Boiler making humming noise when heating on – is that normal? In short, yes. Your boilers circulating pump is what sends hot water around your house and it is fairly typical for you to hear some humming when using the heating or running a shower etc.
Why does my boiler keep making a rumbling noise?
Gurgling sounds in your boiler can be caused by low water pressure. The pressure gauge is usually found within the control panel. In some cases, it may be beneath the boiler where the pipes are connected. The correct pressure is usually marked on the gauge by a pointer or a green region - usually 1 - 1.5 bar.
How do you know if your boiler is overheating?
In many cases, the main symptom of an overheating boiler is a shutdown. Modern boilers will stop working immediately if they have become unsafe. Often this occurs when the boiler has overheated, and pressure within the boiler has risen to a dangerous level.
How loud should your boiler be?
Any sound 10 times more intense than silence, like breathing, hits 10db on the scale. A sound 100 times louder than 0db, let's say whispering, will be recorded as 20db. And so on. A modern condensing combi boiler has a sound level of somewhere between 40 and 60 decibels as it heats a home.
Why is my heating so noisy?

Why does my gas boiler make a clicking noise?
A series of clicking or tapping noises followed by not much will most likely mean your igniter is faulty or that there’s a problem with your gas supply. Either way, this is probably one of the more serious problems because it leads to the boiler simply not working.
How to tell if a boiler is loud?
Sound travels very well through pipes and so the problem could come from elsewhere. The easiest way to check this is to stand near the boiler while it’s working. If it’s loudest at the boiler then it’s probably the cause. If the noise sounds louder when stood near the pipes then it’s coming from elsewhere.
Why does my boiler have an airlock?
Much like any other appliance that deals with water, a boiler is prone to airlocks. An airlock is simply caused by – you guessed it – air in the pipes. This is particularly common on newly fitted boilers or when running hot water for an extended period.
Why does sludge build up in boilers?
It’s caused by breakdown inside the pipes, which is simply a result of water flowing through metal pipes, creating rust.
What does a boiler pressure gauge tell you?
Your boiler should have a pressure gauge that’ll tell you whether the pressure is correct. If it’s low, you might have a leak in the system, in which case you need to locate and identify the problem.
How to reduce boiler noise?
Possibly one of the easiest ways to reduce the overall noise your boiler makes is to replace it with a newer model. However, this is probably only applicable if your boiler is over 10 years old.
Why does my boiler make a noise?

Why does my boiler make a whistling noise?
Other causes of kettling in boilers include sludge or debris collecting around the heat exchanger or if a pump has become stuck or needs to be replaced. Kettling could have damaging long-term effects on your boiler by reducing its efficiency.
Why does my boiler kettle?
The most common cause of boiler kettling tends to be an accumulation of limescale on the boiler’s heat exchanger. Within the UK, some areas tend to have ‘hard water’ which is a term used to describe H2O that possesses high mineral content such as calcium and magnesium. Places such as London, Bristol and Southampton are known to have a degree of hard water that ranges from hard to very hard.
How to check boiler thermostat?
Check your boiler’s thermostat by turning off the boiler and cooling the system down. Once cool, turn it back on again and turn up the thermostat. It should click. If not, it may be time to call for a Gas Safe Registered engineer.
Why does my radiator gurgle?
Gurgling noises. Gurgling radiators could be the result of trapped air in the system, low water pressure, or a frozen condensate pipe. It is fairly common for a small amount of gurgling within the boiler, however it’s important to investigate further if this becomes loud or constant.
How to tell if boiler is low pressure?
Check the pressure gauge on the boiler in case you have low water pressure causing the gurgling noise. Always refer to your user manual, but typically if the reading on the display is below 1 bar, this is a sign of low pressure. To increase the pressure to the correct level follow our step-by-step guide.
Why does my water pipe rattle?
Sometimes, banging pipes are simply due to pipework not being secured properly under the floor; if you’ve always heard rattling noises, then this may be the case. This can make them rattle around when water is flowing through them. One of HomeServe’s engineers could help solve this problem, simply contact us to arrange an appointment.
How to tell if boiler is making noise?
One of the first things to check when your boiler is making noises is your boiler pressure gauge. You can usually see this if you take a look at the underside of your boiler. Normal pressure is between 1 to 1.5 bar. If your gauge is reading lower than this you can easily re-pressurise your boiler yourself. To do this take a look at your boiler manual for instructions.
Why does my boiler make a humming noise?
If your boiler is making a humming noise or vibrations when the heating is on, it could be due to a build-up of sludge or limescale. This can often happen in older homes, or if you live in an area with hard water.
How to check if a boiler is leaking?

