What it is
The insulation panel that fits to the front of the heat exchanger in Potterton Commercial Sirius 2 gas boilers. It is supplied under part number 5141553 and is listed by the manufacturer for the WH90 and WH110 models within that range. Its function is to retain heat at the exchanger face and limit radiated loss into the boiler casing.
Signs this part needs replacing
- The insulation is cracked, crumbling or breaking away from the heat exchanger face
- Blackened, scorched or heavily discoloured insulation material
- Sections of insulation missing, leaving the exchanger surface exposed
- Heat damage or distortion visible on the panel during a service inspection
Before you order
- Confirm the boiler model is a Potterton Commercial Sirius 2 WH90 or WH110
- Check the part number 5141553 against the number on the existing insulation or the manufacturer's parts listing
- Confirm whether the insulation requiring replacement is the front panel, as other insulation components are separate parts
- Inspect the heat exchanger face for any further damage before fitting
