What it is

The Worcester Bosch 87186821650 is a left-hand tank insulation panel (heatshield) for the Greenstar Highflow range of floor-standing combination boilers. It wraps the left side of the internal hot water storage tank to reduce standing heat loss. The panel is shaped to the tank profile and is supplied as a single left-hand section.

Signs this part needs replacing

  • Visible tearing, crumbling or delamination of the insulation panel
  • Bare or exposed tank surface where the panel has slipped or fallen away
  • Increased standing heat loss from the appliance casing
  • Condensation or damp patches around the tank area
  • Panel distorted or scorched after work inside the appliance

Before you order

  • Confirm the appliance model and GC number against the data badge
  • Check whether the left-hand or right-hand panel is required
  • Inspect the existing panel for damage before removal to confirm the correct section
  • Verify the part number 87186821650 matches the number on the existing component
