How Solar Water Heater works:
Solar Water Heater relies on warm water rising, a phenomenon known as natural convection, to circulate water through the evacuated glass tube collector and to the tank. Hot water storage tank is located above the absorber evacuated glass tubes. As water in the absorber heats, it becomes lighter and naturally rises into the tank above. Meanwhile, cooler water in the tank flows downwards into the absorber, thus causing circulation throughout the system.

Descriptions:
1.stainless steel 304-2B for inner and outer tank,longer use life.
2.cost no electricity when sunshine is good enough,electrical heater as back-up for solar water heater when bad weather.
3.3 layers vacuum heat colected tube for the solar water heater,more efficient; purple golden,looks nice.
4.non-pressure solar water heater can be used in area lower than -5 °C,more colder,heat pipe as alternative.
5. past CE,CCC,ISO 9001 test.
