4 models; 102 different colours.
Heating and hot water is controlled via conventional thermostats and timers
The Basic Model provides a pre-warmed supply of water to feed into an immersion cylinder or other similar water heater.
The Standard Model provides an instant supply of hot water to your taps at 40 – 45°C. The hot water passes through a UV Purifier to kill bacteria
The Plus Model allows for the addition of an extra source of heat; for example a back boiler, heat recovery or similar.
The award-winning Mini-District Model provides heating and hot water to numerous buildings e.g. terraced houses; low rise apartments.
The Minus7 System is optimised to absorb the energy needed to provide comfortable heating and hot water from even low ambient temperatures, and therefore needs a large capacity for energy storage.
The System needs two thermal stores: the hot store is warmer, contains water and is the thermal energy source for the building; the cold store is cooler, contains a mixture of 30% concentration by volume ethylene-glycol based anti-freeze and is the thermal energy source for the water-to-water heat-pump.
They are both purpose-built tanks with 200mm of insulation on all surfaces. The size and number of stores needed depends on the scope of the project, but they can be sited in various places for least impact; such as in the foundations of the building, in an outhouse or garage, or partially buried in the garden, or under a patio.
Product and Installation quality is of paramount importance to Minus7. The company has a team of trained roofers, plumbers and electricians. All have the required quality certifications to sign off the technology for building regulations and government energy subsidies.
There is no need to service gas boilers with a Minus7 system, there are also minimal operational and minimal maintenance costs. Each system is sold with a full maintenance and support package, which sits alongside the energy price/delivery performance guarantee for the duration of the contract. Minus7 guarantees the amount of energy delivered to the building.
All Minus7 Systems are fitted with remote data loggers before they leave the factory. This enables Minus7 to remotely monitor the performance of each system in the field and rapidly respond to any issues that arise.
