Phase change heat-conductive & pressure resistant solar power water heater transform the solar power into heat energy by using the vacuum tubes, which has the high capability of absorbing and preserving the solar energy. The phase change heat-conductive tube inserted in the vacuum tube will conduct the heat into the water tank quickly, and the water temperature in the tank will gradually rise.

The vacuum tube has the capability of following the solar radiation. So long as there is solar radiation, the tube will work. As the phase change heat-conductive tube has the characteristics of conducting the heat in one direction, it can work effectively in the extremely cold area in all seasons.

The phase change heat-conductive tube is a kind of inorganic agent filled in metal tube and processed in vacuum state. It is a heat-conductive component that work through the phase change of the agent in the tube.
