Abstract

Die Erfindung betrifft ein Verfahren zur Erkennung eines defekten Membranausdehnungsgefäßes (1) in einem Heizkreis (2) mit einem Brenner (3), der geregelt ein- und ausgeschaltet wird, wobei der Heizkreis (2) zur Erfassung aktueller Druckdaten mit einem Drucksensor (4) versehen ist. Nach der Erfindung ist vorgesehen, dass aus den bei eingeschaltetem Brenner (3) ermittelten Druckdaten ein Druckmittelwert gebildet und dieser mit einem Druckreferenzwert verglichen wird.
