Abstract

Die Erfindung geht auf von einem Verfahren und einer Vorrichtung zum Betreiben eines Heizgeräts mit einer Abgasabführung, einem Regler für eine Solltemperatur und einem Brenner, der innerhalb eines vorgegebenen Leistungsbereichs wärmebedarfsabhängig modulierend steuerbar ist. Es wird vorgeschlagen, daß der Regler den Brenner (10) im modulierenden Leistungsbereich getaktet unterbricht und das Taktverhältnis (v) von Einschaltphase zur Ausschaltphase auf die für die Feuchtigkeitsempfindlichkeit der Abgasabführung maßgebenden Parameter, (Länge, Querschnittsform und -größe, Wärmeleiteigenschaften insbes. eines Schornsteins) abgestimmt ist. Dadurch kann eine Durchfeuchtung des Schornsteins ohne merkliche Beeinträchtigung des Gerätewirkungsgrades und der Regelgüte verhindert werden.

The invention relates to a method and a device for operating a heater with an exhaust gas discharge, a controller for a target temperature and a burner, which can be controlled in a modulating manner within a predetermined power range depending on the heat demand. It is proposed that the controller intermittently interrupt the burner (10) in the modulating power range and the pulse ratio (v) from the switch-on phase to the switch-off phase to the parameters relevant to the sensitivity to moisture of the exhaust gas discharge, (length, cross-sectional shape and size, thermal conductivity properties, in particular of a chimney ) is coordinated. This prevents the chimney from being dampened without noticeably affecting the efficiency of the appliance and the quality of the control.
