vacuum tube solar water heater Working Principle: The non-pressure thermo siphon systems rely on the natural circulation of the water between solar tubes and the water tank. Thermo siphon systems (which are open loops systems) work on the principal of heat rising. The potable water enters in the bottom of the collector and rises to the tank as it warms. The advantage of this system is that solar heat is stored in a well-insulated tank, so hot water can be used at any time without the penalty of overnight losses. Moreover the insulation of the tank can protect heat during 3 days without heat loss ******************************************************************************- Inner tank: Food grade SUS**4/2B stainless steel with optional 0.*1mm, 0.*5mm, 0.*0mm, and 0.*0mm thick.
