A noisy boiler can be down to a number of things. Sometimes it is perfectly normal for a boiler to make a noise, such as when the pilot light is ignited or when the pump circulates water around the boiler’s burner and heat exchanger. However, there are other times when a noisy boiler is a cause for concern.
When should I worry about boiler noises?
If your boiler is making loud banging noises, it may be the result of a faulty thermostat or a build-up of debris on the boiler’s heat exchanger. If there is a build-up of debris, you’ll need a qualified professional to carry out a power flush.
Why is my boiler suddenly noisy?
If the boiler’s heat exchanger contains debris, the boiler can overheat and generate steam, a process called kettling. This is why it begins to make a whistling noise, much like a kettle when it comes to the boil. When kettling is left, the problem can get worse and your boiler may eventually break down altogether.
Do modern boilers make noise?
Modern boilers have information coming from thermostats and the control panel, and this triggers switches and valves inside the boiler as components are switched on and off and water is redirected. Although they are usually silent, you might hear them from time to time.
Why does my boiler sounds like an Aeroplane?
If your boiler is making hissing noises; then your boiler is probably kettling. This can cause the boiler to overheat. There are many reasons for kettling, one is an increase in limescale inside the tank. Limescale can result from having water with excess calcium and magnesium in it that can build up over time.
Why is my boiler so noisy at night?
Boiler noises can be caused by low water pressure, the air in your system, mineral deposits, and problems with your water temperature. Before you go any further, make sure you have a good idea of the cause of the noise and what needs to be fixed.

Why is my boiler vibrating loudly?
This can range from something as simple as loose brackets – which is an easy DIY job – to a problem with internal parts, such as worn pump bearings, faulty burners or the boiler fan itself. If tightening brackets doesn’t get rid of the buzzing/vibrating noise, then it is likely that one of these problems is the cause.
What does air in boiler sound like?
Gurgling/ Dripping
The gurgling noise of the boiler sounds similar to the ones in your water pipes or taps, so it wouldn’t be strange to assume that you have a plumbing problem over a heating one. However, if you hear something bubbling or dripping near your boiler, it probably is.
Can my boiler explode?
While historically, boilers would over-pressurise and explode with alarming regularity, modern boilers are manufactured to be able to withstand excessive pressure, and can typically handle an operating pressure of 20 PSI. When pressures increase beyond this level, the boiler can fail, which can lead to an explosion.
Why does my boiler sounds like a helicopter?
Kettling is when a build-up of limescale causes the pipes (usually at the boiler) to ‘ping’ and rattle – or, in our Rayburn’s case, to sound like the boiler is playing the bongos.
How noisy are combi boilers?
A modern condensing combi boiler has a sound level of somewhere between 40 and 60 decibels as it heats a home. Similar to moderate rainfall or the average library.
Why is my heating system so loud?
When heat hits the cold metal ducts, it causes expansion. When the heat cycle finishes, the ducts start to contract which may produce a loud bang. While these noises from your ductwork can sound concerning, there’s usually nothing wrong with your ducts or ductwork system – it’s just a normal sound.
Should I hear my heater?
Unless you are right next to the furnace, you should not hear the actual sounds of the furnace running. If you can hear the sound of the blower motor, blower motor fan, or other types of noises throughout the home, it could indicate something is wrong with your furnace.
