Evacuated Tube Colored Steel Non-Pressure Solar

1.Evacuated Tube Colored Steel Non-Pressure Solar provide heat water by a copper coil inside water tank.
2.Non-Pressure Solar.

Evacuated Tube Colored Steel Non-Pressure Solar, Non-Pressure Solar, Evacuated Tube, solar water heater

1.Evacuated Tube Colored Steel Non-Pressure Solar is a kind of solar water heating systems that the bellow collector directly connect with the above water tank.

2.This Non-Pressure Solar solar water heaters do not need to run the pump to force and do not require pipeline connections between the collector and the tank.

3.Non-Pressure Solar is a simple and secure way to collect solar energy.

4.Non-Pressure Solar working principle of solar water heater is make it natural circulation between the water tank and the collector pipe.

5.After the water in vacuum tube heated, natural convect into the water tank, meanwhile cold water in the tank flows down to the vacuum tubes, that is natural to run continuously to heat the water tank.
