Noisy radiators keeping me awake

My radiators make a loud clucking popping sound in the morning when the central heating system first fires up, this noise lasts about 45min to an hour. It also happens at night. I don’t really notice the noise during the day (only weekends when I am home in the day). What is the cause of the loud noise in the morning and how can I stop it as it wakes me?

Power flushing will only make the plumber richer and the house will still be there ,lag round pipes going over the joists,and clip pipework

Its the expansion where the pipe goes through the timber joists aren't big enough so when the pipe heats up it expands which pushes against it and causes noises or faulty TRV/dirty system.

Sounds like you system is pulling air in and takes a while for it to settle down

Depending on how big the installation is? can noise oscillate in minutes and hours? Air in the heating system and no pipes fitting not adequately clipped

If you fit an automatic bypass it will take the shock load out of the system

Most often caused by pipes moving on expansion in notches in joists. There should be felt around the pipes in notches but this is often ignored by many installers. Can also be caused when the plastic inserts have not been fitted onto the rad brackets. But this is usually only for about 5 minutes as the rad is heating up.

There are many things that can cause this phenomenon all are mentioned above, but best bet is that if the system has not been power flushed it will be most lightly the cause of the problem. Kettling in the boiler can also cause quite a noise through out the system, this is when the pipe work becomes restricted and the flow is reduced.

Pipes expand/contract during heating up and cooling down and if the pipes are rubbing against wood beams or whatever they are resting on it can make noises. If you can get access to pipes and put some lagging material between pipes and what they are touching this may reduce noise.

May need powerflush , pipes not adequately clipped . IS the rad water when you bleed it black ? If yes the system needs a flush and inhibitor installed

You may have a faulty thermostatic valve, which can send a vibration through pipe work.

It's the expansion of the pipes heating up. It will make similar noises when it's cooling down its usual caused be numbers on first fix not notching the pipe hole big enough and has no we're to expand. Plastic pipes don't do it.
