A broken boiler will have many knock-on effects that you might not even realise or notice. Ultimately, it could cost more to run, potentially leaving you without heating in the winter and even worse, with a dangerous boiler. So, with this in mind, how do you know which boiler issues are minor and which are a cause for immediate action? In this post we take a look at the most common boiler problems and give all of them a priority rating. ‘Low’ signifies it’s a minor issue, ‘High’ means you’ll need an engineer ASAP.
Average boiler pressure should sit comfortably at a 1.5 bar (this is applicable to boilers that work on a ‘sealed system’). If you’re experiencing a few problems getting heating from your boiler, in most cases pressure is the culprit. It’s easy to diagnose through checking the boiler gage and is straightforward to fix in a few easy steps. Losing your pressure is an inconvenience but by no means life-threatening.
A broken thermostat is by no means dangerous, but it is highly inconvenient. However, by making a few straightforward checks, such as checking that the timings have not been accidentally changed or the temperature settings adjusted differently, you might be able to find the cause of the issue. Attempt increasing the temperature on the thermostat and see if it triggers the boiler into action. If it doesn’t and the thermostat seems to have become less accurate, or started doing its own thing, it might be time to replace it.
Gurgling, banging or whistling sounds should in most cases be looked at, particularly if they don’t stop. They’re likely to be caused by air or a build-up of material inside your central heating. It’s not a dangerous situation but if left unattended, a build-up could lead to a boiler breakdown and expensive repairs.
Low pressure is a thermostat issue, or it could well be a lack of water in the system which could cause your boiler to switch itself off. If you are unable to identify the source of the problem, a Gas Safe engineer will certainly be able to do this for you. As with any boiler fault, it’s better to nip it in the bud.
Water coming from your boiler is always a negative sign. If you do, it might be a sign that an internal part of it has failed. Although this is not necessarily dangerous, you should switch off your boiler to stop your electrics short-circuiting and prevent water damaging your home or belongings. Don’t attempt to fix a boiler leakage yourself. Always let an engineer deal with it.
A pilot light turning orange or yellow could be an indication of poor combustion, in which case, this is very serious. It’s advisable that you turn off your boiler immediately and have a Gas Safe engineer come and look at it. If this is combined with the light going out, you definitely need to seek the services of an engineer.
