working principle

 

Because of the larger proportion of hot water than cold water, cold water flows downward

and hot water goes upward. The water will be heated continuously between water tank 

and vacuum tube. In other wards, hot water always floats on cold water.The hot-water flows to the water tank from the vacuum tubes. Because of the proportion.
