What it is

The Vaillant 0020136635 Casing Back is a replacement rear casing panel supplied with a T2H thermal fuse. It forms part of the outer enclosure of the appliance, closing off the rear of the unit and shielding the internal components from dust, moisture and accidental contact. The T2H fuse carried with the panel is a thermal protection device that interrupts the circuit if temperatures exceed a safe limit.

This is a Vaillant-manufactured spare, listed under the casings, covers and panels category, and is intended for use within Vaillant standard water heater assemblies.

Signs this part needs replacing

  • Visible cracks, splits or distortion in the rear casing panel
  • Corrosion or rust staining along the panel edges or fixing points
  • A blown or open-circuit T2H thermal fuse preventing the appliance from running
  • Loose or damaged fixings that leave the casing back unable to seat correctly
  • Signs of moisture or debris entering the appliance through a damaged rear panel

Before you order

  • Confirm the appliance model and GC number from the data badge before ordering
  • Check the existing part number on the old casing back matches 0020136635
  • Inspect any seals, gaskets or fixings around the casing for wear, as these may need replacing at the same time
