Product Description
Open-loop systems are simply and fast way of water heating. They are best suited to warm climate regions because of operating directly with potable water. Open-loop systems are not recommended in regions where water quality is not good enough.
How It Works
It adopts the water-water circulation type. Heat adsorption membrane on the flat plate absorbs the solar heat to heat the water in the heat collector directly. deliver the heated water to the upper part of hot water storage tank via circulation pipe and unheated cold water in the lower part flows into the flat-type heat collector as supplementation.Then cold water is heated and delivered to the hot water storage tank.The circulation of water repeats till all water in the water tank is heated to the specified temperature.

The valve will be opened at the set temperature(99℃) and pressure(7bar) to protect the water tank.
Enamel Water Tank Brings You Healthier Water Quality
"Baosteel" special enamel steel plate & "Ferro" enamel powder
Integration of world advanced rolling,welding,roller enameling technology
Perfect enamel adhesion protect water tank from corrosion
Pass 280,000 times pulse testing under 0.9Mpa pressure
√ Inner release: when the pressure in the tank is 0.015Mpa bigger than inlet pressure, there is little water released to inlet pipe.
√ Outer release: when the pressure in the tank is more than 0.75 Mpa(if the pressure of the valve is 0.7Mpa±0.05Mpa), the water will come out from the drain pipe to protect the tank.
√ Manual release: if you want to drain out all water in the tank, you can take out the screw and pull out the plastic handle to 90 degree, then the water will come out.
√ Anti-reverse: the vavle is one way, it can prevent much water flowing back to inlet pipe.
