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 resistantce .

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).Water tank shell: Imported color steel plate, with its outer coating treatment ensures a long life even to ocean coast weather.

3.Insulation Layer: Germany-imported polyurethane integrated foam-forming with twice slaking treatment, preserves hot water constantly as long as 70~80 hours.

4.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.

Working Theory:

Non-pressure vacuum tube solar water heater is an open loop and thermosyphon system. The vacuum tube with special absorptive coating can absorb the sun energy and transfer sun energy to heat energy. Whole system works according to the thermosyphon principle. Water in vacuum tubes is heated and then rises to top of tank. Cold water in tank goes down to the vacuum tube bottom. Water in the system will be heated as circulation keeps going on. This type of solar water heater is one of the most popular systems because of its own advantages of high efficiency,cheap price,simple Installation and free maintenance.
