C21t uses solar energy to heat water for washing, bathing and heating. As part of The C21 family, it is an ?integrated tile?, which replaces four conventional roof tiles and fixes to standard roofing battens using normal fixing screws. Each tile uses push-fit connectors to plug in to the next tile and the system is plumbed in to the existing hot water system by a regular plumber. An electronic controller constantly compares the temperature of the solar thermal tiles with the temperature of the water inside the cylinder.Whenever the tiles are hotter than the cylinder, the controller switches on the system?s circulating pump. A mixture of anti freeze and water is circulated through the collectors and the cylinder?s heat exchanger, heating the cylinder in just the same way as a regular boiler but without burning fossil fuels.
