What it is

The rear insulation panel is a Worcester Bosch component (part number 87186908580) used on Greenstar Danesmoor External and System EXT ErP oil boilers. It sits at the rear of the appliance casing and limits heat transfer away from the combustion area. The panel forms part of the boiler's thermal insulation set and is replaced when the existing material has degraded.

Signs this part needs replacing

  • Visible crumbling, flaking or breakdown of the insulation material
  • The panel has become damp, soft or compressed in service
  • Discolouration or scorching on the rear casing area
  • Insulation has detached from its mounting position
  • Heat is being retained poorly, with the rear casing running noticeably warmer than usual

Before you order

  • Confirm your boiler model against the fitment list above
  • Check that the rear panel, rather than the front or side insulation, is the part required
  • Inspect the existing panel for damage before removal so the correct component is identified
  • Have the appliance isolated and cooled before any work on the casing or insulation
