Heat from sunlight
The sun's rays hit the solar collectors on the roof. They heat the circulating solar fluid, which is then transported to the solar storage cylinder. In the storage cylinder, the heat is transmitted to the drinking water and also to the heating circuit water if required. All components feature tried-and-tested series technology. Solar thermal systems can easily be incorporated in an existing system with central hot water supply at any time, independently of a new build or renovation.
Domestic hot water and auxiliary heating
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, four collectors and a 600 litre storage cylinder are required for the same size household.
