200L Solar Geyser Systems. Thermosiphon 

The transfer between tank and collector is governed by gravity (hot water density is lower than cold water density). Instead of a pump, the pressure differential between hot and cold is used as propulsion energy. This is the “thermosiphon principle”. In order to operate, the collector (heat generator) must be located below the tank (heat consumer).The heat transfer medium is heated inside the solar collector. The hot liquid in the collector below is lighter than the cold liquid in the tank above the collector. As soon as the lighter hot liquid rises, gravity circulation starts.Inside the cylinder, the heated medium transfers its heat to the stored domestic hot water and then, once cooled, falls back to the lowest point in the collector circuit.
