harvesting natural energy

Cut Your Heating and Hot Water Bill by up to 70%

The Minus 7 System comprises an endothermic roofing system, a solar energy processor and thermal store. This system can provide a building with all its hot water and heating needs using renewable energy, thereby reducing fossil fuel usage. Our system, unlike others, does not rely on unsightly bolt-on panels and does not need to face due south.

The Minus 7 System provides a solution that will guard against dramatic inflation in heating costs and provide affordable, comfortable levels of home heating throughout your life.

Our roofs are recognised by the Government’s Standard Assessment Procedure for Energy Rating of Dwellings (SAP)
