solar preheat hot water heater,
instant solar water heater
250L Stainless Steel Pressurised Pre Heated Solar Water heater Heat Exchanger Feeding Tank
Mainly for family shower/bath
How to choose:
Choose the item according to the capacity, and choose the capacity according to the people quantity
in your family, one adult shower need about 50 L water.
Features and advantages:
1) The use water and the heat medium water have been closed isolation, transient heating ensure
water quality fresh and healthy.
2) Red high-quality copper coil is built-in, water is more cleaner, and water pipes is long service life
3) Cold and hot water’s temperature is adjustment, avoiding can't constant phenomenon.
4) The pressure directly comes fron the water suppler’s spray more carefree.
5) Needn’t file with water for starage tank evey day, avoiding the complicated operation.
6) The water in tank alway keeps remain, to avoid the phenomenon that thak is workig in empty
condition when you forgot field with water.
1) Copper coil as twice heat exchanger makes a pressurized and instant solar water heating system, tap water connects directly with copper coil for continuing water supply.
2) Hot water output is instant continuous and not limited by water storage tank
3) An assistant tank can be quipped for storage tank water refill and makes it a completely automatic running system
4) Instant water heating ensures more clean and convenient hot water use.
Vacuum tube: Hail-resisting borosilicate glass with high-tech single-target selective coating ensures an efficient solar collecting, tri-target vacuum tube with its patent interference coating even makes the efficiency improved by 12% and especially with a high temperature resistance (380oC).
Inner water tank: Food-grade stainless steel SUS304-2B as inner tank keeps the water clean and drinkable, together with advanced welding techniques to ensure a long lifespan ( more than 15 years).
Water tank shell: Stainless steel SUS304-2B/BA as outer shell with its super anti-erosion character could be installed in ocean coast weather.
Insulation Layer: High-density polyurethane integrated foam-forming with twice slaking treatment, preserves hot water constantly as long as 70~80 hours.
Supporting Bracket: strong stainless steel plate with a good weight bearing and wind resistance (140 km/hr), stainless steel ensures a long lifespan to acid rain, 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
One copper coil is installed inside the tank as the heat exchange. When water flows into the copper coil, it absorbs the heat of the water in the tank via the copper coil, change to hot water.
