Common Boiler Problems

A sudden issue with your boiler will never happen at a good time. You may be trying to pop the heating on for the first time, ready to hop in the shower or jump in that lovely bath you have been dreaming of all day. However, these things can happen.

Therefore, we would recommend an annual boiler service. A boiler service will check the condition of your boiler and help reduce the risk of it just ‘not working’ one day. However, if you do not have a yearly boiler service you could end up with one of the following common boilers problems.

A Leaking Boiler

A boiler leak will usually be the result of an issue with an internal component, such as a pump seal or pressure valve. A leak could have developed around the pipes in the system and have been caused by corrosion. You will need to call in the services of a professional boiler engineer. They will be able to identify the cause of the issue and fix the issue before more damage is caused.

No Heating or Hot Water

This is one of the most common boiler problems. It is also one of the most annoying because you do not know this is an issue until it is too late. The issue of no hot water or heating could be caused by a faulty motorised valve, broken system diaphragms and airlocks, low pressure in the boiler or even a broken thermostat. We would recommend you check the devices manufacturer guide for a possible solution or call in a heating engineer to find and fix the problem.

Radiator Faults

Cold patches on your radiator and other similar problems are usually caused by a build-up of air or sludge inside your radiators. This can then cause the heat from the boiler to be unequally distributed throughout your home. However, cold patches in different areas of your radiators could be a sign of a different issue. Many radiator issues can be resolved by bleeding the radiators. This is a simple task that can be completed by any home DIYer. However, if you would prefer the help of an expert – call our team of heating engineers.

Boiler and Thermostat Not Working Together

If the clocks have gone back or forward recently, you will need to ensure that your thermostat is in line with the new times. However, if your boiler is completely failing to respond to the times set on your thermostat it could be mean your thermostat controls are broken. If it uses batteries, try replacing the batteries – this is a common fix. However, if the problem persists you may need a boiler engineer to replace your thermostat with a new one.

Gurgling Boiler

All boilers make a sound when they start up and are in operation. However, if your boiler suddenly starts gurgling loudly, banging or you can hear whistling coming from your boiler – this could be a cause for concern. If you hear loud and unusual sounds from your boiler when it is in use, then we recommend you call a qualified boiler engineer to listen to the noise and fix the issue.


Please Note: only perform simple checks on your boiler that have minimal risk. If you are not sure what you are doing do not try and fix the issue yourself as this could be extremely dangerous for you, your home, and your family.
