Jaguar branded boilers were produced for Plumb Center UK and the Wolseley group, mainly by Glow-worm, which has since been absorbed by Vaillant. Although it is unclear whether Vaillant or Plumb Center will revive the Jaguar brand name, some components are equivalent and interchangeable with those in Glow-worm boilers; however, others are not. The majority of our Jaguar spares are original Jaguar components, although some may be branded Glow-worm or Icon. Our Jaguar boiler spares include heat exchangers, water cocks, pressure switches, fan assemblies, pressure vessels, thermistors and flow sensor microswitches. If there are any Jaguar boiler spares you need but do not see listed, just call us and will do our best to supply it. Jaguar boilers are neither the best nor worst boilers on the market, but they are relatively easy to service and repair. Most Jaguar boiler spares are suitable for a range of different Jaguar boiler models; for example, a Jaguar boiler diverter valve will fit all 23kW, 24kW and 28kW combi boiler models. For other parts, including the heat exchanger, it is important to check the model number carefully. If you are in any doubt, just call us for advice. Most replacement components will also come complete with accessories such as O-rings and gaskets. The Jaguar boiler diverter valve, for example, uses two O-rings and five gasket washers, so this is a great advantage to the fitter and saves wasted call-outs or mistakes.
