Vacuum Tube Solar Water Heater Thermosiphon System
200L Compact Non Pressurized Vacuum Tube Solar Water Heater Thermosiphon System
Working principle:
Larger proportion of hot water than cold water, cold water flows downward and hot water goes upward.
Water will be heated continuously between water tank and vacuum tube.
Hot water always floats on cold water.
Hot water flows to water tank from vacuum tubes.
Proportion cold water flows to vacuum tubes from water tank .
Certificate:CE
