China Swh-N Sereis Compact Pressure Solar Water Heater 120 150 180 200 240L

COMPACT NON-PRESSURIZED SOLAR WATER HEATER SWH-N Sereis

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.
