What it is

The Worcester Bosch 87155045250 is a condensate adaptor supplied as an on-wall fixing set. It is a Worcester Bosch spare listed for use in the diverter valve section of Greenstar boilers, where the diverter valve directs hot water either into the heating circuit or the domestic hot water circuit so a combi can supply both without a storage cylinder. The adaptor and fixing set provides the connection and wall mounting point for the condensate route on the appliance.

Signs this part needs replacing

  • Condensate leaking or dripping at the wall entry point below the boiler
  • Damp patches, staining or water tracking on the wall around the fixing position
  • Cracking, distortion or corrosion visible on the adaptor body
  • The fixing set no longer holding the condensate pipework securely against the wall
  • The boiler locking out or shutting down because condensate cannot drain away correctly

Before you order

  • Check the GC number and the appliance data plate to confirm your model appears in the compatibility list.
  • Compare the existing adaptor and wall fixing arrangement with the part before ordering, as layout varies between Greenstar ranges.
  • Check whether a replacement seal or gasket is needed at the same time as the adaptor.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
