What it is

The Ideal 173520 is a combustion chamber insulation kit manufactured for Ideal boilers. It is fitted inside the combustion chamber, where it limits the amount of heat escaping through the chamber side panels. Keeping that heat within the chamber supports boiler efficiency and reduces the risk of heat damage to surrounding internal components.

Signs this part needs replacing

  • Insulation boards that are cracked, crumbling or breaking away from the chamber walls
  • Discolouration, scorching or blackening of the insulation surface
  • Soot or debris build-up on the insulation that cannot be cleaned back
  • Heat escaping past the chamber side panels, with unusually high casing or flue temperatures
  • Overheating or heat-related damage to components sitting close to the chamber

Before you order

  • Check the GC number on the appliance data badge against the compatibility list before ordering.
  • Confirm the boiler model matches one of the 36 listed appliances, as the same part number can appear across several ranges.
  • Inspect the chamber seals and gaskets while the chamber is open and renew them if they are showing signs of wear.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
