  Working Principle:  Solar Water Heater is open to air and relies on water natural circulation. High borosilicate  all glass vacuum tube has selective absorbing surface, absorptivity above 0.93 and emissivity  below 0.05, it enables vacuum tubes to have good absorb and transmit performance. When  water in vacuum tube is heated, it rises naturally into storage tank,while cold water in storage tank flows back to vacuum tubes. The tank must be located above the absorber tubes and the whole system need to be installed on the roof and faces to the sun.     Advantages: 1. It operated completely automatic if connect with intelligent controller. 2. Simple structure, easy plug-in installation, can be installed both on flat and  inclined roof, and can be used with an auxiliary electrical heater as to provide  hot water without sunshine. 3. Superior heat preservation ensured by one-off molding polyurethane foam with  thickness 65mm. Can keep warm efficiently for 3 days 4. Stable and reliable performance, well wind resistance. 5. Meet the mankind healthy bath standard: The material of inner tank is SUS304-2B  stainless steel sheet; The silica gel ring sealing has a long life against the erosion and it  is not harmful to health.
