Your boiler is one of the essential pieces of equipment in your home. It keeps you warm and cozy all winter long! But, like any other machinery, it can sometimes break down.
There are two types of boilers, combi boilers, and system boilers. Combi boilers provide hot water on demand, while system boilers store it for later use.

If you are experiencing problems with your boiler, don’t worry – we’re here to help! This page will discuss five common boiler problems and how to solve them.
1) Leaking and Dripping
Leaking and dripping from your boiler is one of the common problems you may encounter. The most likely causes are a faulty pressure relief valve, corroded pipes, or a leak in the heat exchanger. To fix it, you should make sure all screws and fittings are tight and not causing any leaks. If the problem persists, you may need to replace the pressure relief valve or heat exchanger.
The pressure relief valve is the most common cause of leaking and dripping. This valve prevents the water pressure in your boiler from getting too high, but if it becomes faulty, it can allow water to leak from the system. If this is happening, you should replace the valve immediately.
The heat exchanger can also be prone to leakage if it has become corroded over time. If this is the case, you should replace the heat exchanger with a new one.
2) No Heat or Hot Water
If you’re not getting any heat from your boiler, there’s likely an issue with your thermostat settings or malfunctioning parts. You should ensure the thermostat is set correctly and the power switch is turned on. If these settings seem correct, you may need to call a professional to look at the boiler parts for any malfunctioning parts. If you last had your boiler serviced some time ago, it could also be due to a build-up of sludge and dirt preventing hot water from circulating properly.
3) Gurgling Sounds and Noises
Gurgling sounds or noises coming from the boiler can indicate a build-up of air, which may be due to blockages in the burner or flue. It is essential to call a professional to identify and fix these issues, as they could potentially cause carbon monoxide leaks. Additionally, check that the air pressure is set correctly. If it’s too high, this can also cause gurgling sounds.
4) Radiator Leaks
Another common boiler problem is when your radiators start leaking. This could be due to a few things, such as corrosion or loss of connections. You may also see some sediment and debris coming out of the water. If this happens, it’s essential to get it seen immediately, as it could cause long-term damage to your boiler. To fix the issue, you’ll need to replace the corroded parts with new ones and then check all the connections to ensure they are secure.
5) The Pilot Light Going Out
If the pilot light in your boiler goes out, your boiler will stop working. This could be due to different issues, such as a power outage or a blocked flue. To fix this, you’ll need to relight the pilot light and check all connections to ensure they are secure.
