Solar keymark approved pre-heated copper coil solar water heater

It is suitable for people who wants good quality hot water.


Working principle

1.The vacuum tube collector absorbs solar energy to heat the water in water tank( the water in water tank is just for heat storage and providing heat to the cold water in copper coil).


2.When using hot water, cold water flows into copper coil and exchanges heat with the hot water in water tank, so that its temperature rises up fast.


3.As the special feature of copper coil, the water temperature in the outlet pipe is always closed to the water in inner tank (difference within 3 degree centigrade).




1.High heat efficiency

2.The system works under the pressure of pipe water(Copper coil helps to endure the pressure of tap water)

3.Water quality is good(water we use is in the copper coil pipe,it is a loop run)

4.Completely automatic operation

5.Instant heat exchange and plentiful warm water 

6.Water temperature is stable 

7.Easy installation, easy operation, fashionable
