Sunlight passes through the first layer of glass of the heat-absorbing tube onto the black heat absorption layer of the second layer of glass, absorbing the heat of the sun's light energy, and because the two layers of glass are vacuum insulated, the heat transfer will be greatly reduced So that the water in the glass tube heating, heated water will be lightly along the glass tube heating surface into the insulation storage bucket, the barrel of the relatively low temperature of water along the surface of the glass tube into the glass tube supplement, so constantly circulating, so that the insulation storage bucket in the water heating, so as to achieve the purpose of hot water.
