Abnormal noises in a boiler should not be ignored, as they may indicate an underlying problem. These noises can affect the proper operation of the unit, and ultimately damage its components. So it’s important to identify the cause quickly and take the necessary steps to remedy the situation.

Different types of boiler noise

Abnormal noises can vary depending on their origin. There are several common types of noise you may encounter, each with a different cause.

Lapping” or “gurgling” sound

This noise resembles a buzzing or splashing sound. It is often due to the presence of air in the heating circuit, preventing normal water circulation. This phenomenon is common when air accumulates in radiators or pipes.

What can be done about it?
Bleed your radiators to release trapped air. If the noise persists, it may be necessary to descale the system to remove sludge and other deposits from the pipes.

Whistling” sound

A whistling noise may be caused by low water pressure or insufficient water flow. It can also be the result of a dirty or clogged filter, which impedes the flow of water through the boiler.

What can be done about it?
Check your boiler pressure and adjust it if necessary. Make sure filters and valves are clean and working properly. Regular maintenance will help prevent this type of problem.

Clicking” or “clacking” noise

This noise is often due to internal boiler components deteriorating or moving parts becoming unbalanced. It can also be caused by rapid temperature variations, causing metal parts to expand and contract.

What can be done about it?
We recommend that you call in a professional to check the boiler’s internal components and repair or replace them if necessary.

Flapping” or “water hammer” noise

A “pounding” noise can occur when there is a rapid change in pressure in the heating system. This phenomenon, often referred to as “water hammer”, can occur when the water flow is suddenly stopped or altered, creating a shock wave.

What can be done about it?
A professional can check the pressure regulation system to make sure it’s working properly. Shock absorbers or pressure regulating valves can also be installed to prevent this type of noise.

When should you call in a professional?

If the noise persists despite your attempts to repair it, or if you notice any other anomalies, it’s essential to call in a qualified heating engineer. Abnormal noise may be the sign of a more serious problem requiring technical expertise.
