another kind of radiator issue

[Jim]

I have one radiator where the inlet pipe can be roasting but the radiator doesnt get hot enough. I find no air in the rad. The exit pipe doesnt seem to get hot at all. I have adjusted the lockshield to half way. To get the rad hotter. Do I close it or open it more please to increase heat ?
Help

i am not a plumber or heating engineer.
It sounds like like radiator is blocked with sludge.

Try taking the radiator off (close both valves) and try flushing the radiator itself.

What type of heating system do you have?

Do you have thermostatic rad valves?

Has the rad ever worked?

If so did it stop working suddenly?

Has any work been carried out on the system recently?

How old is the system?

The system is probably old as it has a Baxi back boiler. I have only just moved in so dont know how long the problem has existed. There are no thermostatic valves. The heating and hot water system works fine everywhere else but this one radiator. No work has been carried out on the system. The rad does heat up but not as much as the others in house.

If the feed valve is definately sound then it sounds like a possible sludge blockage. Try removing the rad taking it outside and give it a good cleaning with a hosepipe.

You could also try introducing a sludge removal compound such as Fernox leave for 24hrs then draining the whole system down and refilling a couple of times..

Thanks a lot for your advice. I will try the idea.
