Why is my boiler making a clunking noise?
So why is your boiler making noise? Clunking and banging noises are called 'kettling' noises, and are caused when limescale accumulates on the heat exchanger. This blocks the flow of water and causes some water to boil, steam and expand, as seen in a kettle and so your boiler could be making loud banging noises.
Why does my boiler make a banging noise when firing up?
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.
Will 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.

Can a boiler explode if turned off?
When boilers are sealed off, some water will remain and will eventually be heated to form steam, creating pressure. As internal pressure builds up, the jacket can explode because of the lack of water.
Is a boiler safe when switched off?
Fortunately, switching off your boiler at the mains is perfectly safe. That being said, depending on the type of heating system that you have and how old it is, switching it off for long periods of time could trigger an issue with your central heating.
What happens when a boiler overheats?
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. To stop pressure rising so far that the unit explodes, the boiler will stop working.
What happens if too much pressure in boiler?
If the boiler pressure is too high, there's an increased chance of leaks developing in the system. But if boiler pressure is too low, the system won't work as well. So keeping the correct boiler pressure is important to make sure that your system heats your home efficiently.

Why does my boiler have bubbles?
Water temperature is set too high. Setting your boiler to a very high temperature can overheat the water, causing steam bubbles.
What does it mean when a boiler is keeling?
Kettling means that your boiler’s heat exchanger (the part that actually heats the water) is too hot. When this happens, water that comes in direct contact with the heat exchangers causes tiny steam bubbles. As soon as those bubbles drift away from the heat exchanger into cooler water, they burst—creating that persistent banging/popping noise you hear.
Why does limescale build up on heat exchangers?
When 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. And when this happens, small pockets of water trapped between the heat exchanger and the limescale heat up to the point of steam bubbles (which burst as they escape).
How to tell if radiators need bled?
Step 1: Turn your heat on and wait until your radiators have reached max heat. If you run your hand near the top of your radiators and feel any cool or cold spots, that's a sign that your radiators need to be bled.

Why does water overheat?
This slower pace causes the water to overheat, which in turn causes steam bubbles to erupt when they reach cooler water.
What happens when debris builds up in a boiler?
The build up of debris can lead to a restriction in the flow of water, causing a reduction in boiler efficiency and heat distribution.
How long does it take for a boiler to quiet down?

Why is my boiler kettling?
Kettling isn’t a process of retraining for your boiler because it fancies a career change, kettling is caused by a build-up of limescale or sludge on your boiler’s heat exchanger. This build-up restricts the flow of water in the heat exchanger, overheating the water, causing a noise like that of a boiling kettle to occur.
How to release trapped air from radiator?
Solution#N#To release trapped air all you have to do is bleed your radiators by following these steps: 1 Switch off your boiler and let it cool completely 2 Find the filling loop (flexible silver cable) and make sure both ends are tight or you may have an internal filling key but it’s the same principle. 3 Open bath valves or turn your internal filling key to allow cold water into the system, this will repressurise the system. 4 When the gauge reaches 1.5 bar close both valves. 5 Remove the filling loop if it isn’t a permanent attachment. 6 Turn the boiler back on. 7 Check in a few days to see if it has lost pressure again.
