Boiler Noises

Now and again there may be strange noises coming from somewhere in the home that sounds like the bubbling of water for example. The chances are that the sound will be emanating from your central heating boiler. This could be due to a few things, however, if the has been working well and the problem has only just started for no apparent reason, it is possible that a narrow pocket of air has become trapped within the boiler, perhaps due to internal corrosion. An N9 Plumber can find corroded pipes.


The noise is produced by the formation of steam and its subsequent condensing in the area where the air is trapped. The best remedy, apart from buying a new boiler, is to use a descaling solution. If a power flushing of the system is needed this would really require the services of a reputable heating and plumbing engineer, like N9 Plumbers. However, it depends on how old your system is and the materials it is made from, like aluminium, copper or steel. Chemical cleaning solutions, available from most plumbers merchants. These come with the necessary application instructions to clean out your system. It should be noted that using these acidic solutions will clear sludge that could been blocking a corroded radiator and preventing it leaking. So there is a chance that it may expose the fault and leave you with leaks. However, at least you will find the leaks under a controlled condition and The noise from the boiler may, however, not be due to trapped air but could be due to impingement of the flame directly onto the heat exchanger within the boiler, causing local hotspots where steam forms and collapses. This requires a specialist heating engineer to make the necessary adjustments to the flames and, where necessary, to investigate the cause further.
