Kensa Compact heat pump for Hevingham School

Kensa Compact heat pump for Hevingham School

Kensa has supplied a 20kW Compact heat pump for Hevingham School in Norfolk, the site of Norfolk County Council's Classroom Of The Future. The low energy building design is highly insulated with a “wet” underfloor heating system throughout.

The Kensa 20kW Compact heat pump connects to the underfloor for space heating only with provision of hot water supported by solar panels and the water supplied primarily by a rainwater recovery system. Ground arrays, ‘Slinky’ pipe coils, were buried underground to draw the heat energy transferring this to the heat pump via a manifold on the outside of the plant room. The Slinkies are buried under the school playing field in four trenches, each fifty metres long.

This was the first British application using a heat pump dedicated Scroll compressor, the latest technology developed by Copeland. As pioneers in heat pump design and manufacture, Kensa invest in proven components to maximise energy efficiency. The compressor is capable of working over a wider operating envelope than traditional compressors and is between 8% and 12% more efficient.
