|Item No.||Vaccum Tube||Tank capacity||Solar Collecting Area||Loading Quantity|
1.Vacuum tube: Hail-resisting borosilicate glass with high-tech
selective coating ensures an efficient solar collecting, tri-target
vacuum tube with its patent interference coating makes the
efficiency not only improved by 12% but also with a high
temperature resistance (380oC).
2.Inner water tank: Food-grade stainless steel SUS304-2B as inner
tank keeps the water clean and drinkable, together with advanced
welding technics to ensure it with a long lifespan (15 years).
3.Water tank shell: Imported color steel plate, with its outer
coating treatment ensures a long life even to ocean coast weather.
4.Insulation Layer: Germany-imported polyurethane integrated
foam-forming with twice slaking treatment, preserves hot water
constantly as long as 70~80 hours.
5.Supporting Bracket: Hot-DIP galvanized steel plate with a good
weight bearing and wind resistance(140 km/hr), super mechanical
performance and corrosion resistance ensures a long life to ocean
coast, easy installation, universal bracket suitable for either
flat or slope roof installation.

How non-pressurized solar water heater works
1. Non-pressurized solar water heater of all glass evacuated tube
collector integrated with storage tank, are ideal for use in houses
and other applications where cheap, reliable hot water supply is
required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are
different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becaomes
lighter and goes to the water tank, while cold water in the tank
goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will
be gradually heated.
Non-pressurized solar water heater features
1. Cheap and reliable solution, Simple structure, Easy installation
2. High efficiency
3. Withstands water pressure no more than 0.1MPa
4. Operated without any power supplying
5. Electric heater can be used as back up in rainy days
6. Hot water can be used directly, or can be used as a pre-heated
Domestic hot water for shower, washing
