The Minus7 system is a comprehensive, hybrid solar thermal and integrated solar PV system that provides an all in one heating and power energy solution across a range of property types from homes and flats through to pools and even garages. It is delivered by dedicated design and installation teams along with a full aftercare service; our team of technicians and engineers provide support, advice and back up to ensure that the System can be integrated seamlessly into your build.

Every installation is carefully optimised for each particular property, and is suitable for old style renovations as well as brand new builds.

The System is engineered to work most efficiently in the cool, temperate, high humidity conditions of the British climate, and orientation is not critical to the efficient operation of the System.

As the responsive Tileplanks form the roof, the project becomes very much simpler, with all parts of the roof and heating system carefully configured to suit your build. The roof can usually be fitted and made watertight in less than 2 days, with the remainder of the System taking a further 3 to 5 days to install, test and commission.

The Minus7 Endothermic System is listed in the NCM (SAP) database within Appendix Q under ‘Solar assisted heat pumps’, and has been independently tested at the Building Research Establishment to EN14511 part 3:2007 (heat pumps) and EN12975-2:2006 (solar thermal).  Our technology is accredited under the Microgeneration Certification Scheme (ETRS – Minus7) and Minus7 is a registered MCS Installer.  Minus7 are also members of REAL – Renewable Energy Assurance Ltd.

Financial Benefits

The Minus7 Endothermic System provides all the domestic hot water and heating for your property at approximately 50% of the cost of running a condensing gas boiler. It is designed to run extremely efficiently and for a considerable period of time – on average twice as long as a conventional boiler.

A two year warranty for parts and labour is included as standard; an upgrade to 10 years is available at minimal cost.

Environmental Benefits

Behind the Minus7 System there is a massive bank of industry knowledge, technical and practical expertise, and a wholehearted commitment to ethical harvesting of renewable energy.

Primarily, the Minus7 System harvests renewable thermal and solar energy. It offers a reduction of up to 50% of CO2 emissions compared to an equivalent condensing gas boiler, and there is no requirement for any additional equipment or systems to achieve this. The System is ideally suited to work at the lower temperatures required by under floor distribution systems as well as high output, low temperature radiators such as JAGA.

The Endothermic Roof has an expected life of 35 years to first maintenance, and after many further years of active service, it can be recycled at the end of the life of the building; a fully responsible, pioneering approach to energy supply.
