The Minus 7 Hybrid Energy Harvesting System is an innovative renewable energy system that provides hot water and heating for homes using endothermic roof tile planks, a solar energy processor, a water to water heat pump, heat transfer units and a thermal store. The system is classified as a solar-assisted heat pump technology and the NCM (SAP) identifier for the product is Minus 7 SEP3G10 1/2/3.
It is designed to keep a five bed house at a comfortable temperature of at least 21°C even in the worst case scenario of mid-winter. However the system is capable of servicing up to three dwellings at once making it highly suitable for housing associations.
Managing Director, Mark Wozencroft says:
“This will be the third year for Minus 7 exhibiting at the Ecobuild show. Response has always been very positive. In recent years many visitors commented that it was the best roofing product that they had seen at the show and noted the very high standard of engineering, choice of components and finish.”
Several elements of the system will be available for visitors to inspect including the solar energy processor, the heat transfer unit and the endothermic tile planks.
Minus 7 is exhibiting at Ecobuild, stand N2100, 3rd – 5th March 2014, at ExCeL, London.
