What it is

The Vaillant Insulation Below 0020085711 is the base insulation component fitted beneath the cylinder body. It sits under the appliance to reduce heat loss through the base and to protect the surface the cylinder stands on. It is listed by Vaillant for use with the Allstor VPS 1500/2 unvented hot water cylinder.

Signs this part needs replacing

  • Visible dampness, staining or water marking on the insulation or the floor beneath the cylinder
  • Insulation that has compressed, crumbled or broken up, leaving the cylinder base exposed
  • Condensation forming under the cylinder or on the surface it stands on
  • Increased heat loss from the base of the cylinder, with the surrounding area feeling warm
  • Physical damage to the pad caused during servicing or cylinder removal

Before you order

  • Confirm the cylinder model on the appliance data plate matches the Allstor VPS 1500/2
  • Check that the failed component is the base insulation and not the cylinder shell insulation
  • Inspect the base of the cylinder for any underlying leak before fitting new insulation
  • Have the manufacturer part number 0020085711 to hand when ordering
