Description

The basic non-pressure system SWH 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’s rays 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 air vent and the overflow pope is open to the air.
 
All the storage tanks are tested before leaving with tested pressure of 0.*5MPa (0.5bar). But the
operation pressure should be 0 MPa. The daily efficiency is over or equal to *0 % normally and *2%
in winter. We welds the inner tank by high-frequency ring or argon arc techniques
