How long does a boiler last?

Your boiler is the heart of your home. It helps keep life running smoothly and has a huge impact on your comfort levels. Due to its importance, it’s key that your boiler is kept in the best possible condition to meet your household needs. Part of looking after your boiler includes knowing how long it is likely to function and being able to recognise when it’s time for a replacement.

How long does the average boiler last?

The average boiler should last between 10-15 years before it needs replacing. This is good news for people who have recently invested in a new boiler or those who have moved into a newly built home, but what if your boiler is old and outdated? Here’s how you can keep your boiler in top condition for as long as possible, and how to recognise when it’s time to replace it.

Get an annual service for your boiler

One of the best things you can do to keep your boiler working as efficiently as possible, and for as long as possible, is to get it professionally serviced every year. You need to get this carried out by a Gas Safe registered heating engineer who will perform safety and efficiency tests on the boiler to ensure it is working effectively.

The engineer will also check your boiler for faults or leaks which is a great way to catch small problems early on before they cause expensive breakdowns. It’s also worth noting that annual services by Gas Safe engineers are usually required to ensure your manufacturer warranty remains valid.

Don’t overwork your boiler

Setting the water pressure too high could also cause wear-and-tear on your boiler and, like a car, the more you use your boiler the shorter its life expectancy will be. A boiler of the right size and good quality should be perfectly able to meet your hot water demands for many years to come without any issues.

Don’t ignore faults with your boiler

You should pay attention to your heating system so any changes or unusual noises can be resolved quickly. If you suspect something is wrong, don’t ignore it or put it off for longer than you have to as small problems can lead to big repair costs if left to worsen over time. Small faults also mean your boiler is not performing at its optimum level which means your household could potentially be less comfortable than it should be.

Signs it’s time to replace your boiler:

  1. Your boiler is 10 or more years old
  2. You call the heating engineer out too often
  3. Your boiler is giving off a strange/unfamiliar smell
  4. Your radiators take too long to heat up
  5. You’re cold in your home, even when the heating is on
  6. The blue flame changes to yellow
  7. The boiler is making different noises
  8. Your water temperature is inconsistent
  9. There is a puddle on the floor
  10. Your pipes freeze when the temperature drops
  11. Your energy bills are increasing without an obvious reason

A new boiler could mean cheaper energy bills

As a boiler ages, it becomes less efficient at heating your home as it needs to work harder and use more energy to produce hot water. By replacing an old boiler with a modern, highly efficient model, you could see a significant reduction in your annual energy bills.
