Specifications

Non pressure solar hot water heater 150liter 



Working Principle

Thermosyphon solar water heater adopt simple thermal circulation, cold water heated by collector, and then hot water go up to tank, cold water in tank flow into collector, cold and hot water form a natural circulation in solar water heater, the whole tank water will be hot water gradually.
