Working Principle
Thermosiphon Solar Water Heater works in this way: warm water rises when the phenomenon known as natural convection happens and water circulates between the collectors and tank. The tank must be installed above the collector. As water in the collector is heated, it becomes lighter and naturally rises into the tank above. Meanwhile, cooler water in the tank flows downwards into the collector, thus causes circulation throughout the system. These systems are reliable and relatively inexpensive.
Key features:
1 Can be operated completely automatic if connect with intelligent controller;
2 Simple structure,easy plug-in installation.Can be installed both on flat and inclined roof,and can be used with an auxiliary electric booster as to provide hot water without sunshine or the water temperature is below the desired level;
3 All-glass vacuum tube is of high-temperature resistance,cold resistance,and high-efficient absorbability.High efficiency with daily average efficiency higher than 50%;
4 Superior heat preservation ensured by one-off molding polyurethane foam with thickness 50-65mm,the heat preservation performance is endurable and steady;
5 The frame is designed with an overall industrial model,which is simple,direct and stable,well wind resistance;
6 Very little maintenance and very low operating cost.
