    Follow these steps to effectively refill your boiler and restore water pressure.

    1. Check the Pressure Gauge
      Locate the pressure gauge on your boiler. If the reading is below 1 bar, it indicates low water pressure.

    2. Locate the Filling Loop
      Find the filling loop, usually a flexible hose connecting the cold water supply to the boiler.

    3. Open the Filling Valve
      Using the adjustable wrench, gently open the filling valve. Monitor the pressure gauge as you do this.

    4. Refill the System
      Allow water to flow into the system until the pressure reaches between 1 and 1.5 bars. Close the filling valve securely.

    5. Bleed Radiators
      If air is trapped, bleed the radiators by using a radiator key. This step releases any trapped air and helps maintain optimal pressure.

    6. Check for Leaks
      Inspect the system for any visible leaks. If leaks are present, repair them before proceeding.

    7. Restart the Boiler
      Turn the power back on and allow the boiler to operate. Monitor the pressure gauge to ensure it remains stable.
