Have you ever sat down in a quiet room only to be interrupted by clanking, gurgling or whistling from your heating system? Many homeowners in Trowbridge ask the same question: Why is my radiator making a noise? Not only can these sounds be irritating, but they can also be a sign that something isn’t quite right with your central heating system.
Common reasons your radiator makes noises
Radiators can produce a variety of sounds, each pointing to a different issue. Understanding these noises can help you decide whether a simple fix is enough or if you need professional central heating repairs in Trowbridge.
- Banging or clanking often comes from trapped air or loose pipes. As hot water flows through, it causes expansion and vibration.
- Gurgling is usually a sign of air pockets inside the radiator. This is one of the easier issues to resolve, often with a quick bleed.
- Whistling or hissing could point to a faulty valve, where water flow is being restricted.
- Knocking may be caused by ‘water hammer’, where fast-moving water hits against pipework bends or valves.
How to fix minor radiator noises
Some issues can be tackled by homeowners with basic tools. For example, bleeding your radiator to release trapped air is a straightforward job and often stops gurgling. Similarly, ensuring the radiator valves are open and balanced can reduce whistling.
However, if you find that bleeding doesn’t work or the noises return quickly, it may indicate a deeper issue within your central heating system. In this case, it’s always best to bring in a qualified heating engineer to conduct a thorough investigation.
When to call a professional
While some radiator noises are harmless, persistent or worsening sounds should not be ignored. They could point to:
- A failing pump putting strain on your system
- Sludge or limescale build-up restricting water flow
- Poorly installed or ageing pipework
- Faulty radiator valves needing replacement
Left untreated, these problems can reduce efficiency, increase energy bills, or even cause breakdowns. That’s when it’s worth calling in an experienced heating engineer for professional advice and repair.
Preventing noisy radiators
Prevention is often better than cure when it comes to heating systems. Regular servicing keeps your boiler and radiators running smoothly, helping to reduce the risk of noises developing in the first place. Power flushing can also clear out sludge and debris, giving your system a fresh start.
By booking an annual boiler service with AN Heating, you can keep your system in good condition and avoid common issues that lead to noisy radiators.
