Copper coil solar water heater Pre-heating solar water heater

 

Feature:

1. the cooper coil inside of the non-pressure tank can bear the pressure 0.7 Mpa during the operation.

2. there is feeder tank which can load the water automatically.

3. the vacuum tube heat the water and supply hot water to the tank, then the water in the copper coil can be heated by the hot water in the water tank.

4. it is pre-heating and heat exchange process.

5. only if the water in the tank is hot, more hot water will be got and exceed the capacity limit of the water tank.

6. clean hot water from the copper coil.

7. you can use the hot water inside of the copper coil or the hot water in the tank.
