When you have a gas boiler in your home, it’s likely that you will need to troubleshoot and repair it at some point. Having the right information can help you to diagnose and solve most common problems associated with gas boilers. If your gas boiler isn’t working as it should, there could be a variety of reasons for this. Gas boilers are complex machines with many different moving parts that all need to be functioning properly in order for the boiler to operate correctly. Sometimes, one problem can cause another issue and even if only one component is faulty, it could have knock-on effects on other elements. Luckily though, as a homeowner, you probably won’t need to delve into the details of how gas boilers work on an engineering level! Instead, we’ve put together a list of the most common issues you might come across with your boiler along with advice on how to fix them.

Loud knocking/clanging sounds

One of the most common issues with gas boilers is excessive noise. If your boiler starts making loud clanging noises, it could be a sign that the thermostat has failed. If the thermostat has failed, it will prevent the boiler from heating up correctly. This can cause your boiler to overheat and it might also cause the pressure inside the system to increase to dangerously high levels. Unfortunately, once the thermostat has broken, there isn’t a lot you can do to fix it. However, there are a few things you can try to reduce the noise caused by the thermostat failing. You could try turning the thermostat down, moving the boiler to a different part of the house or covering it with a blanket.

Unusual smells

One of the first things that people notice when there is a problem with their boiler is an unusual smell. This can come from a few different places in the system. Most boilers have a flue that connects to the chimney. This flue allows the boiler to expel harmful gases through the chimney and outside of the home. If there’s a blockage in the flue, it might cause a gas smell to come back inside the house. If you smell gas inside the house and you don’t have a flue installed, you should call a professional to come and inspect the boiler. You could have a leak in the system that might cause an explosion if it isn’t dealt with immediately and it’s always better to be safe than sorry! In addition to the flue, gases are also released from the boiler during the combustion process. Combustion is the chemical reaction that takes place when fuel such as gas is burned. If there is a blockage in the boiler’s burner, it could cause a buildup of pressure inside the boiler and lead to a gas smell. You should have the boiler inspected as soon as possible if you notice a gas smell.

Boiler won’t turn on or is constantly turning off

If your boiler won’t turn on or keeps turning off, it could be a sign that the pump is failing. The pump is responsible for circulating water through the system; without it, the boiler won’t be able to heat the water up, which is one of its main functions. If the pump is broken, you will need to get the boiler repaired straight away. If you don’t, you might experience a loss of hot water and you also run the risk of causing more serious damage to the boiler. If you have been experiencing issues with the boiler turning off and you know that it isn’t related to the pump, it could be a sign of a problem with the pressure relief valve.

Heating isn’t working as it should

If your heating isn’t working as it should, there could be a few different reasons for this. Depending on the age of your boiler, it might be due to a broken thermostat or pressure relief valve. If you’re having issues with the thermostat, you can check the settings and see if they need adjusting. If that doesn’t work, you might need to replace the thermostat, especially if it is beyond its lifespan. If you have an older boiler with a pressure relief valve, it is a sign that the valve has failed. Depending on how old your boiler is, you might be able to buy a replacement pressure relief valve and install it yourself. If the boiler is older, you will need to get the boiler repaired or replaced.
