200L High Powered Rooftop Stainless Steel Coil Pre Heated Solar Water Heater with Feeding Tank
1.I t takes the advantage of the tap water’s pressure.
2. Completely automatic operation.
3. The water can be heated rapidly.
4. Use the copper coil as the heat exchanger, simply install and use.
5. No risk for corrosion or scale deposit, best option for inferiority water area.
6. Easy to install for flat roof and pitched roof, auxiliary heating by electrical heater.
7. High pressure polyurethane foaming with thickness 55mm.
Working principle:
The vacuum tubes absorb the sunlight and turn it into the heat energy, heating the water in the tubes. Depend on the thermosiphon principle, the hot water from the tubes goes into water tank, while the cold water from the tank goes down to the tubes.
People do not use the water from the water tank directly. The cold water comes into the copper exchanger, be heated, then goes out from other side for people use.
1: Water inlet
2: Water outlet
3: Air vent
4: Electrical heater
5: Drain vent
6: Over flow vent
Feature:
1. Glass vacuum tube solar collector, high temperature, antifreeze, vacuum insulation.
2. Food-grade stainless-steel SUS304 2B inner tank, full-automatic welding technology, under the protection of magnesium rod, it can increase of service life.
3. High pressure polyurethane foaming insulation, as the prefect density and the thermal conductivity coefficient is small, so it can provide effective heat preservation
4. The outer tank adopt color steel plate, and it has good double anti-corrosion function.
5. The assistant tank can supply water automatically so that the water in the tank can always be full, it not only can save time but also very convenience.
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
