How Does Solar Water Heater Works : Solar Heater Tank (Cobra) is composed of two internal and external that are are made of the finest stainless steel and laser welded to ensure that no diversion of water from the tank and between them a dielectric material (Polyurethane) German-made with thickness of 50-60 mm in order to keep the hot water in the tank for a period ranging from (72-80 hours) and not being affected by the external atmosphere surrounding it.
The vaccum glass tubes are composed of two glass tubes were welded after getting rid of the vacuum between them to ensure keeping the heat.
the Inner tube has an outside layer of material (Coded Film) German-made which absorb the solar rays and is made of magnesium, chromium, nickel materials and some other metals
the External tube allow the passage of the sun rays to the inner tube and does not allow the exit of the heat due to the presence of vacuum between the tubes. Also, the external tube will always be cool.
When the water enters inside the inner tube and being heated by heat exchange theory it becomes hot after a few minutes and as a result of differing densities theory the hot water rises to the top of the tank and the cold water descends to be heated and so on.
