How long should a combi boiler last?

In general, a modern combi boiler should work for at most 10 to 20 years. This number obviously changes depending on the quality of the model, how well it was installed, and how well you take care of and maintain your boiler. If you don’t take good care of your combi boiler, it’s not surprising that it won’t last as long.

In this blog, we’ll answer some of the most common questions about how long a combi boiler will last, such as when it should be replaced, what a combi boiler is, how it works, and how this affects how long it will last. First, though, what is a combi boiler?

What is a combi boiler, exactly?

The most common type of boiler in the UK is the combi boiler, which provides both hot water and central heating from a single unit. Compared to other boiler types and models, they are popular because they are small, work well, and are not too expensive.

The price of installing a boiler depends on the type of boiler, its size, its location, and other things.

How often should you replace a Combi Boiler?

It depends on how old your combi boiler is. If you’re reading this and your combi boiler is already 10 years old, it may be getting close to the end of its useful life (as an older model). Depending on the model you have, an experienced boiler technician will be able to tell you how long your boiler will last.

If, on the other hand, you are reading this because you want to buy a new combi boiler, the ones on the market today will usually last at least 15 years. But if you take good care of it, there’s no reason why that number can’t be increased to at least 20 years, if not more.

What factors affect how long a boiler lasts?

There are many things that affect how long a boiler will last, such as its age, how often it needs to be serviced, and how well it was built.

Age

We’ve said it before, but it can’t be said enough: a boiler’s age makes a big difference in how long it will last. Older boilers are less efficient, so they need more energy (or work) to do the same job as newer boilers that are more efficient.

If you have two boilers and one does ten times as much work as the other over a period of five years, for example, you can be sure that the less efficient boiler will break down sooner.

How often it gets serviced

Even the most reliable boiler brands will have cheaper models that won’t last as long as their top-of-the-line options.

These “budget” options, which are often still very expensive, are often made with slightly cheaper materials and may not have the same cutting-edge technology as their more expensive siblings.

Because of this, they might not last as long as the more expensive option from the same maker.

Quality Building

If you own a car and take good care of it, like getting it serviced once a year and making sure it passes its MOT, it will probably last you a long time. Compared to that, it’s not surprising that your car won’t last as long if you park it outside and never get it serviced.

The same is true for your combi boiler. Boiler experts recommend having your boiler serviced every 12 months. This lets the main parts of the boiler be taken out and cleaned, and any small problems can be fixed before they get worse.

How long can a combination boiler last?

Yes! There’s no reason why your boiler shouldn’t last at least 20 years, if not longer, as long as you service it regularly and it’s a fairly new model. Their efficiency makes them more likely to last longer, and if longevity is the most important thing, we’d recommend a combi boiler over a traditional system boiler.
