Why is my boiler making a loud bubbling noise?
The most common reason for a gurgling sound is air trapped in the system or a blockage at the base of your boiler. This trapped air may also be accompanied by cold patches on a radiator. You should also check your boiler pressure in case you have low water pressure causing the gurgling noise.
Is a bubbling boiler dangerous?
Kettling has the potential to be dangerous, as theoretically the high pressure could burst internal pipework and cause steam emission and electrical hazards. However, modern boilers should have built-in safeguards to detect the symptoms of overheating and shut down the boiler before it reaches that stage.
Why does my boiler make a tapping noise when I turn it on?
You’re more likely to experience a tapping noise when you first turn your boiler on. Kettling is caused by a build-up of limescale in your system preventing the natural flow of water as it is pumped around your central heating system. Kettling resulting in a tapping noise is more likely to be located in your system’s pipes or radiators.
Why does my boiler gurgle when I Turn on the water?
If the water pressure is too low, this may be the culprit of your gurgling noises. Your boiler will have a pressure gauge, also known as a manometer, located in the area where the pipes are connected to the boiler itself.
What to do when your gas boiler starts to Rumble?
When it begins to start rumbling, turn on one hot water tap, and tell me if that stops the rumbling. Watch the pressure gauge from when you first turn it back on, until first rumbles and tell me what happens with the gauge pressure.
Why do I hear a whistle coming from my boiler?
The trapped water will heat up too much, start boiling and eventually turn into steam and expand, which is why you may hear a whistling noise. It sounds simple but you won’t be able to fix this one yourself, so you’ll need it to be checked out by a qualified engineer.

What should the pressure be on my boiler to make a humming noise?
A healthy boiler will never exceed 12 to 15 psi (pounds per square inch). If your boiler is over 15 psi, the higher-than-normal pressure can cause a humming/buzzing noise.
Why do I have steam bubbles in my boiler?
Water temperature on boiler is set too high. Setting your boiler to a very high temperature can overheat the water, causing steam bubbles. Have a professional inspect your boiler to determine what’s causing your boiler kettling. They’ll fix the problem to get your boiler back to normal, quiet operation.
