Don't agree about 3 hours. If the boiler is cycling the rad and pipework will continue to click. Plastic friction reducing spacers on the brackets are designed to deal with this. Cut out some old plastic pot (yoghurt comes to mind) and place it in the slot on in the bracket. May be easier said than done.
Ticking Radiator Problem

its a bomb!
I've replaced the brackets but I've noticed that on two of the radiators there is the ticking sound coming from one of the valves on each of the radiators...
Do these valves need replacing? If so how much hassle is it?
Thanks

Do the pipes to these valves come through a hole in floor? Poss the hole is too small and pipe moves against floorboard during expansion and contraction. May also be pipe rubbing against joist in floor under rad.
Can't be sure, but if it's tight ander floor, maybe rubbing on joist, etc. TRVs don't usually tick.
Get the WD40 out for the brackets at least to diagnose the problem, and if you think its pipes under the floor rubbing against the timber try a liberal dousing of talc!
Hi,
Quick update...
I've had my system powerflushed as the water was black and had a magnaclean filter installed too.
The ticking is still continuing though. I've noticed that if I shut the problem radiator off the ticking does stop (close both valves either side). This seems to indicate that the problem is with the radiator or it's valves and not the piping under the floor unless someone else argues otherwise.
I'll try WD40 on the brackets but I'm worried this will chemically degrade the plastic brackets. Can someone advise further on this?
My next course of action is to freeze the pipe and replace the valve.
Thanks!

Probably wont harm it but if you are concerned then maybe silicone spray or grease would do the job.
If anyone's interested...
Found that the central heating pipes were pressed against the underside of the floorboards. I had to chisel some wood on the joist around the pipes and then plane the underside of the floorboard to give the pipes room.

Ha ha, we had this, it's infuriating isn't it? You've got a small blob of solder that's jumping up and down in the up-current in the flow pipe and can't get into the radiator. Turn the valve down slowly until it stops jumping then send me a £10 beer token for having solved your problem.
