250L Stainless Steel Pressurised Pre Heated Solar Water heater Heat
Exchanger Feeding Tank
Application:
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
Working Principle
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.
