What it is

The Insulation RH (part number 87186908570) is a right-hand insulation panel manufactured by Worcester Bosch. It is fitted within the casing of Greenstar Danesmoor External and System EXT ErP oil boilers, where it reduces heat loss from the appliance and protects surrounding components from radiated heat.

Signs this part needs replacing

  • Visible cracking, crumbling or breakdown of the insulation material
  • Water staining, dampness or softening of the panel
  • Insulation detached from its mounting or sagging out of position
  • Exposed metal surfaces where insulation coverage has been lost
  • Localised overheating or condensation around the right-hand casing area

Before you order

  • Confirm the boiler model matches one of the Greenstar Danesmoor External or System EXT ErP variants listed above
  • Check that the failed insulation is the right-hand panel, as left and right panels are separate parts
  • Compare the part number 87186908570 against the manufacturer's parts list for your appliance before ordering
  • Inspect the surrounding casing and insulation for further damage that may also require attention
