What it is

The Viessmann 7824218 is a sealing kit supplied for Vitodens WB1A heating only boilers built from 27.04.2005. It provides the seals required at the joints and connections it is specified for within the appliance, preventing water or gas loss at those points. The kit is listed under O-rings, washers and gaskets in the Viessmann boiler spares range.

Signs this part needs replacing

  • Visible weeping or damp staining around the joint the seal serves
  • Water tracking or drips at the boiler connections during operation or after shutdown
  • Seals that have hardened, flattened, cracked or lost their profile
  • Scale, corrosion or debris build-up on the sealing faces
  • Repeated pressure loss that traces back to a sealed joint

Before you order

  • Confirm your appliance is a Vitodens WB1A heating only 18kW or 24kW model
  • Check the serial number against the listed units where applicable
  • Verify the appliance was manufactured on or after 27.04.2005
