Working principle:
The series solar water heaters relies on the natural circulation of water between the collector and the tank or heat exchanger. As water in the evacuated tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the evacuated tubes, causing circulation throughout the system
