<p>The water heater has a gas burner, and an electromagnetic gas valve (8,9) controlled depending on the quantity of discharged water. A spring is held in the close position, and a control device and a water turbine (5) are integrated in a water pipe (1) for generating electrical voltage for components by the flow of water (2) by opening a hot water-discharge-valve. The water turbine is connected mechanically with a permanent magnet (7), which rotates depending on flow of water and the indicator of the gas valve stays in working connection with the circular path of the permanent magnetic pole.</p> |
