Abstract

Die Erfindung geht aus von einem gasbeheizten Wassererhitzer mit einer Abgasüberwachungseinrichtung, die eine Strömungssicherung (10) und einen außerhalb der Strömungssicherung (10) angeordneten Temperaturfühler (16) zur Erfassung der Abgastemperatur bei Rückstau der Abgase aufweist. Es wird vorgeschlagen, daß der Abgastemperaturfühler (16) auf der Höhe einer in einer Abgasabführung (12) angeordneten Öffnung (18) angeordnet ist. Dadurch wird einerseits eine schnelle Ansprechzeit im Sicherheitsfall gewährleistet und andererseits ist die vorgeschlagene Vorrichtung universell bei gasbeheizten Wassererhitzern unterschiedlicher Leistungsgrößen einsetzbar.

The invention relates to a gas-heated water heater with an exhaust gas monitoring device, which has a flow safety device (10) and a temperature sensor (16) arranged outside the flow safety device (10) for detecting the exhaust gas temperature when the exhaust gases are backflowed. It is proposed that the exhaust gas temperature sensor (16) be arranged at the level of an opening (18) arranged in an exhaust gas outlet (12). On the one hand, this ensures a fast response time in the event of a safety event, and on the other hand the proposed device can be used universally in gas-heated water heaters of different output sizes.
