits

The installation of this system has eradicated a need for any fossil burning oil or gas boilers, and as a consequence the client has seen over 3 tonnes of carbon reduction per year. They were also able to claim from the RHI initiative and experienced significant reductions in energy bills as a result of them not using oil and gas.
