Solar Power (Heating Systems) |
 Use solar energy to heat water for washing, bathing and heating. Available in two different formats, the ‘Solar thermal’ can be fitted to sloping roofs or mounted on flat roofs using a specially designed framing system.The sloping roof system can be integrated into the roof, or retrofitted over conventional tiles. The integrated solution utilises a wooden backing to minimize embodied energy and improve recyclability. An electronic controller constantly compares the temperature of the water within the solar panel with that of the domestic hot water cylinder. When the Solar panel is hotter than the cylinder, the controller switches on the system’s pump. A mixture of anti freeze and water is circulated through the cylinder’s heat exchanger, heating the cylinder in just the same way as a regular boiler but without burning fossil fuels.
Features - Thermal protection - mineral wool thermal insulation
- High quality - special solar glass with minimal iron content
- Lasting finishes - powder coated aluminum cover profiles
- Discrete - matt black collector plate and frame
- There is normally no need to require planning permission for the installation of solar power though it is always worth checking with your local authorities.If you have a listed building it is unlikley that you would be allowed to attach solar panels to your roof .

Flat plate collectors are typically flat, thin boxes with a transparent cover that are mounted on rooftops facing the Sun. The Sun heats a blackened metal plate inside the box, called an absorber plate, that in turn heats fluid (air or water) running through tubes within the collector. The energy transferred to the carrier fluid, divided by the total solar energy that falls on the collector, is called the collector efficiency. Flat plate collectors are typically capable of heating carrier fluids up to 82°C (180°F). Their efficiency in making use of the available energy varies between 40 and 80 percent, depending on the type of collector.
These collectors are used for water and space heating. Homes employ collectors fixed in place on roofs. In the Northern Hemisphere, they are oriented to face true south (± 20°);For year-round applications such as providing hot water, they are tilted relative to the horizontal at an angle equal to the latitude ± 15°.
In addition to the flat plate collectors, typical hot-water and space heating systems include circulating pumps, temperature sensors, automatic controllers to activate the circulating pump, and a storage device. Either air or a liquid (water or a water-antifreeze mixture) can be used as the fluid in the solar heating system. A rock bed or a well-insulated water storage tank typically serves as an energy storage.
