What it is
The Trianco SP221865 is a back casing assembly for Trianco electric boilers. It forms the rear section of the appliance casing on the Aztec and INCA 2KW models, enclosing the rear of the boiler body. It is supplied as a single assembly.
Signs this part needs replacing
- Visible corrosion, cracking or deformation of the rear casing panel
- Impact damage from installation or servicing work
- Casing no longer seats correctly against the appliance body or fixings will not tighten
- Water staining or corrosion behind the casing indicating prolonged moisture exposure
Before you order
- Confirm the boiler model matches one of the listed fits, as casing panels differ between output ratings
- Check the existing casing for a part number marking to confirm SP221865 or 221865
- Inspect the appliance for any further casing or sealing components required at the same time
