What it is

The Ideal 178940 jacket assembly is the outer casing set for the Instinct Heat range of commercial boilers. It forms the protective enclosure around the heat exchanger and internal components, holding the appliance insulation in place and shielding the working parts from dust and accidental contact. Ideal supplies it as a direct replacement for the original panel set on these appliances.

Signs this part needs replacing

  • Cracked, dented or split casing panels
  • Missing or detached jacket sections leaving internal components exposed
  • Corrosion or rust staining across the panels
  • Loose or broken fixings that stop the jacket seating correctly
  • Insulation or lining that has degraded or come away from the panel

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering.
  • Compare part number 178940 with the number on the existing jacket or in the appliance manual.
  • Check the casing fixings and any seals for reuse; replace anything that is damaged or missing.
  • Isolate the appliance and let it cool before removing or refitting the casing.
