Thermosiphon water circulation
Webb26 maj 2010 · This continuous natural circulation of the water through the collector and tank heats the tank water over time. Sun and gravity take care of the circulating the water, so no pump is needed. Control is automatic, … WebbHowever, circulation is provided by the thermosyphoning principle: The hot water storage tank is located higher than the solar collector and circulation flow is induced when the coldest water in the bottom of the storage tank falls by gravity through a circulation line into the bottom of the solar collector panel, where it is heated and rises.
