Solar collector evacuated tubes collect and convert sunshine energy into thermal en-ergy, which is transferred to the central heat pipes in the tubes through the aluminum fins bridging the tube inner surfaces and the heat pipes. The copper heat pipes have tiny amount of purified water sealed in them at depressurized condition. When heated, the water inside the heat pipes vaporizes at low temperature (about 30 ). The vapor (steam) rises to the pipe tips inserted into the water contained in the tank. Vapor is cooled down and becomes condensate falling to the bottom of the pipes. By continuously circulating this way, heat is carried from outside to the water inside the tank.
Even in the winter or the cloudy days, you can still use this products. We can use the heat element as a auxiliary energy to heat the water. The main source is still the solar energy. We can use the computer controller(model TK7-Y) to control the heatelement to work automaticly.
If you have any especial requirement,please tell us ,we will make it according to your requirement.

 Advantage Of Porcelain Enamel Tank
 No contacting point, no leakage, long life, It is manufactured by choosing special qualified porcelain enamel steel plate and integrated stretching one time molding process and no wire automatic plasma welding. Meanwhile being introduced recent technology from Germany, it melts special silicon compound after baking at 900*Cdegree and inner flask steel wall and forms special Blue -Gold Titanium Steel inner vessel. It features no corrosion forever, no leakage forever, no scale forever, no shrunken by pumping, no broken by pressing, etc. It is unique special inner flask in China .Particularly it is suitable for salina, seawater, deep well at different region. Its operation life will be over 15 years.
