Vaillant is a German manufacturer, founded in 1874. They designed their first boiler in 1894 and the world’s first wall-hung gas boiler in 1905, so they’re an established industry leader. Their first combi-boiler went on sale in 1967. Many older Vaillant boilers are still in use because of their long-term reliability. We stock the full range of Vaillant boiler spares; everything from the smallest sealing ring up to full heat exchanger units. Buying original and brand new components guarantees that you’ll get maximum performance and reliability from the boiler for years to come. Using outdated or salvaged parts is not recommended. Not only are these parts often impaired through use and handling, but in many cases, they have been superseded by improved components. Parts that have been recently upgraded include the pumps and PRVs, pressure sensors and the combustion seals inside certain models of the heat exchanger. If you don’t see the exact Vaillant boiler parts number that you are replacing, there will still be suitable Vaillant spares in our catalogue. For example, original Vaillant Ecotec Plus 831 parts can sometimes be substituted with similar parts in the Vaillant range. So if your existing Vaillant boiler parts carry a slightly different part number this is unlikely to be a problem. Simply call our customer service line and our experts will confirm the part you need. Our gas heating and plumbing spares are available for next business day delivery throughout most of the UK.
