What it is

This is the rear insulation for the heat exchanger, manufactured by Ferroli and identified by part number 39811780. It sits behind the heat exchanger on Econcept boilers, where it limits heat loss to the surrounding casing and internal components. The insulation is a serviceable item and is replaced when it becomes damaged, compressed or contaminated.

Signs this part needs replacing

  • The insulation is crumbling, flaking or breaking up on contact
  • Visible scorching, charring or deformation of the insulation material
  • The insulation has become damp, saturated or contaminated with debris
  • Heat is escaping around the heat exchanger area, with unusually high casing or component temperatures
  • The insulation has been disturbed or compressed during previous work and no longer sits correctly

Before you order

  • Confirm your boiler model against the fit list above, including any commercial variant
  • Check the existing part number against the manufacturer's parts list for your appliance
  • Verify that the rear insulation is the section required, as front and rear insulation are separate items
  • Have the appliance model and serial details to hand when checking compatibility
