Is Your Boiler About To Break? Here Are The Signs...

Boilers are at the heart of your home and as a result, are a complicated piece of kit. As a consequence, they can break from time to time. Occasionally they can break without warning, but most of the time they present some often-ignored warning signs, which if noticed, can help you prepare for the worst before its too late! Hence, we’ve compiled a list of signs to look for, for all of our customers across South Tyneside and the surrounding areas.

Sign #1 Cold Water

An influx of cold water rather than hot water through your taps/showerhead is perhaps the most obvious indication that your boiler is possibly in need of a repair. Sometimes it might just be a case of waiting for the water levels to resurface. If this still doesn’t fix the problem, it might suggest that the airlock has broken or the motorised valve has failed. Either way, this will require a heating engineer to provide a fix.

Sign #2 Pilot Light

If you have a gas boiler, look through the window panel and take a look at the colour of the pilot light. If the pilot light is blue, it shows that the flame is getting the correct level of oxygen expected for a properly functioning boiler. On the other hand, if the pilot light is orange, it indicates that there might be dirt clogging the connected air intake valve. An orange flame can result in the release of carbon monoxide through the central heating system. Hence, it is important to call a qualified heating engineer ASAP to fix the problem!

Sign #3 Low Water Pressure

Go to your boiler and take a look at the pressure gauge. Some boilers will have a red line on the gauge to indicate the pressure reading when it was first installed. As a general principle, the reading should show a figure of around 1. If the figure given is significantly below 1, it might indicate a problem with your boiler. Low pressure can stem from a leak in the system or from a faulty pressure-release valve that needs to be replaced.

Sign #4 Loud Noises

If your boiler is making strange ticking, gurgling, knocking or clunking noises, it often suggests that there is trapped air in the system. It is important to get this trapped air released before the problem intensifies. Loud noises are also a possible indication of imminent pump failure. It’s best to call out a qualified heating engineer so they can identify why your boiler is making a strange noise.

Sign #5 No Heat From Radiators

Radiators that fail to heat up can often be fixed through a quick bleed. However, if you find that you have to bleed them regularly, it might be a sign of a much deeper problem within the central heating system/boiler itself.

Sign #6 Expensive Gas Bills

If you have noticed that your gas bills are not a fair reflection of the gas that you have used, it might suggest that your gas boiler is no longer working as efficiently as it should be and somewhere along the line is losing/wasting gas. Of course, this can be tricky to tell and we’d always recommend talking to your energy provider first before worrying about a boiler repair/replacement.