Why does my boiler make a loud bang?
So what’s causing that noise and is it dangerous? If your boiler makes a single BANG only when it fires up, it’s most likely due to delayed ignition. If your boiler makes recurring banging, popping noises as it operates, it’s most likely due to “ kettling ”.
Why does my boiler have steam bubbles?
Water temperature on boiler is set too high. Setting your boiler to a very high temperature can overheat the water, causing steam bubbles.
Why does limescale overheat?
As the layer of limescale builds on the heat exchanger, it acts as a barrier between the heat exchanger and the water. Because the water is much slower to heat due to this barrier, the burners stay on longer , causing the heat exchanger to overheat.
What does it mean when a boiler is keetling?
Kettling can happen in any kind of boiler. It essentially means that your boiler’s heat exchanger (the part that actually heats the water) is too hot. When this happens, water that comes into direct contact with the heat exchangers gives rise to tiny steam bubbles.
What happens when water pressure is too low?
Water pressure/flow is too low. When the water pressure/flow is too low, water runs over the heat exchanger much slower than it should. This slower pace causes the water to overheat, giving rise to steam bubbles which erupt forcefully when they reach cooler water. Bad thermostat.
Can a gas furnace crack?
Have a professional examine your furnace as soon as possible. If ignored, the intensity of the flames caused by the gas buildup can eventually cause your boiler’s heat exchanger to crack (easily a $1,200+ repair).

Why does my boiler keep tapping?
If tightening any loose parts doesn’t solve the problem, the tapping could down to a build-up of sludge or limescale on the heat exchanger. As explained in the banging boiler section, these build-ups need to be resolved by a professional performing a powerflush of the system.
What is the job of a central heating pump?
The pump’s job is to force the water through the system from the boiler to the radiators where they’re needed. A lot of central heating pumps come with three speed settings, and if yours is set too high it may create that humming sound you’re hearing.
Why is my heat exchanger bleeding?
If bleeding the radiators doesn’t sort the problem, then a build-up of dirt on the heat exchanger is the likely culprit. You’ll need to get a heating engineer in at this point to perform a powerflush.
Why does my heat exchanger make a whistling noise?
It’s caused when limescale builds up on the heat exchanger. Once it happens, it isn’t something you can sort on your own. As with other issues, you need a heating engineer to perform a powerflush.
How many different boiler noises are there?
We’ll run through 7 different boiler noises, what they mean and how to fix them (if required).
Why does my boiler make a noise?
A faulty boiler thermostat that allows water to overheat and boil can also cause disturbing kettling noises. In some cases, the thermostat may simply be set too high and lowering the temperature will solve the problem. If your system’s heat output decreases after doing so, have your heating professional check whether your thermostat is defective and needs replacement.
Why does my boiler make a banging sound?
If air gets into your system, pressure differences in the tank can cause knocking and banging sounds in the radiators and pipes. Air can infiltrate the boiler system through faulty valves, the expansion tank or leaks in the pipes and connections.
What does it mean when a water tank makes a noise?
As these bubbles move upward and dissipate in the cooler water near the top of the tank, they make a loud rumbling or percolating sound known as “kettling.” To quiet things down, add a descaling product to dissolve the mineral buildup, and then drain and refill the tank.
What happens when water in boiler overheats?
When the water in your boiler heats up, naturally-occurring minerals precipitate out and settle at the bottom of the tank. If the buildup restricts normal flow inside the heat exchanger, water trapped inside overheats and begins to rapidly boil and bubble.
