Hello, I have had a look at other posts to see if this has been covered, but I couldn't find it, if it has , Sorry.

My problem is, all the radiators up stairs only heat up across the bottom, about 20mm high. They are all pretty old, and are single radiators. does anyone know what the problem could be and how do I fix it?? Thanks in advance for your help.
Kind regards

thanks for your advice, I have not bleed them yet, I have never done this before (this is my 1st house with central heating) I take it this is a pretty easy job. The problem started when we had our new kitchen extention, and a nwe rad was put in, could this have highlighted the problem?

Thanks for your help thus far, but I bleed all my rads and still nothing.
I turned the central heating off, opened the valve, air came out, but no water? (the downstairs ones water came out as I expected) I left it for a few minutes, could it be there is just not enough water in my system? is it easy enough to top up?? sorry if these sound like dumb questions, but I am a real newbie with plumbing!!

I have a newish combi boiler fitted, if this makes any difference?

Also, I have sheared off one of the valve screws, are these pretty easy to get hold of??

Thanks Simon

Thanks, it was at the botton, I found the instruction manual and got it sorted, as soon as it started to fill up with water, the bar pressure reading went up, so all sorted! thanks for your help..
