Boilers are essential to heat our homes, but sometimes things can go wrong. Jacqueline Gallazzi-Ritchie, Director of All England Gas, told us what to do if we encounter some of the most common boiler problems.
Buying your first home is exciting, but knowing how everything works can be daunting, and it’s even worse when something fails. We rely on our boilers to heat our homes and water, but do you know what to do when things go wrong? I’ll be giving you my expert advice on how you can deal with the most common boiler problems.
No heating or hot water
If you find yourself with no heating or hot water, check that the time and temperature settings on your boiler haven’t been changed by accident. If everything seems fine, it could be an issue with the diverter valve, which sits inside the boiler and switches between hot water and heating. Sometimes it can stick between the two and you don’t have either of them. You’ll usually only know if there is a problem with it if you’re not getting any heating or hot water and you should always call a Gas Safe engineer instead of trying to locate and fix it yourself.
Radiators aren’t hot
This is a very common boiler problem and is usually because the system has filled with air. It’s easily solved by bleeding the radiators. To do this, you should have a key which can be inserted into a valve at the side of the radiator. Turn it until you hear a hissing sound, which is the air escaping, and turn it back when the hissing stops and water leaks out.
Boiler is leaking
If your boiler is leaking, check the pressure gauge is in green: if it’s too high, the pressure relief valve will let some water out to reduce it. High pressure can often be caused by limescale and you should call a Gas Safe engineer to remove it. Alternatively, the leak could be due to a damaged pipe or seal, which will also require a Gas Safe engineer.
The pilot light is out
The pilot light is the flame that burns at the bottom of your boiler — the casing often has a little window so you can see it. Usually, this should burn a crisp blue colour, but sometimes it can turn orange or go out completely. If this happens, gas can quickly escape, and you should call your Gas Safe engineer immediately.
Never open the cover of the boiler or try to repair boiler problems yourself. You should always call a Gas Safe engineer to conduct any repairs.
