Knowledge about Solar Energy Water Heater description: 

Non-pressurized solar water heater is such 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 for shower use. A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the auxiliary heating device and water refill at the same time. 


Vacuum tube: Hail-resisting 3.3 borosilicate glass with high-tech single-target 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 380oC high temperature resistantce without peeling off the coating layer.


Inner water tank: Food-grade stainless steel SUS304-2B or 316L as inner tank keeps the water clean and drinkable, together with advanced argon arc welding technics to ensure a long lifespan (more than 15 years).


Water tank shell: Stainless steel shell SUS304 or galvanized steel with special plastic spraying  is much more durable and super in chemical resistance, much more durable even to ocean coast weather.


Insulation Layer: High-density polyurethane integrated foam-forming with twice slaking treatment, preserves hot water temperature as long as 70~80 hours.


Supporting Bracket: Very strong good quality steel plate or aluminum alloy with a good weight bearing and high wind resistance design (140 km/hr), super mechanical performance and corrosion resistance ensures a long life to ocean coast, easy installation, universal bracket suitable for either flat and slope roof installation.


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:

Assistant tank,  automatically feed tap water into storage tank to keep it sufficient always

Electrical heater, as an auxiliary heating element in case of raining or cloudy days so as to ensure a continous hot water supply

Intelligent controller, automatically controls water refill and startup of auxiliary heating device, more intelligent system operation


Solar Hot Water Heater Warranty: 5 years international responsibility for integrated system exchange and 15 years for glass vacuum tube compensation due to original quality problems
