How long does a combi boiler last?

Is it time to replace your boiler?

This guide will tell you how long you can expect a combi boiler to last and the signs to look out for that could indicate it’s time for a new one.

A new boiler is a large expense, but once your existing model reaches the end of its lifespan it’s usually more cost-effective to invest in a new one rather than continue to pay for repairs – more so because the parts for old boilers can be hard to source and are often expensive.

So, how long should you expect your combi boiler to last?

You can expect most modern combi boilers to last at least 15 years. However, there are several factors that could alter your boiler’s life expectancy.

These include:

The brand and model you have: Generally, if you spend a bit more and get a high-quality boiler from a trusted brand, then you can expect it to last longer.

Whether you’ve had your boiler serviced regularly: Having your boiler serviced by a professional regularly can help to extend its lifespan. During a service, the engineer will check everything is in good working order and clean, repair or replace any components that need attention. This will keep your boiler working efficiently for longer and help to avoid a hefty bill for repairs.

Your annual usage: As with most things, the more you use your boiler, then the shorter its lifespan is likely to be.

Signs your boiler has reached the end of its lifespan

While you want to get as much usage as possible out of your combi boiler, it’s important to recognise when it is more cost-effective to stop paying for repairs and invest in a new one.

Here are five signs that could indicate your existing boiler has reached the end of its lifespan:

  • It’s more than 15 years old
  • It’s not energy-efficient and your bills are high
  • It’s needed a lot of repairs in recent years
  • It’s becoming difficult to source the parts to repair it
  • You’ve extended your home and your existing boiler is no longer suitable
  • It requires a very expensive repair to get it up and running again
  • It’s become very noisy

If you extend your home, or make significant changes to its layout, then you may find your existing boiler becomes overworked and inefficient.

Some people also choose to update their old boiler when they see the features available with new combi boilers featuring smart technology.

Updating to a smart boiler can be more convenient, creating a warmer, more comfortable home, while also reducing your energy bills and carbon footprint.

When buying a new boiler, always shop around for models that have a long warranty. Generally, the longer the warranty, the better quality the boiler is.
