How it is work?
It is the simplest one, the tube and tank are linked together, the working principle is like this: The vacuum tubes collect the sunshine and make the water in the tube to be hot, and then the cold water in tank will circulate with water in tank automatically from time to time. This is the simplest and cheapest model, but very efficient. In summer, the water temperature can reach up to 95 degree, nearly boiling.
