Common Boiler Problems and Their Causes

It can be a real worry if you suddenly start experiencing problems with your boiler. However, there’s no need to panic! With the majority of boiler problems, it’s often quite easy to work out a potential cause. Below, we’ve outlined the most common boiler problems, their causes, and the steps you need to take next.

No heat or hot water

This is one of the most common boiler problems! Not having access to hot water can be a real pain, so it’s a good idea to look into it as soon as possible. Problems with boiler heating are often caused by broken airlocks, issues with the thermostat or low water levels. To fix this, start by looking into the boiler pressure and the thermostat. If you can’t work out what the problem is, it’s a good idea to call out a heating engineer.

Leaking or dripping 

The cause of the leak will depend on where the water is leaking from so the first step is to locate this. Leaking often occurs because of a broken internal element or as a result of your boiler pressure being too high. However, if the boiler is leaking around the pipes or tank, this might be due to corrosion. Either way, you should never try to fix a leaking boiler yourself! Always call out a gas safe engineer to properly investigate the situation and if you need a boiler service in London, contact RyGas today.

Strange noises

Strange noises coming from the boiler can be quite worrying! However, it is a pretty common problem. Unusual noises are frequently caused by air in the system or low water pressure. In older systems, it can be an indication of pump failure. Sometimes, you can determine the type of problem by the specific noise – for example, whistling might indicate a build-up of limescale or trapped air, while banging could mean a problem with the fitting of your pipes. It’s a good idea to ring a reputable boiler service in London and provide a description of the noise – then they will be able to help you from there.
