The non-pressure vacuum tube solar water heater operates as an open loop thermosyphon system. The vacuum tubes absorb solar energy and convert it into heat. Based on the thermosyphon principle, heated water in the tubes rises into the tank, while colder water in the tank descends into the tubes. This continuous natural circulation heats the entire water volume efficiently without the need for pumps.
