Reasons Why Your Boiler Might Break Down and How to Prevent Them

Boilers are a staple in many homes and businesses across the UK. They provide heat and hot water for our everyday needs, so it’s important to know how to prevent them from breaking down. This blog post will look at some of the most common reasons for boiler breakdowns and what you can do to avoid them. We’ll also touch on some of the dangers of an overheating boiler and what you should do if you find yourself in this situation.

If you want to keep your boiler running smoothly all year round, it’s essential to know it inside out. Keep reading for more information on maintaining your boiler and avoiding costly breakdowns by availing boiler breakdown cover.

Lack of maintenance

A lack of boiler maintenance is one of the most common reasons for a boiler breakdown. 

Your boiler may malfunction if it has to be reset frequently. Carbon monoxide is one of the most deadly gases on earth, known as the “silent killer” for its colourlessness and odourlessness. It can be released into your home by a faulty boiler. Regular maintenance and repairs are needed to keep boilers working safely.

Without regular servicing, boilers can develop faults and eventually break down. To avoid this, a qualified gas safe registered engineer must have your boiler serviced at least once a year. This will help identify potential problems and prevent them from becoming serious issues. 

Unprofessional boiler installation

Another common reason for boiler breakdowns is incorrect installation. If your boiler isn’t installed correctly, it can cause several problems, including leaks, overheating, and pressure issues. This is why it’s important to use a qualified engineer when installing a new boiler.

If you already have a boiler installed, check it regularly for any signs of problems. If you notice any leaks, unusual noises, or changes in performance, contact a qualified engineer as soon as possible. These could be signs of a serious issue that needs to be addressed before it leads to a breakdown.

Boiler Overheating

Overheating is one of the most dangerous problems with a boiler. If your boiler overheats, it can cause severe damage to the system and potentially put you and your family at risk. That’s why it’s essential to know the signs of an overheating boiler.

If you notice any of the following signs, turn off your boiler immediately and call a qualified engineer:

– A strange noise coming from the boiler

– A burning smell

– Steam or smoke coming from the boiler

– The boiler is hot to the touch.

An overheating boiler can be dangerous, so you must take action immediately if you notice any of these signs.


Corrosion is another common issue that can lead to boiler breakdowns. Corrosion occurs when the metal parts of your boiler are exposed to oxygen and moisture, which causes them to break down and deteriorate over time. This can be caused by a number of factors, including poor water quality, high levels of humidity, or even just old age. 

Scale Buildup

Scale buildup is another problem that can occur if your boiler isn’t properly maintained. Scale buildup happens when the water in your boiler becomes too hot, causing minerals in the water to accumulate on the metal surfaces of the boiler. This buildup can insulate the heating elements in your boiler, making it less efficient and more likely to break down. 

Frozen Pipes

Frozen pipes are another potential problem that can occur during cold weather months. If the pipes that supply your boiler with water freeze, it can cause a loss of pressure in the system, which can lead to problems with your boiler’s operation. To prevent this from happening, make sure to keep an eye on the weather forecast and take steps to insulate your pipes if there is a chance they could freeze.

If you follow these tips, you can help prevent your boiler from breaking down. However, even with the best maintenance, boilers can still develop problems. That’s why it’s crucial to have a boiler breakdown cover in place. This will give you peace of mind knowing that if your boiler does break down, you’re covered.

Boilers can be expensive and are an essential purchase for your home. When buying a boiler, you want to get the best deal possible. Have you considered the warranty and how it might help extend the life of your new boiler? Nowadays, boiler manufacturers understand that customers want the most efficient boilers. These businesses are providing more extended warranties for the comfort of their customers. Customers can benefit from longer warranties, especially if the installers are accredited manufacturer installers, as most of our engineers are.
