    Electrodes

    Boiler electrodes are essential components for the safe and efficient operation of your heating system. They play a critical role in the ignition and flame detection processes of your boiler. Over time, electrodes can become worn, corroded, or damaged, causing ignition problems and reducing boiler performance. Ensuring your boiler electrodes are in good condition helps maintain reliable heating and hot water. Our range includes products from major brands such as Baxi, Worcester, Vaillant, Ideal, and Glowworm.

    Signs Your Boiler Electrodes Need Replacing

    • Intermittent or Failed Ignition – The boiler struggles to light or doesn’t ignite at all.
    • Boiler Lockouts – The boiler shuts down as a safety precaution due to flame detection issues.
    • Soot or Corrosion – Build-up of soot, debris, or visible damage on the electrodes.
    • Error Codes – Many modern boilers display error codes related to ignition or flame detection failures.

    Ensure Safe and Efficient Boiler Operation

    Don’t let worn-out electrodes leave you without heating or hot water. Explore our range of high-quality boiler electrodes and keep your heating system running smoothly.

    Boiler Electrodes – FAQs

    What is a boiler electrode?

    A boiler electrode is a critical component that helps in the ignition and flame-sensing processes. Ignition electrodes create the spark needed to ignite the gas, while flame-sensing (ionisation) electrodes detect the flame to ensure the boiler operates safely.

    How do I know if my boiler electrode is faulty?

    Common signs of a faulty electrode include:

    • The boiler fails to ignite.
    • Intermittent ignition problems.
    • The boiler frequently goes into lockout mode.
    • Error codes related to ignition or flame failure.
    • Soot or corrosion build-up on the electrode.

    Can a faulty electrode cause a boiler to lock out?

    Yes, if the electrode fails to ignite the boiler or detect the flame, the boiler may enter lockout mode as a safety precaution.

    How often should boiler electrodes be replaced?

    Boiler electrodes typically last between 3 and 5 years, depending on usage and maintenance. Regular servicing helps identify worn-out electrodes before they fail completely.

    Can I replace a boiler electrode myself?

    Replacing a boiler electrode can be complicated and should only be performed by a Gas Safe registered engineer. Incorrect replacement can lead to ignition failure or safety risks.
