Like most pieces of equipment, boilers are unfortunately likely to break down on some occasions. They are complex machines built from multiple parts, some of which are quite delicate and even the slightest bit of soot buildup can stop them from functioning properly.

Due to the nature of a boilers’ intricate parts, there are several reasons why a boiler could break down. Here, we will give you an overview of the most common reasons for boiler breakdowns, as well as ways you can prevent them from happening.

Older boilers have an increased chance of breaking down due to general wear and tear. The older the boiler gets, the more susceptible it is to rust and corrosion. Over time, boiler parts can start to deteriorate and rust. This deterioration can prevent water flowing through the boiler properly and causing it to break down. To help prevent this kind of breakdown, you should ensure you have your boiler serviced at least once a year. This way your gas engineer can check for any early signs of deterioration and replace and parts as required, before they fail completely.

Mechanical boiler breakdowns are another reason for boilers to stop working. These types of breakdowns aren’t always as a result of goings on within the boiler itself, but external issues. Faulty interconnecting pipework that links your boiler to your radiators and plumbing could have faults in, which can cause the boiler to fail.

It’s important to remember that your boiler is part of a complex, interconnected heating framework and sometimes, if one element of the framework fails, it could affect the entire system. A great way to prevent this from happening is to maintain your radiators properly. Ensure that your radiators are bled regularly to help the trapped air escape. You can also arrange a radiator flushing service to help remove any debris and other deposit buildup within your radiators to allow water to flow through them freely.

Finally, another common boiler breakdown cause is due to a frozen condensate pipe. Obviously, this is only likely during the winter months, however, if there is standing water in your pipes, when the temperature falls below zero degrees, this water will freeze and prevent the boiler from working. Keep an eye on your pipes during the winter months and if you notice your pipes are frozen, gently thaw them out and your boiler should spring back into action.
