When heating pipes become very hot, they expand and cause pipes to shift slightly. However, when the pipes are situated on a hard surface, banging noises will be produced with the slightest movement on their expansion. Placing small pieces of foam near pipes that travel through wooden supports will prevent banging or other bumping sounds.
If this does not fix the issue, seek professional help by hiring residential heating services. You can also have a residential heating and cooling contractor to check your system and eliminate noisy pipes.

Kettling The term kettling refers to the sound that a kettle or pot makes as it heats up. Gurgling Gurgling in your radiator system is often a symptom of air bubbles trapped within your unit.
Back to News. This will swap the pesky hard water particles for safe sodium particles to prevent the future build-up of limescale. You can also improve the quality of your water and reduce limescale build up with an electrolytic scale reducer. This is a cheaper alternative to a water softener but still very effective way to prevent an annoying noisy boiler.
If you can hear your pipes making a thudding sound, the first thing you need to do is check the thermostat — either on your wall or your boiler. To do this properly, turn your boiler off and allow the system to cool down. One of the most common causes of banging pipework is that the pipes under the floor are not secured correctly. Copper pipes need to be properly secured in order to prevent them from rattling too much.
A simple solution, that should fix the problem of banging pipes, is to squash some felt around each pipe under your floorboards. Try and concentrate on every place where a pipe touches a joist or another pipe and wrap a little felt around it to create a snug fit.
There are a few reasons why you might have a noisy radiator or noisy pipes. The most common cause of a noisy radiator when the heating comes on is air trapped inside your system.
Apart from having a noisy radiator, another good way to check for trapped air is to feel the radiator. If it feels cold at the top but hot at the bottom, then there is trapped air inside.
You can easily solve the problem of trapped air in your central heating system by bleeding the radiators — watch the video below to find out how.
Another cause of gurgling in a heating system — particularly in colder weather — could be a frozen condensate pipe.
Colder weather can cause pipes to freeze, stopping water from circulating through the system. Your condensate pipe is normally a white overflow pipe that drains to the sewers outside of your home — and is usually found on an external wall outside of where your boiler is. If your condensate pipe is frozen, it is normally at the most exposed external point — at the end of the pipework and near to the drain.
As in the image above, you can normally thaw a condensate pipe out entirely with a little warm water. Using a suitable container — like a jug or a watering can — simply pour a little warm water onto the surface of the pipe to slowly thaw it out and remove the blockage.
Be sure NOT to use boiling water, as this can cause more harm than good, and once the contents of the pipe have fully drained and the blockage has been removed, restart your boiler. A tapping — or gurgling sound like the one described above — could also be caused by a build-up of limescale within the pipes and radiators. If you suspect this is the problem, use a non-acidic cleaner to flush out the system when the heating is turned off.
A humming sound coming from your heating could mean that the heating elements in your immersion heater are not functioning properly.
