Are you experiencing things that go bump in the night (and the day for that matter) What is causing your noisy boiler? This is the question that many people ask when they notice that their boiler is making quite a lot of “noise.” What exactly is this noise? The noise is the sound of anything vibrating or clunking or even a sound like a kettle boiling. This is known as ‘kettling’ and is a sign that all might not be well inside your boiler.
Kettling occurs when the flow of hot water is slowed down for some reason. As the water reaches high temperatures, it cannot escape it into the pipes quickly enough and so creates steam which then gets trapped in the system. The restriction to the speed of water flow is usually the result of a build up of sludge on the heating element. You might experience a whistling sound, like that of an old fashioned kettle boiling.
The best option is to call in a professional who will be able to identify any issues quickly before any further damage is done. For Boilers Gloucester, go to a site like HPR. Kettling will usually require a power flush to fix. A power flush is able to blast away any bits of debris or limescale build up to improve circulation.
Boilers should run smoothly, with nothing unusual being heard aside from the normal operating hum and sounds of the boiler firing up when you put the heating on. Any other strange bumps, clangs or rattling coming specifically from the boiler should be reason enough to get it checked by a gas engineer to avoid problems becoming worse and more expensive down the line.
If you are hearing a vibrating noise inside the boiler, this is most likely down to a loose component that needs tightening. It could also mean that a component is broken, damaged or has become detached. This is a job a homeowner can attempt themselves, if it is just a case of tightening wall brackets and closing anything that may have opened. However, if the entire boiler unit is vibrating then this is a job for a professional. It could be a sign that the central heating pump has been set too high for your property.
Hearing a dripping sound is indicative of a leak somewhere inside the system. Wear and tear may have caused older components to break down or perhaps the pressure inside the system is too high. Either way, now is probably a good time to consider contacting a boiler service.
Gurgling sounds are a sign of air in the system. Trapped air can prevent the normal flow of water, slowing down the hot water reaching different areas of your home. This is noticeable by having radiators that remain cold even when the heating is on. Thankfully, this can be a quick fix and simply requires radiator bleeding on affected radiators.
