The project

Revolution Power Installers were asked by KPP Architects of Leeds to do a feasibility study on the best possible Renewable Heat Source for one of Evans Easy space buildings at Ludlow’s Eco Business Park in Shropshire. Ludlow Eco Business Park is a partnership scheme involving South Shropshire District Council, regional development agency Advantage West Midlands and the Rural Regeneration Zone. The project has also received funding from the European Regional Development Fund. The new office units, which vary in size from 100 to 6000 sq ft, are being built to BREEAM Excellent standards – the building industry’s highest rating for environmental excellence in construction. All buildings on the site were targeted to reduce greenhouse gas emissions by 50% compared to conventional structures. For Evan’s Easy Space Buildings Revolution Power recommended the best solution was a Stiebel Eltron Ground Source Heat Pump to provide under floor heating and hot water requirements for offices and a workshop. The Stiebel Eltron Ground Source Heat Pump was a key element in achieving a BREAM Excellent Standard. By installing the GSHP a 20%+ CO² carbon saving has been achieved.

In this installation, Revolution Power drilled boreholes to insert the ground probes for the heat pump. Revolution Power contracted a specialist firm to install the under floor heating system using Uponors PEX20 system. They also used Uponors district heating system to link to the UFH for an office the other end of the building. After the boreholes and under floor heating were completed the Stiebel Eltron ground source heat pump was installed with a 700 litre buffer tank for the UFH integration and a 400 litre domestic hot water cylinder.

The main benefits of the installation include

  • Reduced heating overheads
  • 20% + CO² carbon saving
  • Easy maintenance
  • Flow temperature of up to 60 degrees
  • Mobile controlled with GSM Box
  • Achieves BREAM excellent standard
  • Extremely quiet operation
