Abstract (en)
[origin: EP0389782A2] In devices of the generic type, the gas supply to the burner of the device is only opened when the heat requirement predetermined by the drawing quantity or the deviation from setpoint of the regulated water temperature corresponds at least to the excess ignition gas quantity, in order to prevent a gradual opening of the valves. The known devices of the generic type are to be simplified with the current invention. To achieve this aim, a pneumatic snap valve (32, 52, 62) is provided in addition to a main valve (30, 50, 60), which can be combined with the latter in a space-saving and equipment-saving manner. Preferred area of application is gas-heated water heaters with constantly regulated outlet temperature. <IMAGE>
