Non pressure evacuated tube solar water heater with 20liter horizontal feeder tank

Working principle:

It adopts simple thermosyphon circulation. Cold water heated by solar vacuum tubes, then hot water goes up to water tank. Cold water and hot water forms a nature circulation between solar vacuum tubes and water tank. Then whole tank water will be hot gradually.
