Features description:

Compact Non-pressurized Stainless Steel calentador de agua solar 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.

A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the startup of auxiliary heating device at the same time. 


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 (380oC).


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:  Stainless steel plate SUS201-BA as outer shell is much more durable and super in anti-erosion aspect, much more durable even to ocean coast weather.


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


Supporting Bracket: Aluminum alloy as bracket with a good weight bearing and high wind resistance design (140 km/hr), super mechanical performance and corrosio resistance ensures a long life to ocean coast, easy installation, universal bracket suitable for either flat or 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, 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


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


Booster Pump, a choice for those area without tap water or with a unstable water supply


Warranty: 3 years international responsibility for integrated system and 15 years for glass vacuum tubes due to original quality problems
