More radiator problems

[nhopkin]

First off apologies for posting a question I know id already answered on the forums, but I've had a look and most of it means nothing to me, I have all but the basic (if that) understanding of central heating etc.

We had to take two radiators off the wall to decorate, now that we've put them back on they're not getting hot. They were getting slightly warm at the bottom, so bled them and know they're not getting hot at all, the pipes leading to the radiators in question are also cold. The radiators we've not touched are still hot.

Any help please!?

Many thanks

You will need to balance your other rads, go around to your other radiators which are nice and hot and shut the lockshield right down then open up just a couple of turns, do this on all your other rads and see if your 2 cold rads start to get hot.

Thanks Dan much appreciated, didn't seem to work though, one of the pipes leading to one of the rads did get a bit warm, but not for long though.

If there are thermostatic valves on the radiators and they've been turned OFF for a considerable time they could be stuck.
