High Boiler Pressure

With a typical ‘wet heating system’ your boiler heats up water to warm your radiators and requires a minimum pressure to pump the water around your system, ideally between 1 to 2 bar. However, it’s normal for your pressure to rise up to 2.5 bar when both your heating and hot water is being used.

To lower the pressure and stay within the recommended range the simplest step is to bleed one of your radiators to remove excess water. If you find that your boiler pressure continues to increase, check that the filling valve under your boiler is closed. If in doubt, contact a Gas Safe heating engineer.

Low Boiler Pressure

Boilers require a minimum amount of pressure to work. If the water pressure drops below 1 bar there are steps you can take to repressurise your boiler by adding water to the system using its filling loop:

Check your boiler’s manual before you begin

Turn your boiler off and allow everything to cool down

Find the filling loop

Make sure you can see your boiler pressure gauge before attempting to re-pressurise

Open the first valve fully

Open the second valve slowly to start adding water to your system

Once the pressure reaches 1.5 bar close both valves and lock

Turn your boiler back on. You may need to press the reset button
