Integrated Non-Pressure anti-pollution  PVDF coating Solar water heaters system 

Non Pressure Solar water heater system is the most economic solar water heater which work stable and no need any maintenance. It must be installed on the top, such as roof, to get enough hot water flow pressure by the gravity.

  3. Working Principle:      

 It is the simplest one, the tube and tank are linked together, the working principle is like this: the vacuum tubes collect the sunshine and make the water in the tube to be hot, and then the cold water in tank will circulate with water in tank automatically from time to time. This is the simplest and normal model, but very efficient. In summer, the water temperature can reach up to 95 degree, nearly boiling.

The design of this type is easy operate. The assistant tank is used to fill the cold water automatically. The design is scientific and reasonable, it could always provide hot water.
