CSN News: Radiator rackets: How to identify and fix the strange sounds –

These noises can be caused by many different things and are often fixable by identifying their source. To begin, note when the sound occurs. As an example, when the heating system is on, the hot water will move through the pipes towards the radiators. This can produce various sounds.

When materials expand, they make a metallic sound. If it is louder or occurs more frequently, this could be a sign of a system problem. Air trapped in pipes can also cause noise. Air bubbles can be created as hot water flows through the pipes, causing noise. Radiators can be bled to solve this problem.

Different Radiator Sounds, Different Problems

It’s possible that you are hearing sounds even though the heating has been turned off. The valves may not be completely closed or water could still be circulating. Even when the heating is off, temperature changes can cause materials to expand and contract. This will create noise. Check the boiler pressure if bleeding radiators does not work.

Different sounds can indicate different problems. By bleeding the radiators, you can usually fix gurgling noises caused by air in the system. Metallic sounds are usually caused by temperature fluctuations, but can also be a sign of loose or poorly installed parts. If you hear drips, it could be a sign of a leak. Also check the connections for any moisture or leaks. Whistling usually indicates low pressure in the water, which can easily be adjusted by the boiler.

It’s a good idea, if you’re not sure, to consult an expert.
