Low Pressure Solar Water Heater :
1) Energy Saving with High Efficiency
2) Nature Circulation , easily to install and operate
3) long lifespan of over 12 years
4) certification of CE , ISO , Solar Keymark ,TUV ...
Mainly Components and Funtions :
1) Vacuum tube: Hail-resisting borosilicate glass with high-tech selective coating ensures an efficient solar collecting,
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: Stainless steel shell is much more durable and super in anti-erosion aspect, much more durable even to ocean coast weather.
4) Insulation Layer: Density polyurethane integrated foam-forming with twice slaking treatment, preserves hot water constantly as long as 70~80 hours.
5) Supporting Bracket: Aluminum alloy plate with a good weight bearing and high wind resistance design
(140 km/hr), super mechanical performance and especially corrosion resistance, easy installation.
6)Accessories: Stainless bolts & nuts, water-proof silicon rubber, anti-aging dustproof rubber seal, plastic pipe holder and ventilating cap to ensure their lives as long as other parts of the system
Optional Devices :
1) Assistant tank : to automatically feed tap water into storage tank to keep it sufficient always
Electrical heater: as an auxiliary heating element in case of raining or snowing days so as to ensure a continous hot water supply
2)Intelligent controller : automatically controls water refill and startup of auxiliary heating device, more intelligent operation
3)Booster Pump: a choice for those area without tap water or with a unstable water supply
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
