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.

Specialty: 

• 1.Economical type for most of area,common people can afford it
• 2.Simple product structure:   solar collector and water tank connected together directly, no need of pipe to connect, and no pump to push fluid
• 3.Mature technology and stable operation
• 4.Higher efficiency on photo thermal conversion.
• 5.Accessory is popular and easy maintenance
