| Abstract: | A novel erevacuated bottle solar water heater is introduced, where the heat loss is decreased and absorbance is increased owing to a vacuum gap between the inner glass liner and the outer one and black porous absorbing medium respectively. Theoretical calculation and experimental study show that the heater is characterized by its higher thermal efficiency, simple structure and easy processing and low cost. |

| Keywords: | Evacuated bottle porous medium cubic absorption spherical part columnar part |
