There is a misconception that solar energy only works when the sun is shining and hence solar power is unsuitable for the UK climate. The Manchester Renewable Energy third-generation solar water heating system works on a light absorption principle and its operation is not dependant on lengthy periods of sunshine or high temperatures. Solar diffused radiation is collected in the selective coated vacuum tubes and the heat generated is transferred to your solar cylinder. This even works on cloudy days and at temperatures as low as -28°c.

The system works by creating a solar circuit from the solar collectors on the roof to a new bespoke solar cylinder. This circuit contains a pressurised heat exchange fluid to enable high temperatures to be used.
