What it is

The heat exchanger baffle, manufacturer part number 120012, is a Halstead component used in the HERO and Wickes HEAT range of gas boilers. It sits within the heat exchanger to direct the flow of combustion gases across the exchanger surfaces. Correct baffle fitment supports efficient heat transfer and stable flue gas temperatures.

Signs this part needs replacing

  • Combustion readings drifting outside the expected range for the appliance
  • Visible distortion, corrosion or burn-through on the baffle surface
  • Baffle loose, displaced or no longer seated correctly in the heat exchanger
  • Overheating or poor heat transfer performance traced to the exchanger
  • Debris or soot build-up on a damaged or degraded baffle

Before you order

  • Confirm the boiler model and GC number against the fitment list above
  • Check the existing baffle for damage and confirm the part number 120012 is required
  • Verify the quantity needed, as some heat exchangers use more than one baffle
  • Isolate the appliance and follow the manufacturer's instructions before fitting
