Solar thermal energy systems function.

Solar thermal is the collection, storage, and use of heat from sunshine to make hot water. Solar stations and control units activate circulation when temperature at collector higher than at solar storage cylinder. A pump transfers heated circulation solar fluid from collectors to solar storage cylinder. Heated water from solar storage cylinder can be used like hot water or for heating system. Cooled solar fluid returns to collector and circulation starts again.

A solar thermal system for domestic hot water covers the entire heating requirement for your household when the heating is switched off. There is usually no need to switch on the heating during this time, which extends the life of the boiler. For a four-person household you only need two collectors and a 300 litre storage cylinder for domestic hot water.

With a system for auxiliary heating you can double the amount of energy generated. For example, six collectors and a 600 litre storage cylinder are required for the same size household.
