Why does my boiler make banging noises?
Kettling is when your boiler makes banging or popping noises when turned on. It is commonly caused by a build-up of limescale or corrosion debris on the surfaces of the heat exchanger. This build-up can restrict the flow of water and cause localised boiling, which can cause hot water to turn into steam.
Why is my boiler making a strange noise?
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. Kettling is more likely to occur in older boilers with cast iron heat exchangers, particularly in areas with hard water.
Why does my central heating make a rattling noise?
If your central heating makes loud rattling noises, that usually indicates there are loose objects shaking or vibrating against one another, but if that’s not the case, there are a few more reasons why this could happen. Sometimes, rattling noises from a boiler are the result of air in the pipework.
Why does my water heater make a rumbling noise?
Water heaters can also cause rumbling noises due to bits of sediment, rust or limescale heating up and expanding within the cylinder. Rumbling noises can also stem from very high pressure. If the incoming main water supply has too much pressure, valves inside your house can hum or whine, so it’s important to check if you need to readjust.
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.

What should I do if my boiler makes a gurgling sound?
In some cases, a gurgling sound may be mistaken for the sound of water boiling within – this is unlikely to be the case so don’t panic. Take the following steps to diagnose and eliminate the problem, if you are confident to do so: 1. Bleed the system
