If you are buying a new heating system, you may ask: How Long Do Boilers Last? This article looks at the estimated age of a boiler and how to keep it working for longer.

Installing new boilers is expensive, and we try to push this back as long as possible. The question is, how long do our boilers last for?

How long do boilers last?

We rely on our central heating systems and new boilers for warmth and hot water, hoping they last years without a problem arising. If you find yourself asking how long does a boiler last, yet you don't perform annual boiler service, the lifespan will suffer.

Many modern boilers are expected to last between 10-15 years, but this does depend on how often you use it, the maintenance schedule you implement and how it was installed. A boiler installed by a non-professional can experience breakdown more often.

Certain areas of the UK, especially the South-East, suffer from hard water, meaning their central heating systems are affected by limescale more than others. The chemical makeup of your water supply means you will experience more problems as the limescale will create blockages.

You can expect more engineers and servicing than other homes. This being said, noting any unusual changes in your boiler and central heating system can help you improve the lifespan and general health.

 If you are concerned about your old boiler's lifespan and want to improve your energy savings as time passes, there are things you can do to improve the quality and duration of your boiler's life. 

Average Life Of A Gas Boiler

Gas boilers are conventional in many homes, with countless homeowners taking them for granted while fulfilling their heating needs. As long as you're maintaining your gas boiler regularly and have had an inspection by a gas safe engineer in the last 12 months, you shouldn't have to worry about boiler replacements just yet.

If your energy bills have been increasing lately and you are reaching the tail end of that 15-year lifespan, it would be time to consider a new boiler, which means factoring in a replacement boiler cost.

Your boiler warranty will provide more of a breakdown of how regularly you should inspect and maintain the system. Still, conventional boilers should only be serviced by a gas-safe registered engineer.

This to keep the energy efficiency as high as possible while avoiding costly repairs. Sometimes your boiler's efficiency will waver, either because of a busted internal component, thermostat settings incorrectly programmed, or a power flush being required.

Regardless, proper maintenance will help you keep your boiler alive. If you cannot remember the last time you got your boiler serviced, it's time to arrange the next appointment. 

How to Extend the Life of Your Boiler?

Naturally, you want your boiler to continue running efficiently. You rely on this device to provide warm water and heat to your home with a cost-effective plan. After a few years, or potentially significant damage, your boiler becomes inefficient and can start dying, all without you knowing.

You may believe it's cheaper and easier to keep your boiler, but you could be spending more money when components have experienced corrosion due to age.

Let's look at the best ways to extend the life of your boiler.

When should you consider replacing a boiler?

Even when your boiler has survived through its life expectancy of 10-15 years with little-to-no faults, you should start considering a replacement. Old boilers can stop running smoothly over time, with your energy bills increasing as they become less efficient.

Instead of tampering with it yourself, making the manufacturer warranty void, get a qualified engineer in when you notice any of these issues:

Of course, more issues can arise from older models, such as them simply not meeting your requirements anymore. Your life has changed drastically since your last boiler installer, meaning you could want a bigger unit. Your carbon footprint has likely altered too, and getting an environmentally friendly boiler can attract many people.

Before investing in a replacement boiler, you could benefit from a power flush (a powerful chemical flush conducted by a heating professional), clearing out any metallic debris, sludge and air from the system before your new boiler is installed. This can help extend the lifespan of the new unit. However, a system flush can cost you up to £300 in some cases.

How Much Does A Replacement Boiler Cost?

The price of a boiler replacement varies depending on several factors. The most expensive differences come from the boiler type (non-condensing or modern condensing boiler) and the brand (Worcester Bosch or Viessmann boilers). Many heating companies will offer a free quote on their services before you book, but you can expect to pay anywhere between £500-£2500 for a boiler replacement cost.

This cost is so high because of the high standard you're paying for. Gas appliances are dangerous, but with a professional engineer, you receive personalised care. Interestingly, you can pay more for your boiler installer to establish your new boiler in a different location at your home.

You would be wise to get your new combi boiler installed in the same place as the last, saving yourself hundreds of pounds. This price point deters many homeowners from getting a replacement. Instead, they choose to continue with their current model. The cheapest model can still cost you several hundred, especially when you factor in insurance and professional service.

You will be better off ensuring you find a better quality boiler, as it will last you longer and save you money in the long run. While you may pay for this upfront cost, you can experience lower energy bills and less frequent visits from heating engineers.

While your annual services will continue, you can rest assured you have the most efficient boiler possible. If you are suffering from any of the above problems, or your boiler is reaching the end of that 15-year window, you should start saving for a new boiler.

This will save you a lot of money going forward. If your boiler is still giving you problems, contact our team today for support.
