How long does a boiler last?

Buying a new boiler isn’t the most exciting purchase, but it’s certainly an essential one. With the price tag attached, you’d think they’d last forever. Unfortunately for us homeowners - this isn’t the case.

An expensive investment that is a source of comfort in your home for the whole family. There are many benefits of replacing your current boiler, from improved efficiency to reliability. So when is time to be out with old and in with the new? In this guide, we’ll be explaining how and why boilers can live for so long and when it's time to start thinking about an upgrade.


The lifespan of an average boiler. 

Maybe you’ve had your boiler for 20+ years and haven’t had a single problem with it. In which case your boiler is a veteran and should be given a medal of honour for its services to your home. However, for most regular boilers the average lifespan is around 15 years (the cowards). 

In those 15 years, technology drastically advances - especially in the world of boilers. What was once a white, industrial looking box stuck on a wall now looks something out of an Apple store. Not only visually but mechanically they’ve improved, too. Quieter, compact, and more efficient than ever, modern boilers save you money. Why? Because they require less energy to heat up your home which means lower energy bills every month. Not bad. 

The advice we tend to give people is, ‘don’t leave it too late’ - especially during winter. At around 15 years old, that’s when bigger problems start occurring, such as pipework corroding or gathering limescale. Your boiler might be working perfectly today, but tomorrow it may be a different story. Let’s face it, life without a boiler is no fun. A couple of days without hot water and heating can be a bit of a nightmare. But BOXT is here to save you.

Service your boiler.

Getting your boiler serviced every year is vital and is one reason why some boilers can last for numerous years. Think of it as an MOT but for your boiler. During an annual service, the engineer double checks everything is working properly, providing visual inspections of the boiler and gas appliances. If there’s anything wrong with your boiler, they’ll know. Be sure to get your boiler serviced, that way you’ll know for sure whether your boiler is on its last legs or not.

Pipework corrosion. 

Similarly to the engine of a car, a boiler has hundreds of components all working together to produce hot water and heating safely and efficiently. A boiler that’s 15 years old may appear as if it’s working properly, but underneath the surface there may be other problems. Unfortunately, as boilers become older the risk of pipework corrosion increases. This is something you really do not want. Corroded pipework can lead to water leaks and contaminate your water supply - it can become quite dangerous. 

You’ll know when you have corroded pipework as it has quite an unusual smell. If you’re concerned your pipework is corroded, then contact a professional as soon as possible to confirm. 

Is it time to replace my boiler?

This depends on a couple of factors. The age of your boiler will influence whether it’s time to get a new one. Moreover, keeping an eye out for any unusual smells or weird banging noises coming from the pipes - these are clear signs that there is something not quite right with your central heating. The best thing to do is to have a professional to take a look at it or get a service booked in. That way you’ll know for sure. 

If your boiler is condemned - there’s a lot to consider. Such as, what type of boiler do you want? How many kW? Want it moved to a different room? The list goes on. A new boiler is an investment that doesn’t come cheap, which is why you need advice from the people who know what they’re talking about.
