solar water heart use the sun to heat the working fluid ( mostly water ) in the vacuum tubes. The solar collector absorb solar radiation , converts the sunlight to heat and transfers it to the water . The heated water naturally rises through the solar collector in the tank where the cooler water at the base of the tank is forced out and descends to the bottom of the collector ( thermosiphon circulation). The circulation will be interrupted when there is no solar radiation.
Solar water heater based on thermosiphon principle
