Model Number: SD-G2 Key Specifications/Special Features: Manufacturer of solar water heaterAccepts OEMWe have CE, solar keymark, ISO9001, ISO14001Working principle: warm water rises when the phenomenon known as natural convection happens and water circulates between the collectors and thankTank must be installed above the collectorAs water in the collector is heated, it becomes lighter and naturally rises into the tank aboveMeanwhile, cooler water in the tank flows downwards into the collector, thus causes circulation throughout the system

These systems are reliable and relatively inexpensive
