How long do combi boilers last?

Generally speaking, you can expect modern combi boilers to last for around 15 years, or potentially even longer if you get a good quality model and service it regularly. Although, they will become less efficient as time goes on, so you will need to keep an eye out for any common boiler faults 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.

Do combi boilers need servicing?

If your combi boiler is over 10 years old, you might be wondering whether it’s worth servicing or repairing or just opting for a new one.

There are a range of issues that could require you to book a service. These include:

However, if these problems continue to affect you, and your boiler isn’t working, it’s probably time to consider a new boiler.

While buying one outright represents a significant investment, there are a range of payment plans available that make them more affordable.

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 will contain the year that the unit was manufactured.

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

While there might be obvious indications why it may be time for you and your ageing boiler to part ways, there are reasons why opting for a new model may be a wise move anyway.

  1. 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.

  1. 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.

  1. 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.

  1. 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 type of boiler should you choose?

While combi boilers are most people’s choice when it comes to choosing a highly efficient boiler, as well as one that won’t take up too much space, there are different types of central heating system that you may want to consider.

Combi Boilers

A combi boiler (or combination boiler) is the most common boiler type in the UK, as it provides both hot water and heating for your home and is highly cost-effective to operate. It also doesn’t require cold water storage or a hot water cylinder and is easy to fit into small to medium-sized homes.

There are a wide range of boiler brands and models to choose from, ranging from boilers that are perfect for larger properties to those more suitable for small flats.  All are complete with a manufacturer warranty up to 10 years, which when combined with a service plan, can help provide peace of mind when it comes to your central heating.

System Boilers

A system boiler is similar to a combi but requires an additional hot water storage cylinder. The system boiler will initially heat the mains water, whilst the hot water cylinder will store and maintain it - so you'll never be without hot water. It's ideal for homes with more than one bathroom as it can deliver hot water to multiple taps and they’re also very economical to run.

Regular Boilers

Mostly found in older systems, a regular boiler is similar to a system boiler, but also requires a cold water storage tank (often found in the loft), as well as a hot water cylinder. This type of boiler is ideal for larger homes with more than one bathroom and low water pressure.

How much does a replacement boiler cost?

 Getting a new boiler fitted can cost anywhere between £1,549 and £3,500, which includes the price of the unit itself, the installation and warranty registration.

The type of system you choose will have a significant bearing on this cost. Combi, system and regular boilers all work differently and provide varying levels of power to the central heating system based on the requirement of a particular property.

Each type also requires different parts and fixtures, such as a hot water cylinder for system boilers and both a hot water cylinder and a cold-water storage tank for a regular boiler, all of which will affect the total price.

Our dedicated guide breaks down the cost of a new boiler and what influences the final price.

What you can do to look after your boiler

Until the time comes when you need to replace your boiler, there are things you can do to keep your heating running as efficiently as possible.

  1. Get an annual service

Having an annual service on your boiler is extremely important. Not only does it protect your manufacturer warranty, but a full inspection of your unit by a qualified Gas Safe Engineer can eliminate any problems at their earliest stage.

An annual service is also the most effective way to prevent exposure to carbon monoxide, which can have potentially fatal consequences if left unchecked.

  1. Don’t put off repairs

While it may be tempting to put off boiler repairs and save money in the short term, it will only prove to be a false economy when you suddenly require an emergency call out. If something seems wrong with your heating, it’s best to call an engineer before it develops into something serious.

  1. Set up a care plan

By having adequate boiler cover in place, you’ll be protected should you need any unexpected and costly repairs. At Boiler Plan, our care plans include a basic level service package, right through to Platinum protection, which covers your entire heating system for ultimate peace of mind.

  1. Use a reliable engineer

It goes without saying that you must use a Gas Safe engineer when it comes to looking after your boiler. This accreditation means that they are legally qualified to work on gas appliances and will be able to ensure that your appliance is running safely and efficiently.
