What are the signs that my boiler needs replacing?

Boilers are meant to last for many years, but sadly, they do not continue working their best forever. Once your boiler is over 8-10 years old, you might notice that it is no longer working as efficiently as it used to, runs into more problems, and can even become dangerous to your household. This is true even if your boiler does not appear to have any majorly obvious problems.

In recent years, boiler technology has moved on in leaps and bounds and the older models are simply unable to match up to the variety of efficiency levels, smart control options, safety features and more that are available from the boiler market today. 

Here are some of the signs that you boiler needs replacing:


A sure sign that your boiler is due to be replaced is the kettling, gurgling and banging sounds that you might be hearing from your boiler when you run the hot water tap or turn on the central heating

Strange smells

While carbon monoxide does tend to be odourless, some gas companies do add a scent to help it become easier for you to detect if a leak has occurred. An eggy, sulphur-like smell around your boiler is a sure sign that there is a carbon monoxide leak and you should open all the windows and get out of the house as quickly as possible. Contact the Gas Emergency Services as soon as you can.

Yellow flame

A healthy boiler that’s working well should burn with a blue flame. However, if you’ve noticed a yellow flame on your boiler, this could be a sign of a serious issue such as a carbon monoxide problem. This gas is colourless and odourless and often, a yellow flame is the first sign that there’s a problem so it’s important to keep your eye out for it. If exposure levels are high enough, carbon monoxide can lead to serious illness or even be fatal.

Increase in energy bills

A boiler that is getting old and is increasingly less and less efficient can cost more money than most people can afford to spare. And, upgrading to a boiler that includes modern smart controls will not only improve efficiency but also give you a greater control over your energy usage and spending.

Frequent breakdown

Are you noticing that your boiler is breaking down regularly or you are topping up your water pressure every week?

Reduced efficiency

When it comes to energy efficiency, some boilers are just missing the mark due to age. A boiler that’s rated ‘A’ in terms of efficiency will have an energy efficiency level of at least 90%. On the other hand, a boiler that’s rated ‘G’ will have an efficiency level of around 70%, meaning that for every £1 you spend on your energy bill, you’re losing 30p in wasted energy.

Expensive & difficult to find parts

If you’re having increasing problems with your boiler and you have been told by your boiler engineer that new parts are hard to find, it’s a clear sign that your boiler will probably need to be replaced soon. The older a boiler gets, the less likely it is that parts will be readily available. And if you’re struggling to find an engineer who is experienced with the type of boiler that you have, that’s even more reason to consider replacing it.

Boiler Types Explained

Combi boiler

A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.

They are also very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump.

System boiler

System boilers require a cylinder for storing hot water, however the major heating and hot water system components are built into the boiler itself, making it quicker and easier to install. In addition, there is no need for a tank in the loft, so it can be an option in a home with little or no loft space or where the space is earmarked for a conversion.

These boilers are also compatible with solar water heating systems, which deliver environmental benefits as well as lower energy bills.

Regular boiler

Regular boilers (sometimes known as traditional, conventional or heat only boilers) are ideally suited to homes that already have a traditional heating and hot water system which is linked to a separate hot water cylinder. These boilers also need a cold water storage tank in the loft to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.

A regular boiler may be the best option for replacing an existing boiler if the property has an older radiator system, as it might not be able to cope with the higher water pressure that is delivered by system or combi boilers
