The worst possible time for a boiler to is in the middle of winter, but it seems this is common around this season. There is a good reason for this. During cold seasons, such systems work harder to provide warm water and keep the structure or establishment at comfortable temperatures. If you did not address the issues that have been developing throughout the year, it might lead to a system failure. The boilers have to go through during winter due to the extra stress, which may lead to malfunction.

Regardless of when boiler issues happen, they’re annoying and costly. As such, knowing how to fix them ensures that you can get your heating system back up and running to keep your company productive.

With that said, here are some common boiler problems and how to fix them:

1. Noise

Boilers will make some form of noise one way or the other. However, any sounds out of the ordinary can mean that the boiler might be facing a problem. Fortunately, specific noise can point out the problem for you. For instance, gurgling sounds can mean that there is a blockage in the pumps, or any explosion-type noise can mean trapped gas.

If you do not know how to fix the problem or cannot identify the source of the noise, call a technician for help.

2. Leaks

Leaks are another common problem with boilers. Unfortunately, leaks can occur almost in any part of the boiler. Wear and tear can cause minute fractures that lead to holes from which water can seep. It can be anything from the pipes to the pressure valves. To fix such problems, you will need a boiler technician to identify the cause of the leak and fix the problem for you. Fixing it on your own may leave the system vulnerable to problems almost immediately.

3. Cold radiators

Sometimes, you may run into a boiler with radiators that are either struggling to heat up or not at all. There can be many causes for this, such as a pilot light not lighting up. However, more often than not, there is air inside the radiators. To fix this problem, you may need to bleed the radiators. In some cases, the problem might be more complicated and require balancing. Call up a technician to do the job for you. They will clean out the radiator to ensure it can properly heat up.

4. Frozen pipes

During winter times, frozen pipes are a common issue. These generally occur because the pipes were not insulated enough, causing the water inside to freeze up. This can lead to burst pipes and other damage. A quick fix to this problem is to run warm water over the pipe to get rid of the frost or wrap it in a warm towel. After that, you can wrap the pipe in some form of insulation to reduce the risk of freezing in the future.


Problems such as these can be a nuisance, especially if you need hot water right away. If you run into any problems, the best solution we can give you is to call up a boiler technician to check on the issue for you. They have extensive knowledge of such systems and will be able to identify the problem. They can also get your system back up and running to keep your business provided with plenty of heat.
