‘Pioneering Classroom of the future’
Kensa Heat Pumps feature in this ‘Class of the Future’ alongside solar panels and rain water harvesting.

Norfolk County Council chose Hevingham School as the showcase site for its 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.
Two metre deep trenches were dug to hold the Slinkies, then backfilled to restore the playing field for normal school activities.
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.
