 There are some similars with unpressurized solar water heater, but we usually use the water in the copper coil. The water in the water tank to be heated then it will conduct the heat to the copper coil in the tank, heating the water in the copper coil.


1. It fits with international market, adopting copper coil as heat exchange.

2. Take advantage of tap water's pressure.

3. It can provide hot water with constant temprature, it is safe and more comfortable

4.High quality hot water to be supplied.

5. It can produce more hot water than general types because it isn't restricted by the capacity of tank

6. Can be used single or many cells as solar heat system
