Abstract

Die Erfindung betrifft einen gasbeheizten Wassererhitzer, mit einem als Lamellenblock mit durchgeführten Wasserrohren ausgebildeten Wärmeübertrager und einer einen Schacht für die Verbrennungsgase umschließenden Brennkammer, zu deren Kühlung wasserführende Kanäle an bzw. in mindestens einer Brennkammerwand vorgesehen sind.The invention relates to a gas-heated water heater, with a as a finned block with water pipes trained heat exchanger and a shaft for the combustion chamber enclosing the combustion gases, to the Cooling water-carrying channels on or in at least one Combustion chamber wall are provided.

Es wird vorgeschlagen, daß die Vorderwand (18) der gekühlten Brennkammer (10) und der Wärmeübertrager (20) als getrennte Baugruppen ausgeführt sind. Es wird weiterhin vorgeschlagen, daß die wassergekühlte Ausführung einer Vorderwand (18) von den anderen Brennkammerwänden (12, 14, 16) durch Mittel (70, 72 bzw. 78, 80) abnehmbar bzw. abschwenkbar ist, ohne den an ihr anschließbaren Heizkreislauf unterbrechen zu müssen. Dadurch ist insgesamt erreicht, daß die Brennkammer einfacher hergestellt werden kann, als ein umfangsgeschlossener Schacht und daß auch die Montage des Wärmeübertragers an der Brennkammer, sowie die Wartung von Wärmeübertrager und Brennkammer wesentlich erleichtert sind.

Figure 00000001
It is proposed that the front wall (18) of the cooled combustion chamber (10) and the heat exchanger (20) are designed as separate assemblies. It is further proposed that the water-cooled design of a front wall (18) can be removed or swiveled away from the other combustion chamber walls (12, 14, 16) by means (70, 72 or 78, 80) without interrupting the heating circuit that can be connected to it to have to. The overall result of this is that the combustion chamber can be manufactured more easily than a circumferentially closed shaft and that the assembly of the heat exchanger on the combustion chamber and the maintenance of the heat exchanger and combustion chamber are also considerably easier.
