The illustration shows a typical Active Solar Heating system layout. An electronic controller constantly compares the temperature of the solar collectors with the temperature of the water in the cylinder.
Whenever the collectors are hotter than the cylinder, the controller switches on the system's circulating pump. A mixture of antifreeze and water is then circulated through the collectors and the cylinder's heat exchanger, heating the cylinder in just the same way as a central heating boiler.
