Boiler Pressure Explained

We often get call outs from customers with boiler issues and, more often than not, the root of the problem is due to low boiler pressure. But what does this mean and how can you resolve it? We will give you an overview below so that you can feel more informed if such an error occurs with your boiler at home.

First, you need to understand where your boiler pressure gauge is on the boiler itself. Once you’ve located that you should know it should be sitting between 1 – 1.5 bar. Anything below this it is too low and could cause the boiler to cut out. If it’s higher than this, you should call out a boiler engineer as soon as possible.

Low boiler pressure can be a result of a water leak or a recent radiator bleed. Whilst it’s not dangerous to have low boiler pressure it is important to get it rectified, to ensure your boiler continues to operate properly and doesn’t cause any long-term damage. If it is left ignored it could have an impact on your boiler’s lifespan and overall efficiency.

It is possible to repressure the system yourself; you need a filling loop and turn off your boiler whilst you repressure. Whilst it is possible to do it all yourself, we would always advise that you contact a gas engineer to ensure it is completed safely. They will also be able to identify if your boiler is in need of any other servicing at the same time.

One way to ensure that your boiler pressure continues to be at the appropriate level is to book in a regular boiler service. We advise our customers to service their boilers annually to help keep it in check. Boiler services are a chance for the engineer to spot any defects before they develop into larger problems. Checking the boiler pressure is part of this service and if spotted early is usually easier to resolve.

Boiler pressure isn’t anything to be too scared of, but it is something you should be aware of. If your boiler does start to cut out, check the pressure first and pass this information onto your gas engineer who can help them diagnose the problem quicker.
