Work principle
The vacuum tubes absorb the sunshine heat energy, heat the water inside the tube. hot water rising up to the tank, cold water inside the tank lower to the tube. The nature circulation movement make the water warmer and warmer. The maximum temperature can be 100℃. Due to the system is non pressure, so the tank need an open vent.
