solar water heater

Working principle:

The series employs the natural convection phenomenon called “thermosyphon”.

The evacuated tubes convert solar energy into heat energy and transfers heat to water.

The lighter hot water in tubes rises to the storage tank, while the cold water at the bottom of the tank flows into the tubes, creating continuous circulation.

The convection flow will continue as long as the sun is heating the collector.
