Abstract

Die Erfindung betrifft ein Verfahren zum Entlüften einer Kreiselpumpe, insbesondere im Wasserkreislauf einer Heizungsanlage oder eines Warmwasser erzeugenden Boilers, wobei die Pumpe vorzugsweise direkt im oder am Ein- oder Auslass eines Heizkörpers angeordnet ist. Zum Befreien des Laufrades und/oder des das Laufrad umgebenden Raumes von Luft, wird die Pumpendrehzahl von der Normaldrehzahl insbesondere kurzzeitig auf eine solch niedrige Drehzahl heruntergesteuert, dass sich die Luft vom Laufrad trennt und aus dem Laufradraum austritt.
