    Pressure Gauges

    At National Boiler Spares, whether you’re replacing a worn valve or upgrading your system, our range of high-quality pressure valves ensures safety and reliability.

    Boiler pressure valves are crucial components in any heating system, ensuring safe operation by regulating and relieving excess pressure. These valves work in conjunction with other system parts to prevent over-pressurisation, protect the boiler from damage, and maintain efficient performance.

    Worn or malfunctioning pressure valves can lead to dangerous and costly issues in your heating system. Common signs that a pressure valve may need replacement include: 

    • Pressure relief valve leaking
    • Frequent pressure drops or surges
    • Boiler frequently shutting down
    • Inconsistent system pressure 

    Replacing faulty pressure valves promptly is vital to ensure the safety, efficiency, and longevity of your boiler system.

    Boiler pressure gauge – FAQs:

    What is a pressure gauge in a boiler, and what does it do?

    A pressure gauge measures and displays the internal pressure of the boiler system. It provides real-time information to ensure the system operates within safe limits, preventing over-pressurisation and potential equipment failure. It also helps diagnose issues by revealing fluctuations or irregularities in pressure.

    Where is the pressure gauge located on a boiler?

    The pressure gauge is typically located on the front or side of the boiler near the control panel, making it easy to monitor.

    What is the normal pressure range for a boiler?

    For most residential hot water boilers, the normal pressure range is between 12 and 15 psi when the system is cold, and it can rise to 20 to 25 psi when the system is running. Steam boilers typically operate between 0.5 to 2 psi.

    What causes pressure gauge failure?

    Pressure gauges can fail due to: 

    • Corrosion or buildup inside the gauge.
    • Mechanical wear over time.
    • Blockages in the connection line.
    • Vibration or impact damage.

    What happens if my boiler pressure is too high?

    If boiler pressure exceeds safe levels, it can cause the pressure relief valve to open, preventing damage. Prolonged high pressure can damage components and lead to leaks or failures.Â
