1. Advanced welding technology to prevent any leaking of tank
2. Special chemical layer between inner tank and outer tank to make
sure the density of foam the same everywhere
3.Non-pressurized solar water heater is such kind of a most
economical system with high efficiency at the same time. It works
depending on the gravity of water, so it's much better to be
installed on the slope or flat roof as top as possible to get
enough hydraulic pressure.
4.A simple assistant tank can be equipped for tap water refill
automatically or with an intelligent controller to control the
start up of auxiliary heating device at the same time.
5.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).
6.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).
7.Water tank shell: Imported color steel plate, with its outer
coating treatment ensures a long life even to ocean coast weather.
8.Insulation Layer: Germany-imported polyurethane integrated
foam-forming with twice slaking treatment, preserves hot water
constantly as long as 70~80 hours.
9.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.
10. Accessories: Stainless bolts & nuts, water-proof silicon
rubber, anti-aging dust-proof rubber seal, plastic pipe holder and
ventilating cap to ensure their lives as long as other parts of the
