What it is
The Vaillant 0020213911 is a burner assembly for Vaillant gas boilers. It sits at the heart of the combustion chamber, where the gas and air mixture is delivered and ignited to produce the flame that heats the appliance's water circuit. It is listed by Vaillant as the burner for the ecoTEC Pro 28, ecoTEC Sustain 24, 28 and 34, and the corresponding VUW combi models.
Signs this part needs replacing

- Soot deposits, discolouration or heat damage visible on the burner body or its ports

Before you order
