What it is

The Ideal 177967 diffuser is a heat exchanger component used in Ideal Commercial appliances. It sits within the heat exchanger assembly and guides the passage of combustion gases across the exchanger surfaces, helping to keep heat transfer even and combustion stable. It is supplied as a direct replacement for the original factory-fitted part.

Signs this part needs replacing

  • Overheating or unstable combustion readings on the appliance
  • Visible distortion, cracking or corrosion of the diffuser
  • Soot deposits or an uneven flame pattern across the burner
  • Repeated lockouts or fault codes linked to combustion
  • Heat exchanger surfaces showing localised hot spots

Before you order

  • Confirm the appliance model and serial number against the compatibility list
  • Check the part number stamped or marked on the existing component before ordering
  • Inspect the heat exchanger gasket or seal and replace it if it shows signs of damage
