It can be difficult to know exactly how old your boiler is, especially if you are moving into an older home. It’s frustrating when your boiler breaks down, but replacing an old boiler before it breaks down beyond repair is a smart idea, as you can plan for it financially and you won’t be left without heating or hot water.
We have put together this guide to help you understand the warning signs that your boiler may need replacing.

Reason 1: Reached its technical lifespan
The technical lifespan of a boiler can be up to 25 years, but what does it mean? As your boiler ages, the technical parts will begin to deteriorate meaning:
- You will spend more money on repairs.
- The mechanical systems will wear over time.
- The boiler will become less safe.
- Your overall boiler maintenance costs will increase once it has reached its technical lifespan.
Reason 2: Reached its economic lifespan
The economical lifespan of a boiler is the time period in which it continues to work, but no longer runs efficiently. Your boiler will run efficiently for around 15 years, as long as it is well maintained and serviced regularly.
Although your boiler may work for many years after this, it will run less efficiently, so your energy bills will be higher.
Reason 3: Regular breakdowns
Boilers break down every now and again, which shouldn’t be a cause for concern. However, if you’re experiencing boiler break downs frequently, for example more than twice a year, it may be time to consider replacing your boiler.
- Calculate the cost of calling out an engineer regularly.
- Consider the cost of parts.
- It may be the best option financially to replace your boiler.
- A new boiler will come with a warranty.
- Your new boiler will be safe and efficient.
Reason 4: Higher energy bills
If you have noticed your energy bills increasing over the last few months, you need to investigate why.
If there have been no dramatic changes to your living situation, it may be due to your boiler. Over time, a boiler’s energy efficiency decreases, resulting in higher energy bills.
A good tip is to check your energy bill for the same time last year and if it is more expensive, it’s likely you’re using more energy to produce the same amount of heat.
Reason 5: Replacement parts are not available or expensive
If you have a boiler that has seen better days, it’s not just energy efficiency that can be a problem. You also need to consider the availability of parts. Getting parts for older boilers can be an issue because:
- The boiler may no longer be in production.
- The parts may no longer be available.
- The parts may be difficult to get hold of, therefore more expensive.
Your radiators do not heat up properly, or heat very slowly
If you turn on your heating, but don’t notice any heat from your radiators for hours, there is an issue with your boiler system. You’re not benefiting from any heat, but you’re still paying for the energy your boiler is using. Some of the problems you could have are:
- Your system may be filled with sludge that is causing a blockage.
- Dirty water and sludge will cause long term problems with your boiler.
- Cold spots on your radiators which indicate your system is not working properly.
Reason 6: The flame has turned yellow
When your boiler is running at its best, there should be a blue flame burning brightly. However, if
the flame is yellow, you need to get your boiler looked at by a professional immediately. This is because there could be a problem with the carbon monoxide that burns in your boiler, which can be a serious issue.
Reason 7: Corrosion
Corrosion can cause huge problems in your boiler. Over time, it will cause your boiler to rust, damage the internal parts, and contaminate the water. If you notice rust or corrosion on your boiler tank, it’s likely you will need to replace it.
Reason 8: Doesn’t support smart controls
Many homes now have smart meters that clearly shows the amount of energy you are using. Smart metres can also link to an app, so you can control your heating from your phone.
Older boilers do not support this new technology. By keeping your older boiler, you’re missing out on smart technology that makes heating your home more efficient and convenient.
Replacing your boiler
If you decide to replace your boiler, it’s important to make sure you choose the right one for your lifestyle. Although there is an initial cost, there are many benefits to installing a new boiler long term.
Choose the right size boiler
You need to choose the right size boiler for your home to ensure it works efficiently, and does not waste energy. A boiler expert will be able to help you choose which size boiler is best for you, but you should consider the following:
- The size of your home.
- The demand for hot water.
- The number of radiators you have.
- The type of boiler that is suitable for your home.
Save more energy by insulating your home and installing and energy efficient glazing
Your boiler is responsible for heating your home and hot water, but you can give it a helping hand by making energy saving choices around your home.
- Choose energy efficient glazing such as double glazing, which will control the temperature of your home effectively.
- uPVC is extremely energy efficient, so using this material for your windows will make a big difference to your energy usage.
- Around 25% of heat can be lost through an uninsulated roof. It’s key to invest in at least 11.5 inches of insulation in your loft, to minimise heat loss.
