The basic non-pressure system solar water heater is a passive system, which relies on a natural principle-Thermosiphon. There is water in evacuated tubes and free to flow into tanks. When the water in tubes is heated
by sun' ray firstly, this makes water in the tubes lighter.therefore the cold water in the tank move downwards and
hotter water move upside into the tank. It is an open circuit since the aair vent and the overflow pope is open to the air.
All the storage tanks are tested before leaving with tested pressure of 0.05***(0.5bar).but the operation pressure should be 0***. The daily efficiency is over or equal to 50% normally and 42%in water. We welds the inner tank by high-frequency ring or argon arc techniques.
