Solar controllers as temperature differential controllers

for solar thermal systems

Solar thermal systems convert incident solar irradiation into heat that is used to heat domestic hot water or for additional heating. The solar irradiation is converted into heat in the collector whose main component is a selectively-coated absorber. The heat is pumped via a closed piping system, the solar circuit, from the collector to the storage tank. The solar energy system not only provides hot water in the summer and in transitional periods, but can even provide some in winter. A frost-resistant mixture of water and glycol is used to prevent the heat-transfer fluid freezing in the solar circuit. The mature, high-performance technology from Steca guarantees that a large proportion of the hot water requirement can be provided for by using solar energy.
