The energy harvesting hybrid

The Minus 7 energy harvesting system is a welcome revelation within the renewable energy sector.

 

The Minus 7 hybrid energy harvester is a new addition to the renewable energy market. Mark Wozencroft, Managing Director, of Minus 7, explains the benefits of the system that provides all year round heating and hot water.

 

The Minus 7 System is made up of an endothermic roofing system, a solar energy processor and a thermal store. The endothermic ??collector plate?? is made up of roofing tiles made from a 2.5 mm thick aluminium extrusion, dressed in a hard wearing finish. These hollow tiles are filled with a heat transfer fluid made up of 70% water and 30% glycol which creates a flooded roof system. An endothermic reaction harvests heat and solar radiation from the ambient surroundings which is then processed and sent to the thermal store to be drawn off as required. The system can provide a building with all its hot water and heating needs. Designed and manufactured in the UK, it has recently been registered under the Government??s SAP (Standard Assessment Procedure) Appendix Q, from which it emerged with a Best in Industry accolade.

 

The system requires around 20m2 of collector plate tiles which would typically cover one face of an average sized house. However due to the enhanced quality of the aluminium tiles as a roofing product we would encourage users to adopt the system for their entire roof. All the required elements are available such as verge tiles, bay tiles, ridge tiles and even ice planks. The system also intelligently makes use of a bubble seal and a flipper seal, both of which are designed to keep out driving rain and high winds.

 

There are no unsightly bolt-on panels, which means that the system is visually unobtrusive and can not be readily distinguished from any other normal roof from the street. Also because it??s primarily harvesting endothermic energy it does not require a south facing roof.

 

The system is entirely autonomous, the energy harvesting system is completely separate from the house heating system and works by delivering low-grade heat to a thermal store buried in the ground external from the house. There are no other support mechanisms, such as a boiler, required. The system not only reduces the quantity of hydrocarbon required to deliver a particular thermal load but will also deliver that heat at a significantly lower unit cost (typically at 25% of the equivalent gas fired cost). This is in line with Government strategy to provide low carbon solutions and affordable warmth.

 

The Minus 7 System offers low running costs coupled with durability due to the commercial quality of build. It will last for at least 50 years and is maintenance free for its entire life. It is also incredibly economical, with control systems that endeavour to run the heat pumps as little as possible, in summer for instance they might not run at all. It is suitable for many applications from domestic and social housing right through to aeronautics, farming, commercial and leisure.

 

As energy prices continue to rise year on year the Minus 7 System offers a solution that will help users to keep their costs down whilst still providing affordable, comfortable levels of heating and hot water. In short, as far as heating technology goes the leap between what is currently available on the market and the Minus 7 system is as revolutionary as when we first transitioned from steam to combustion engines.
