Stainless-Steel-Natural-Circulation-Solar-Water-Heater


The solar hot water heater adopts solar vacuum tube technology, the solar evacuated tubes absorber will collect heat from the sunlight and transfer into water inside the tubes. The tube water is heated to rise up and tank cold water sink down to creat a circulation, called thermosiphon effect. The water tank will be gradully full of hot water as the tubes keep collecting heat from the sunlight.  It is no need of electricity heating. It is only by solar thermal heating.
