Your Boiler - How Long Will It Last?

Investing in a new boiler can come with a high cost but often, many people ask how long does a boiler last?

The answer to this question is not that simple as it can be determined by a number of things. There are many manufacturers and they all offer different warranties and while the systems they offer can differ considerably.

What You Need to Know About Boiler Warranties

The majority of boiler manufacturers will offer warranties of around five years but some will offer warranties that are longer as some can offer as much as 12 years while others offer 10 years. One thing that many people might not realise when it comes to boiler warranties is that many manufacturers will offer an extended warranty on top of their existing warranty. Therefore, you can extend your warranty length to ensure that it remains protected for longer. What this means is that you might want to consider this when it comes to budgeting for your new boiler.

A warranty might give you an idea of how long a boiler is likely to last without suffering from problems, the warranty alone is not the only factor that is involved in the life expectancy. One of the most important things about the lifespan of a boiler is how it is looked after and serviced. This can significantly impact the health of your boiler and how long it lasts.

If you want to make sure that your boiler remains healthy, then it is important that you have an annual service. If your boiler is well maintained then it will work well for many years. A  new boiler that is never serviced is more likely to suffer from problems a lot sooner than you would expect and this can also cause your warranty to become invalid, which could cause even more problems for you, including increased costs. So, what this means is that a boiler with a long warranty doesn’t necessarily mean that it is the right boiler for you.

How to Prolong The Life of Your Boiler

Regardless of whether you have a combi boiler or a system boiler, there are a number of things that you can do to make your boiler last longer. 

An annual service will be one of the most important things that you can do to keep your boiler healthy. However, you should also focus on ensuring you take care of your radiators. From power flushing to bleeding them, you can clean the system and reduce the stress on your boiler, ensuring it doesn’t work too hard.

You can also install a magnetic filter as this will help to avoid the problem of too much sludge that is located in your system and the pipework. Furthermore, you can also add inhibitor which will reduce scale in the system, which is particularly important for those areas that are prone to limescale. This might differ for many but limescale can be a real issue for some people.

You should also aim to run  your boiler on a regular basis, especially during the summer months. This might sound strange but your boiler can actually suffer from not being used. Therefore, run it regularly to ensure that it functions correctly.

If you have any external pipework such as a condensate pipe then that could suffer from frost during the winter months so you should lag pipework. This is a common problem but many plumbers and heating engineers find that frozen pipes become a regular issue for them to deal with. Some simple preventative maintenance can really make a difference.

When is it Time to Replace My Boiler?

If you have a boiler that is more than ten years old then you should start thinking about replacing it. An older boiler becomes less efficient and that can lead to higher running costs. With the latest boilers, you will find that they are more efficient and that means that you will save money on your bills. 

One of the things to think about when having a new boiler is that the installation costs can change quickly if you need to change certain elements of your central heating system. You should make sure that you consider this when working out the cost of a new boiler. The reason for the increase in cost is that your qualified heating engineer will need to undertake more work to ensure that your installation is completed correctly.
