When Should You Replace Radiators?

Radiators are an essential part of any home. Despite their resilience, they are subject to general wear and tear and other complications. Most modern radiators last between 10 to 15 years. Although they may last longer, old radiators tend to be less efficient than newer models.

There are a few key signs to look out for to know when you need to replace your radiators. It may feel colder than it should, even after you’ve bled the radiator. This could be a result of issues such as corrosion, which creates a sludge that will block the water from circulating properly. Visible leaks in or around the radiator, strange noises and visible damage are all signs that you may need to purchase a new radiator.

You may have seen an increase in your energy bills, which could be a sign that your radiator needs replacing. Old radiators are less efficient and require more energy to run. Even with a brand-new boiler, its performance will be limited by old radiators. You may find rooms take longer to heat up or don’t reach the temperature you want because of old radiators.

If you’re wondering ‘should I replace 40-year-old radiators?’, the answer is yes. There’s no set time for when you should replace old radiators. However, as a general rule of thumb, you can expect to replace your radiators after 15 to 20 years. Some radiator models may need to be replaced after 10 years if they stop running properly.

What are the Tell-Tale Signs for Replacing a Radiator?

These are a few signs to keep an eye out for as they could indicate you need a new radiator.

Visible damage

Radiators that show visible damage likely need replacing. They could look rusty or corroded, which could result in the formation of holes.

Strange noises

Strange noises, such as clunking or excessive gurgling could also indicate there are problems within the radiator.

Needs bleeding more frequently

You might also find you have to bleed or flush out the radiator more frequently than you used to. This could be a sign that the radiator is corroding inside or isn’t able to circulate the water properly.

How to maintain your radiator to prolong its life

You should regularly dust and clean your radiators to remove any debris. Dirt can obstruct airflow and prevent it heating and cooling properly. You should regularly flush the radiator to remove the build-up of dirt and debris that creates a sludge within the radiator. The sludge can prevent the water circulating properly, which will stop the radiator heating up. Bleeding the radiator will release air pockets within the radiator and ensure the radiator is hot throughout. You should also regularly check the radiator for leaks and lubricate the valves and bolts. Check that the TRV (Thermostatic radiator valves) are functioning properly and replace them if necessary. You may find that the TRV has a stuck valve that is preventing it from maintaining a constant temperature in the room.
