What it is
The Buderus 73543 insulation casing is a thermal insulation component that fits around the isolation valve assembly on Buderus 600 series gas boilers. Its purpose is to limit heat loss from the valve body and shield adjacent components from radiated heat. It is supplied under Buderus part number 73543.
Signs this part needs replacing
- Cracking, crumbling or breakdown of the casing material
- Heat damage, scorching or discolouration around the isolation valve
- Casing loose, displaced or no longer seated correctly on the valve body
- Damp or stained insulation indicating a weep at the isolation valve
- Casing damaged or broken up during servicing of the valve assembly
Before you order
- Confirm the boiler model against the fitment list above
- Check that the existing casing or valve assembly is marked with part number 73543
- Inspect the isolation valve itself for leaks or seizure, as the casing alone will not correct these faults
