Why is my boiler making a banging noise in Glasgow?

Banging from a boiler or heating system can have several causes, including poor circulation, trapped air, pump issues, scale or sludge, rapid temperature changes or a component fault. The exact timing of the noise is useful: note whether it happens when the boiler first fires, when it shuts down, or while radiators are warming.

Older Glasgow heating systems can contain accumulated debris that restricts flow, but noise should not automatically be blamed on sludge. A proper diagnosis should check the boiler, pump, valves, system pressure and circulation before deciding whether cleaning or parts are required.

If the noise is new, severe, accompanied by leaks or followed by a lockout, switch the appliance off and arrange an inspection. Doherty covers boiler repairs and heating-system work in Glasgow and can identify whether the noise is coming from the appliance or elsewhere in the system.
