How to stop radiator clicking

Harrison Clayton March 30, 2023 12

Is your radiator making annoying clicking sounds? Don’t worry, you are not alone. Many people experience this issue, especially during the winter months when the heating is in use more frequently. The clicking sound can be quite bothersome, disturbing your peace and even affecting your sleep. But fear not, there are several simple and effective solutions to this problem.

1. Bleed the Radiator: One of the most common causes of clicking noises in radiators is trapped air. Air can become trapped inside the system, causing the water flow to be disrupted and resulting in clicking sounds. To resolve this issue, you can try bleeding the radiator. This involves releasing the trapped air by using a radiator key to open the air vent, allowing the air to escape. This simple procedure can often solve the clicking problem.

2. Adjust the Valve settings: Another common cause of radiator clicking is incorrect valve settings. It’s important to ensure that the thermostatic radiator valve (TRV) and lockshield valve are correctly adjusted. The TRV should be set to an appropriate temperature, while the lockshield valve should be open just enough to allow proper water flow without causing clicking noises. Adjusting these settings can often help eliminate the clicking sound.

3. Use Acoustic Pads: If bleeding the radiator and adjusting the valve settings do not resolve the clicking issue, you may want to consider using acoustic pads. These pads are designed to absorb sound vibrations and dampen the noise produced by the radiator. They can be easily attached to the back of the radiator and are a great solution for reducing or even completely eliminating the clicking noises.

By following these simple and effective solutions, you can say goodbye to those annoying radiator clicking sounds. Enjoy a peaceful and quiet living space, free from the disturbances caused by a noisy radiator!

Reasons for radiator clicking

There are several possible reasons for a radiator to make clicking noises. Understanding these reasons can help in troubleshooting the issue and finding a solution. Here are some common causes of radiator clicking:

Expansion and contraction of metal

As the water inside a radiator heats up and cools down, the metal components expand and contract. This can result in clicking or ticking noises as the metal moves slightly. It is more common in older radiators or ones that have been in use for a long time.

Loose pipes or fixtures

If the radiator’s pipes or fixtures are loose, they can rattle or vibrate when the heating system is turned on or off. This can generate clicking sounds. Inspecting and tightening any loose components can help eliminate this cause.

Air trapped in the system

When air is trapped in a heating system, it can cause bubbling or clicking noises as the air moves through the radiators. Bleeding the radiators or purging air from the system can help alleviate this problem.

If the clicking noise persists or is accompanied by other issues such as leaks, reduced heat output, or frequent system malfunctions, it is recommended to seek professional help from a qualified heating engineer. They can diagnose the specific problem and provide appropriate solutions.

Tips to fix radiator clicking

If your radiator is making a clicking noise, it can be quite annoying. Fortunately, there are several things you can do to fix this issue. Here are some tips:

Bleed the radiator: The clicking noise may be due to air trapped inside the system. By bleeding the radiator, you can release the trapped air and eliminate the clicking sound.
Tighten the valves: Check if the valves on the radiator are tight. If they are loose, use a wrench to tighten them. Loose valves can cause the radiator to click.
Check for leaks: Inspect the radiator for any signs of leaks. Leaks can affect the pressure in the system and may cause clicking noises. If you find a leak, fix it immediately.
Replace worn-out valves: Over time, valves can wear out and become faulty. If this is the case, it is recommended to replace them. Faulty valves can create clicking sounds.
Clean the radiator: Dust and debris can accumulate inside the radiator, causing it to make clicking noises. Regularly cleaning the radiator can help prevent this issue.
Seek professional help: If none of the above tips work, it is advisable to consult a professional plumber or heating engineer. They will be able to diagnose the problem accurately and provide a specific solution.

Remember, addressing the clicking noise in your radiator as soon as possible can prevent further damage and ensure the proper functioning of your heating system.

Consult a professional plumber

If all else fails, or if you are uncomfortable attempting to fix the radiator clicking yourself, it is always best to consult a professional plumber. A plumber will have the necessary knowledge and expertise to identify and resolve the issue with your radiator.

