What it is
The Vaillant 0020177966 is a sacrificial anode for Vaillant unvented hot water cylinders. It sits inside the cylinder and corrodes in preference to the steel shell, protecting the vessel from corrosion over its service life.
Signs this part needs replacing
- Rumbling, knocking or popping noises from the cylinder while it heats
- Discoloured or metallic-tasting hot water
- Unpleasant odour from the hot water supply
- Visible corrosion, pitting or heavy depletion on the anode when inspected
- Anode core exposed with little sacrificial material left
Before you order
- Confirm your cylinder model and year against the fitment list above
- Check the part number on the existing anode or against the manufacturer's parts list
- Confirm how many anodes your cylinder requires
