The pressure gauge of the boiler is a vital component. You must check it occasionally to ensure that the boiler is operating in an optimum condition. The boiler pressure may rise with the heat every time and come down when the temperature subdues.


Boiler Servicing and Boiler Pressure


The pressure gauge on a combi-boiler or a traditional boiler can be found in the front. If it’s not on the front, you can find it behind the control panel. The low boiler pressure is marked by green colour, and the high pressure is marked by red.


More About Boiler Pressure Issues

Regular boiler servicing can help you avoid costly damage due to the pressure imbalance of the boiler. In this blog, you will be able to learn more about this issue.

Causes of Low Boiler Pressure

After regular use, your boiler tends to loses its pressure gradually. A sudden pressure drop in the boiler is a prominent sign of a system leak. However, you can get rid of this issue with regular annual servicing. The temperature of the circulated water will help you know if the boiler is operating at optimum pressure. The constant dripping of the water around the base is an obvious sign of low pressure.



To avoid low-pressure problems in your boiler, you can try various solutions. You must always re-pressurise the boiler system after bleeding the radiator. Though radiator bleeding benefits boiler heating, it can cause a massive pressure drop and require a top-up.


Causes of High Boiler Pressure

The pressure gauge of your boiler may reach the red zone, typically due to overfilling. It may also be caused by the issue of system faults. If you find your boiler automatically shutting down, you can be sure there is a problem. In such situations, you must call for an expert’s help.



If you don’t want your boiler to get affected by the high pressure, install a pressure relief valve. It lets the excess water escape, maintaining an optimum pressure balance inside the heating device. If the issue has been around for a long time, it is better to get professional help.

To keep your boiler running smoothly for years, it is important to keep an eye on the pressure gauge. For better assistance in treating these problems, contact a professional.
