Abstract
A water heater includes a water pipe form by bending a pipe. The entire water pipe leans related to a vertical plane to expose all the section to a burner thereunder. All the sections of the water pipe lean downwards related to a horizontal plane. It will make the water in the water in the water pipe flows backwards when no water is supplied to the water heater. Therefore, there will never be water remaining in the water pipe to get rid of the jam problem.
