What it is

The Alpha combustion chamber insulation panel set, part number 3.016448, is a shaped insulation kit that lines the combustion chamber of Alpha HE and He range gas boilers. It shields the surrounding casing and internal components from combustion heat and helps maintain stable chamber temperatures. The set is fitted in the burner area of the appliance.

Signs this part needs replacing

  • Visible cracking, crumbling or flaking of the insulation surface
  • Discolouration, charring or blackening beyond normal heat marking
  • Insulation material breaking away and falling into the combustion chamber
  • Damp or contaminated panels following a leak or condensate ingress
  • Heat damage to the boiler casing or surrounding components

Before you order

  • Confirm your boiler model matches one of the LPG variants listed above
  • Check the existing panel's part number against 3.016448
  • Inspect the full combustion chamber insulation, not just the visible face
  • Confirm the appliance is the LPG version, as listed
