How to identify the source of boiler noise

Boilers are essential appliances in any home and most of the time we take them for granted. They heat the water and the radiators in our homes and perform a crucial role in the comfort and safety of our homes. When we hear noises coming from the boiler it can be worrying, so read on to find out what these noises could mean.

Noises from the boiler can mean many different things. The first thing to do is to identify the source of the noise. It is possible for noises to travel through the heating system, creating echoes. You need to check if the noise is coming from the pipes, the radiators or the boiler itself.

Boiler fault codes

Many boilers have error codes on a digital display which can alert you to the problem. Check the product manual for more information about this. The fault codes are usually on the fault identifier pages of the manual or you could check them online. Not every problem will create an error code though, so you might need to do more checks.

Bleed the radiators

If you hear gurgling noises coming from the boiler, this means air is trapped in the system. You can open all the thermostats on the radiators fully and heat the home at the highest temperature for 15 minutes. Turn off the circulation pump and wait for the radiators to cool. Then bleed the radiators until water comes out. For more information on how to bleed a radiator, browse this handy guide form the Independent.

Circulation pump

The problem could alternatively be the circulation pump. If the pump is working too quickly, it can make noises. You might be able to slow it down if there is an option on the boiler, otherwise it might require a professional. For example, a high quality Gloucester boiler service such as http://www.hprservicesltd.com/gloucester-boilers/boiler-service-gloucester/ will be able to check your boiler and deal with any problems.

Water pressure

Another option is the water pressure of the boiler. If it is set too low, it can cause gurgling noises. The pressure gauge or manometer is located where the pipes meet the boiler. Make sure the pressure is at the right level by checking the manual against the pressure gauge marker. You might need to add more water to adjust the pressure.
