What it is
The Vaillant 0020177970 is an insulation component for Vaillant unvented hot water cylinders. It is designed for the auroSTOR VIH S and VIH R ranges, as well as Vantage VIH R models. Its function is to provide thermal insulation, reducing standing heat loss from the cylinder.
Signs this part needs replacing
- Visible cracks, tears or crumbling of the insulation material
- Increased heat loss from the cylinder, leading to higher energy bills
- Condensation or dampness around the cylinder
- Insulation becoming detached or loose
- Discolouration or brittleness due to age
Before you order
- Confirm your appliance model matches one listed in the Fits section
- Check the existing insulation for the part number or a visual match
- Ensure the insulation is for the correct cylinder size (1500 or 2000)
- Verify that the insulation is the correct component for your specific Vaillant cylinder
