   2017 New Type Heat Pipe Pressurized Solar Water Heaters


 1.How Pressurized Solar Water Heaters works 


step 1: The absorber coating on the inner glass tube absorbs sunlight and converts it into heat. 


step 2: Steam forms inside heat pipe which transfers heat rapidly up to the manifold. and the heat transfer to the water within the tank .


step 3: When steam is cooled down,falling to the bottom of heat pipe.By continuously circulating , the tank is heated up .






 3.Key features of Solar Water Heaters:

  • No water directly flowing in the tubes, enabling the system still workable in case of occasional tube breakage.
  • Completely automatic operation with intelligent controller.
  • Antifreezing, all-year-round service even in extremely cold area.
  • Adopting the best conduction performance metal- copper TU1(heat pipe).
  • Directly connected with city water without a circulation pump
  • Withstanding high pressure (0.6MPa), comfortable shower.
