A boiler that bangs, gurgles, or whistles is trying to tell you something, and each sound points to a different cause. Ignoring the noise usually leads to a bigger and more expensive repair.
The banging
A loud bang or knock from a hot water boiler can be trapped air, a failing pump, or, in a steam system, water in the steam pipes.
The gurgling
Gurgling often means air in the system or a low water level, which needs bleeding or a fill-valve check.
The whistling
A high-pitched whistle is usually a restricted valve or a kettling sound from scale on the heat exchanger.
The kettling
Scale deposits insulate the metal and let water flash to steam in spots, making a rumble. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In Champaign, hard water makes kettling more likely.
The annual
An annual service catches air, scale, and pressure issues before they become noises. A quiet boiler is usually a serviced boiler.
