Do I need to replace my radiators when I get a new boiler?

The good news is that replacing your boiler doesn’t necessarily mean you have to replace your radiators, however, there are some reasons why you might want to consider it.

Do old radiators work with new boilers?

If you are replacing your boiler with a new one that is the same size, then yes! If the old radiators are in good condition and still working efficiently in your system now, they will most likely work well in the new system as well.

But if your radiators are older, it could affect the efficiency of your new boiler heating your home, corrosion caused by age and frequent usage could cause your boiler to need to work much harder. When your new boiler is installed the engineer will likely perform a flush of your central heating system, which will help, but sludge and corrosion will of course build up much quicker in older rads which can cause poor heat production.

What can I do to prolong the life of my existing radiators?

When installing your new boiler, as mentioned above our engineers can offer a full chemical flush of your heating system. Our MagnaClean chemical cleaner is specially designed to remove sludge, debris and scale which may have built up inside your system over time. We will then fit a MagnaClean, high-efficiency, full-flow filter to prevent the build-up of these unwanted clogs to ensure optimum boiler efficiency and performance. It is important to keep your pipework clean as this is a major cause of boiler breakdown.

How Often Should Radiators be Replaced?

Like anything in your home, radiators can wear out and become less efficient over time. You may find they are not heating your home as quickly, getting blocked up or even becoming noisy. It can become clear that a radiator needs replacing when you find that heat is no longer distributed evenly over its surface, also known as cold spots. It is generally recommended that radiators are replaced every 15-20 years.

Do I need new radiators when replacing my boiler?

As previously explained, it isn’t always necessary, but sometimes it might be a good idea.

Your existing radiators will probably not have been designed as part of an energy-efficient heating system and therefore could be quite inefficient compared to modern models. In recent years there has been plenty of design innovations, and manufacturing quality has improved to comply with higher standards and safety regulations, along with a larger focus on energy saving and reducing water usage – newer models can be as much as twice as efficient as older ones.

Another advantage of replacing your radiators at the same time as your boiler is that it can minimise disruption. Getting installation done together at the same time means you won’t have the upheaval of calling in an engineer a few years later if your radiators begin to fail further down the line.

It might also be an opportunity to modernise your heating system, long gone are the chunky unattractive radiators of old, now there are plenty of modern shapes and colours available to complement the décor of any home.
