Abstract (en)

[origin: EP0252252A2] Gas water heater with a burner (1) and a control valve (12, 13), which controls the gas throughput to this burner (1) in proportional dependence on the respective water throughput to a heat exchanger (6), can be actuated by means of the final control element of a water switch (10) and is arranged in a gas feed line (5), as well as with an arbitrarily adjustable throttling of this gas throughput to a selectable part-output of the burner (1), the gas throughput fed to the burner (1) for starting it being set independently of this throttling, to at least a throughput adequate for firing of the burner. <IMAGE>
