green box group are leading installers of solar hot water systems in Yorkshire, Humberside and the East Midlands >
As fuel prices continue to rise, reducing your energy bills while minimising your carbon footprint has never been more appealing. In a typical house, heating hot water accounts for approximately 25% of the heating bill – the remainder being central heating. Our solar hot water systems fulfil more than half of a household’s annual hot water requirements – more in spring, summer and autumn, less in winter.
Our systems are designed with a long lifetime, have a minimal maintenance requirement and are certified to EN ISO 9001:2000. Our accredited installers operate in Yorkshire, Humberside and the East Midlands, and we provide a 3-year warranty on all of our installations.

The panel’s collector tubes convert daylight into solar heat. Once the collector has reached a temperature several degrees hotter than the hot water cylinder, an electric pump will start circulation around the system. The solar thermal heat in the collectors is then transferred to the hot water cylinder via a heat exchanger coil, in the same manner as a conventional boiler.
Our solar hot water systems use an integrated control station that monitors the temperature of both collector and cylinder to maximise the uptake of free solar energy. The control station also prevents heat stored in the hot water cylinder being pumped back through the collector panels and lost, and has a number of safety features to prevent the system overheating. Our trained installers will show you how simple the system is to use.
evacuated tube solar collector - consisting of 1, 2 or 3 panels, designed to be fixed less than 200mm above roof line
circulatory system - electric pumps and pipes containing heat transfer medium (water and antifreeze mixture)
control unit and safety features - including expansion tank to control overheating
New 200 litre stainless steel cylinders have twin coil heat exchangers, plus a back up electric immersion heater where required. The heat exchange coil for the solar water heating system sits below that of the conventional heating system in your cylinder, meaning that the solar hot water system will provide your primary water-heating source, and only utilise your conventional boiler as a top up in cold weather.
