My Boiler is Making Noises it Didn't Make Last Year
Updated: Jun 5
Boilers should be seen and not heard.
When something's wrong with your gas boiler, you'll probably hear about it. A noisy boiler is one of the most obvious (and annoying) warning signs that your heating system is in need of repair or replacement.
The first step is to determine why your boiler has suddenly started making these strange sounds—and the answer to that usually lies in the type of noise it's making:
If your boiler is making a whistling noise that reminds you of a hot kettle on the stove, that's a sign that air might be trapped within the system. The solution is often as simple as releasing the air, and finding out what trapped the air in the first place.
If your boiler is making gurgling sounds, there might be blockages at the bottom of the boiler, low water pressure, or trapped air. If the weather's cold, it might even be a frozen condensate pipe that will need to be thawed before proper functionality can be restored.
Banging or clunking
If your boiler is making a banging noise or clunking sounds, there might be a buildup of limescale from hard water or debris from corrosion in the system, which might be blocking the safe travel of water. This is known as "kettling." Left untreated, kettling can lead to a buildup of steam, which expands dangerously inside the unit with nowhere to escape.

Is my boiler unsafe?
Boilers contain pressurized hot gases and liquids. For that reason, it's always better to be safe than sorry. Never ignore signs of disrepair or damage to your heating system, or delay a consultation when you're experiencing problems.

Ongoing deterioration of your boiler's interior

What are other signs that my boiler might need to be repaired or replaced?
Some symptoms of boiler damage or disrepair aren't as obvious as weird noises. The following issues might mean your heating system is overdue for maintenance:
Unusually high heating bills
Lack of or reduced hot water output
Poor heat distribution, or changes in how efficiently your home heats
Leaking or dripping
Your boiler is more than 15 years old
Proper maintenance of your boiler goes well beyond a safety issue. When your boiler isn't working as efficiently as it should, it uses more fuel to reach the temperature your thermostat is set to. This results in an increase in energy usage, and consequently, an increase to your monthly energy bills. An overworked boiler also has a shortened lifespan. By delaying a repair, you might actually end up having to replace your boiler before its time would normally be up.
