• Camps/Cottages
  

• Green  Houses/Industrial
  

• Out Door Showers
  

• Campings with storage tank
  

Principle

Thermo siphon Solar Water Heater works following the principle of warm water rising, a phenomenon

Known as Natural Convection, this to circulate water through the collectors and to the tank. In this type of As water in the solar tubes heats, it becomes Lighter and naturally rises into the flow above. Meanwhile, cooler water flows downwards into the collector, thus causing circulation throughout the system. These systems are reliable. Check Valve and vent pressure relieve must be installed to ensure proper installation
