How long do boilers usually last?

Boilers can last up to 15 years before you need to look at getting a new one – which is good news for many. However, the lifespan can vary between 10-15 for different models. As boilers are a huge investment, this guide will get you up to speed on how to extend the life expectancy and what you can do to ensure your home stays toasty warm.

Do different types of boilers last longer?

There are three different types of heating systems:

  • Combi
  • System
  • Regular (typically found in older systems)

While there are distinctions between the three heating units, the average boiler will last anywhere between 10-15 years. Although, they will become less efficient as time goes on, so you will need to keep an eye out for any errors or issues you begin to notice. Look out for the warranty also, as you may benefit from a free replacement if it falls within a certain time period.

Choosing the right one can be confusing – especially if you are not a dab hand at engineering. The right system for you should be efficient and help to save pennies.

Is it worth servicing an old boiler?

If your boiler is reaching its final stages, you might be wondering whether it’s worth servicing or repairing or just opting for a new one. It’s a huge investment if you are considering getting a new boiler, but there are reasons for doing so.

There are also signs of an ageing boiler to look out for:

How do you check for an old boiler?

If you’ve noticed some of the above issues, it’s worth knowing when your boiler was installed. There’s a quick and easy way to do so by looking for the serial number, as this long sequence of number contains the year the unit was manufactured. 

What are the benefits of getting rid of my old boiler?

As mentioned, there are indications that it is time to part ways. But there are reasons for opting for a newer model.

  • Reduced energy bills

You could potentially save a lot of money and make your home more energy-efficient. As a boiler begins to age, it will have to work a lot harder to heat your home and produce hot water, using a lot more energy. For every £100 you spend on gas, you could be wasting a staggering £40 of this just due to inefficiencies from the older unit.

  • Moving your boiler

If you have made any updates to your home or added rooms to your property, it may be that you want to move the boiler to a less noticeable place. Newer heating systems tend to be more compact and, therefore, can be placed within kitchen cupboards etc.

  • Smart controls

As advancements continue, your old boiler may leave you stuck in the dark. There are heating units and thermostats available that allow you to control your heating through your smartphone. They are a great way to save money and track your usage. We’ve even pulled together a guide on smart thermostats, so you understand exactly how they work.

  • Old parts

If you do repair an older model, it might be worth checking if the parts are still available. If they are difficult to source, it could lead to an increased repair bill. In that case, it might be worth looking at the price of a new one.


What you can do to look after your boiler

There are things you can do, in the meantime, to keep your heating unit running as efficiently as possible.

  • Annual service

You might not realise how important an annual boiler service is, but we are here to tell you that it is extremely important. A Gas Safe engineer can do this for you and will perform safety and efficiency tests to make sure it is in working order. This can help to rectify any problems in their early stages.

Servicing is also the most effective way to prevent carbon monoxide poisoning, which has, sadly, increased by 32% since 2014. Carbon monoxide is a poisonous gas that doesn’t have a taste or a smell and, in most cases, people do not know when they are exposed. However, exposure can have potentially fatal consequences. Therefore, you can alleviate any worries by getting your boiler checked regularly.

  • Don’t put off repairs

It can be tempting to put off repairs – especially if you are trying to save for occasions and any unexpected emergencies. In the short term, that might be the best option. But, doing this can see you digging deeper into your pockets if you require an emergency call-out, particularly during peak periods. The issues could even build up, leading to a much larger bill or even replacement.

  • Get the right boiler for your home

A boiler that works perfectly well in a two-bed home is not likely to offer the same level of efficiency in a 5-bed property. If you are unsure of what is the best option, an engineer will be able to help and provide advice on which will suit your house.

  • Use a reliable engineer

It goes without saying that you must use a Gas Safe engineer. This means they are legally qualified to work with gas appliances and will be able to install efficiently. If you don’t do this and the engineer you choose damages your heating system, it could lead to hefty repair bills and even further consequences if it isn’t installed correctly.

As mentioned earlier, keep your eyes and ears peeled for any unusual activities with your boiler. If you notice any noises or that it doesn’t work as it used to before, you may require an engineer to resolve the issue.