When consulting a professional plumber, it is important to communicate your specific problem with them. Describe the clicking sounds you are hearing and any other symptoms or issues you have noticed. This will help the plumber understand the problem and come prepared with the appropriate tools and equipment.

Additionally, a professional plumber may be able to offer further advice on how to prevent the clicking from happening again in the future. They can inspect your entire heating system and address any potential underlying issues that may be contributing to the problem.

Remember, attempting to fix radiator clicking issues on your own without the necessary knowledge and experience can lead to further damage or may even be dangerous. It is always best to leave it to the professionals and consult a licensed plumber for help.

Regular radiator maintenance

Regular maintenance is essential to keep your radiator functioning properly and prevent any clicking noises. By following these simple steps, you can keep your radiator in good condition.

1. Bleeding the radiators

Over time, air can accumulate in the radiator system, causing issues such as clicking noises. Bleeding the radiators is the process of removing trapped air. To do this:

Ensure that your central heating system is turned off.
Use a radiator key or a screwdriver to slowly open the bleed valve at the top of each radiator. Air will start to release.
Keep the valve open until water starts to flow consistently without any air bubbles.
Repeat this process for each radiator in your system.
Once all the radiators have been bled, make sure to check the pressure in your boiler and top up if necessary.

2. Cleaning the radiators

Dust and debris can build up on the surface and inside of your radiators and affect their performance. Cleaning them regularly can help prevent any clicking sounds. Follow these steps:

Turn off your central heating system and let the radiators cool down.
Use a vacuum cleaner or a soft brush to carefully remove any loose dust or debris from the surface of the radiators.
If the fins are accessible, gently brush or vacuum in between them to remove any accumulated dirt.
For more thorough cleaning, you can use a mixture of warm water and mild detergent. Soak a cloth in the solution and wipe down the surface of the radiator.
Allow the radiators to dry completely before turning the heating system back on.

3. Checking for leaks

Leaks in the radiator system can contribute to clicking noises. Regularly inspecting your radiators for any signs of water leaks can help prevent further issues. Follow these steps to check for leaks:

Look for signs of moisture or water puddles around the base of the radiators.
If you notice any leaks, tighten the valve connections using a wrench or seek the assistance of a professional plumber.
If you are unable to fix the leak or suspect a more significant issue, it is advised to call a professional to investigate and repair the problem.

By performing regular maintenance and addressing any issues promptly, you can keep your radiator running smoothly and eliminate clicking noises.

Replacing faulty radiator parts

If you have tried all the troubleshooting steps recommended but your radiator is still clicking, it may be necessary to replace some faulty parts. Here are some common radiator parts that may need replacing:

Valve

One possible cause of clicking noises in radiators is a faulty valve. The valve controls the flow of hot water into the radiator and, if it is not functioning properly, it can lead to issues like clicking sounds. To replace the valve, follow these steps:

Turn off the heating system and allow the radiator to cool down completely.
If your radiator has a lockshield valve and a thermostatic valve, make sure to close both valves.
Detach the old valve from the radiator by unscrewing it.
Attach the new valve to the radiator, making sure it is securely fastened.
Open the lockshield valve slightly and then open the thermostatic valve.
Turn on the heating system again and check if the clicking noise persists.

Pipe

Another potential culprit for clicking noises could be a faulty pipe. If the clicking noise seems to be coming from the pipe rather than the radiator itself, you may need to replace the affected pipe. Here is a general guide on how to replace a pipe:

Turn off the heating system and allow the radiator and pipes to cool down.
Locate the section of the pipe that needs to be replaced.
Use a pipe cutter or saw to cut out the affected section of the pipe.
Measure and cut a new piece of pipe to the required length.
Connect the new pipe to the existing pipes using connectors and couplings.
Make sure all connections are secure and tight.
Turn on the heating system again and check if the clicking noise is gone.

If you are unsure about how to replace these parts yourself, it is recommended to seek the assistance of a professional plumber or heating engineer. They will have the necessary tools and expertise to properly diagnose and fix the issue. Remember to always prioritize your safety and follow any manufacturer instructions specific to your radiator.
