This system of solar water heater is an "Open Circuit" non-pressure system. By the air vent valve on the top of the storage cylinder and the over flow pipe in the bottom it maintains open to the air.

  

This system uses good quality of boron silicon all-glass evacuated tubes with selective coating Al-N/Al as collector, which the heat efficiency is very high.

  

This system of solar water heater is an "Open Circuit" non-pressure system. By the air vent valve on the top of the storage cylinder and the over flow pipe in the bottom it maintains open to the air.

  

This system of solar water heater relies on a natural Principal-"Thermosiphon". In these systems the storage cylinder is separated from the collector and always located higher than the collectors.

  

This is a pressure system that the storage cylinder and heat pipes are closed mechanically. Although there are some evacuated tubes broken the solar water heater can still work normally.

  

This system uses the fluid in the copper heat pipe as heat exchanger, which the heat startup is very fast. The all-glass evacuated solar collector tubular is heated by the sun.

This is a pressure system that the storage cylinder and heat pipes are closed mechanically. Although there are some evacuated tubes broken the solar water heater can still work normally.

  

The collector is separated from the storage cylinder, which provide flexibility to design the home with the collectors on the roof and the storage cylinder on the ground level.
