    O'Rings & Seals, Washers & Gaskets

    Boiler seals are essential components that help maintain the safety, efficiency, and proper function of your heating system. These seals create a secure barrier between different parts of the boiler, preventing leaks of water, gas, or combustion by-products. Over time, seals can degrade, harden, or crack, making regular inspection and timely replacement critical to avoid costly repairs or safety risks.

    Boiler Seal – FAQs

    What is a boiler seal?

    A boiler seal is a gasket or sealing component used to prevent leaks of water, gas, or combustion fumes in a boiler. These seals help ensure the boiler operates safely and efficiently by maintaining a secure and airtight barrier between different parts.

    How often should boiler seals be replaced?

    Boiler seals usually last between 5 and 10 years, depending on the boiler’s usage and maintenance. During annual servicing, an engineer can check the condition of the seals and replace them if necessary.

    What happens if I don’t replace a faulty boiler seal?

    Failing to replace a faulty boiler seal can lead to:

    • Water Leaks: Causing damage to the boiler or surrounding areas.
    • Gas Leaks: Increasing the risk of dangerous carbon monoxide exposure.
    • Pressure Loss: Reducing the efficiency of the heating system.
    • Boiler Damage: Prolonged leaks can damage internal components, leading to costly repairs.

    Can a faulty boiler seal cause the boiler to lose pressure?

    Yes, a faulty boiler seal can cause water to leak, leading to a drop in system pressure. This can affect the efficiency and performance of your boiler.
