Understanding the common issues that lead to this problem is essential for effective troubleshooting. This section provides a clear, step-by-step guide to help you identify the fault and restore hot water quickly.

    Follow these steps to diagnose and fix the problem of your boiler not heating water.

    1. Check the Thermostat Settings
      Ensure the thermostat is set to the desired temperature. If it is too low, increase it and monitor if the boiler responds.

    2. Inspect the Power Supply
      Verify that the boiler is receiving power. Check circuit breakers and fuses for any issues.

    3. Flush the Boiler
      If sediment buildup is suspected, perform a flush.

    4. Turn off the power and water supply.

    5. Attach a hose to the drain valve and direct it to a suitable drainage area.

      If air is trapped in the system, bleeding the radiators can help.

    9. Use a radiator key to open the bleed valve at the top of each radiator.

    10. Allow air to escape until water begins to flow, then close the valve.

    11. Examine the Pressure Relief Valve
      If the boiler cycles frequently, inspect the pressure relief valve.

    12. Look for leaks or signs of wear.

    13. Replace the valve if necessary.
