47/1500mm 200L Color steel low pressure vacuum tubes solar water
heater for house use
Non-pressure vacuum tube solar water heater is an open loop and
thermosyphon system. Tubes with special absorptive coating
absorbing the sun energy to be heat energy to heating water in
tube. Whole system works like the way :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.
Our system design with assistant tank that would filling water
automatically ,no need to worry the water overflow.

Domestic hot water for shower, washing
1. Advanced welding technology to make sure leakage free.
2.Non-pressurized solar water heater is a most economical type
solar system with high efficiency at the same time. Working by
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 to feeding
water automatically ,save the time of human being.
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: high foam density around 43kg/m3 to 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
