The modernday, direct flow vacuum tube systems collect a vast amount of solar energy and thereby ensure high efficiency. The vacuum in the tubes guarantees very effective thermal insulation. There are minimal losses between the glass pipes and absorbers – and the collector is able to transform even a minimum
of sunlight into available heat.
Heat captured by the sun during the day needs to be stored for use later on. Further more, utilizing combi storage tanks like the on pictured, multiple users such as in-floor or swimming pool heating can be powered by a single source.
To complete the system, various control and pump systems are required to circulate and direct solar heated water in the most efficient way |
