Step 1: Turn Off the Heating System


The first and most crucial step is to turn off your heating system immediately. Shut down the boiler and any associated power switches or controls. Let the system cool down for a while before proceeding.


Step 2: Identify the Pressure Gauge Reading


Check the pressure gauge on your boiler to identify the current pressure reading. The ideal pressure range is typically between 1 and 1.5 bar, but this may vary depending on your boiler's make and model.


Step 3: Bleed Radiators (If Needed)


If the boiler pressure is only slightly higher than the recommended range, you can try bleeding the radiators to release any excess air, which may reduce the pressure. Use a radiator key to open the bleed valve on each radiator, allowing any trapped air to escape.


Step 4: Locate the Filling Loop


The filling loop is a connection between the mains water supply and the boiler, allowing you to top up the system's water pressure. Locate the filling loop and ensure that both ends are securely attached.


Step 5: Release Excess Pressure


If the boiler pressure is significantly higher than the recommended range, you may need to release some water to reduce the pressure. Consult your boiler's manual for specific instructions on how to release excess pressure safely.


Step 6: Recheck the Pressure Gauge


After releasing excess pressure, recheck the pressure gauge reading to ensure it falls within the recommended range. If the pressure is still too high, repeat the process until it reaches the correct level.


Step 7: Close the Filling Loop


Once the boiler pressure is back within the recommended range, close the filling loop securely to prevent overfilling.


Step 8: Restart the Heating System


With the boiler pressure normalized, you can now restart your heating system. Turn on the boiler and any associated power switches or controls.


Step 9: Monitor the Boiler Pressure


After restarting the heating system, monitor the boiler pressure over the next few hours or days to ensure it remains stable within the recommended range.
