What it is

This is the lower insulation for the boiler body, supplied by Potterton under part number 5139888. It is the insulating panel fitted to the lower section of the boiler body on Potterton Commercial appliances, where it reduces heat loss from the casing and protects surrounding components from radiated heat.

Signs this part needs replacing

  • Insulation panel is damp, soft or has broken down in service
  • Visible crumbling, flaking or disintegration of the insulation material
  • Panel no longer sits correctly against the boiler body
  • Casing around the lower body feels unusually hot in service
  • Heat marks or discolouration on adjacent components

Before you order

  • Confirm the boiler model and section count against the fit list
  • Check the existing insulation position on the boiler body to confirm it is the lower panel required
  • Note the part number 5139888 to match against the appliance documentation
  • Do not estimate dimensions; ordering is by part number and section count only
