A noisy boiler could be an indication of many problems in your central heating system. If you do have a noisy boiler then it is definitely not a problem that you should ignore for any length of time. A small problem left untreated could soon turn into a much bigger problem. A noisy boiler issue could easily escalate into you needing a whole new boiler. This is incredibly expensive and something you should generally want to avoid.

If you do have a noisy boiler then it is normally best that you call an engineer to come and investigate the issue. A highly skilled engineer is definitely the person you want in your home in the event of any central heating problems and they should be able to diagnose the problem for you with little difficulty. If you have a noisy boiler but don’t have immediate access to an engineer then there are a few checks you can conduct yourself first.

Firstly if scale has built up in your central heating system then it will cause bubbles of steam that could be responsible for the noisy boiler. To rectify the situation you simply have to turn your system off, add a chemical descaler and leave it alone for 2 or 3 days (according to instructions on bottle) and then flush the entire system.

Secondly, if you’ve set your boiler thermostat too high then this could be the cause of your noisy boiler. If the thermostat isn’t the reason behind your noisy boiler then it could be that you don’t have enough water flowing to your boiler. This could be due to a number of things but will most commonly result in a noisy boiler. You can manually check your water flow rate and your float valve but it is ardently advised that you let an engineer do this.

The noisy boiler could also be the fault of low water pressure. If your central heating system is experiencing low pressure then there should be an indicator to make you aware of this.

Regardless of what you think the cause of your noisy boiler is you can save yourself a lot of time and unnecessary effort by quickly consulting a professional. They will be able to tell you why you have a noisy boiler and put things right for your boiler in no time.
