boiler noise

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.

    Oh no... another boiler noise question!

    We have a Vaillant Ecotec 415 system boiler, about 11 years old. It has been serviced annually (most recently in Sept 2021) and we've had a couple of issues with odd noises in the past (once just after servicing), but these have been resolved by a heating engineer tweaking something or other -...

    High pitch noise from boiler flue

    Hi, My boiler has started making a very high pitch noise when the heating turns on. It seems to be originating from the boiler flue (see video https://bit.ly/3pYMFrI ) Is this an indication of air trapped in the system ? Do radiators need bleeding ? Or a sign of faulty boiler part ? Thanks
