Non Pressurized Solar Water Heaters
(Thermosiphon)

 
Thermosiphon solar water heater relies on the natural circulation of water between the collector and the tank or heat exchanger. As water in the vacuum tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system.
These systems are reliable and relatively inexpensive but require careful handling during installation because the water tanks are heavy.

 
In a thermosiphon Solar Water Heater, household water or a heat-transfer fluid moves through the system without pumps. This kind of passive system has advantage that electricity outage and electric pump breakdown is little possible to happen. Generally speaking, the passive systems are more reliable, easier to maintain, and possibly longer lasting than active systems. Passive systems are often less expensive than active systems, but are also generally less efficient due to slower water flow rates through the system.







 
               IDS-GS-58/1800               
  
 
The solar water heater IDS-GS-58/1800 Consists of three main parts:

   1- Solar Collector: Is the solar double vacuum tube which is made of borosilicate glass and has the diameter
       of 58mm and the length of 1800mm


   2- Tank: It consists of inner tank which is made of food grade stainless steel SUS304-2B and is isolated by foam poly urethane with the thickness of 4.5~5.5cm, and the outer tank is
       made of galvanized steel and electrostatically painted to resist most weather conditions.

   3- Bracket: Is made of Galvanized steel which is electrostatically painted
to resist most weather conditions.
