    Non pressurized solar water heater

    Non pressurized solar water heater

    Solar water heater is water heated by the use of solar energy. Its system may use electricity for pumping the fluid, and have a reservoir or tank for heat storage and subsequent use.


    Solar collector is a solar collector designed to collect heat by absorbing sunlight. The term is applied to solar hot water panels, but may also be used to denote more complex installations such as solar parabolic, solar trough and solar towers.





    Key points
    Inner tank: stainless steel SUS304-0.5mm
    Vacuum tube: QB-AL-N/AL-47-1500/58-1800
    Outer tank: painted steel-0.4mm/aluminum-zinc coated steel-0.45mm/stainless steel SUS304
    Insulation: polyurethane
    Frame: coated galvanized steel-1.5mm/stainless steel SUS430-1.5mm   


    Principle


    The working principle of the this one which has a small tank on top is similar as the one compact non-pressured solar water heater without the assistant tank,it is also open to air and relies naturally into storge tank,while cold water in storge tank flows back to vacuum tubes.The tank must be located above the absorber tubes and the whole system need to be installed on the roof and face to the sun.The mainly different of this one which has a small tank on the top with the one without the small tank is the small tank can fill full the big water tank storge if there is no enough water inside of the big tank.


    The vacuum tubes trap incident sun rays, and convert it to heat inside the inner tube. Water, now being heated its temperature rises, density changes, and hot water sections rise through the tube to the top of the tank, while cold water from the bottom of tank replaces it in the tube, to start the cycle again. This natural cycling of water driven by temperature difference keeps water hot when stored in an insulated tank.                                                                    








    The solar water heater tank is a non-pressurized tank, and has an opening to the ambient atmosphere. Solar water heater tank should always be filled with water to avoid damage caused by dry high temperature working conditions. The stainless steel our use belong to food grade, and SUS 304 & SUS 316 have better corrosion resistance.    




    Thermal Performance


    The system passes over thermal performance test according to EN12976-2:2006-chapter 5.8, parts of the test conditions are listed below:
