brand new rad...bottom third only warm not hot

[worcesterman47]

hi, just had 2 brand new rads fitted...they both have brand new individual control valves fitted...but the rad in the living room the top & middle get as hot as we want it...but the bottom third of rad just gets just slightly over warm...i have tried turning heating off & bleeding all rads...and also tried giving it a bit of a hit..but it still stays just warm..any ideas or advice would be greatly appreciated

balance it in with the rest of the system.

Why have you had 2 new rads fitted? The old ones corroded and leaked?

If so it could be sludge in your system that has happened to move into the new rad front panel.

Also a real outside shot is that the said rad is faulty. I have had a few that have been manufactured wrong and didn't allow flow through the entire rad.

hi again...firstly i was saying " how do i do that " to reply about balancing the system...secondly, the two rads that were replaced were rusting..but i think only from where i used to bleed them & not wipe off excess water that had run down the edges ( no signs of rust anywhere else just edges under bleed valves)..the guys who fitted the rads after draining system ( approx 3weeks ago) also added something to header tank to dispurse/breakdown any sludge etc( the water from the draining was blackish but not thick or sludgy) ....all the other rads in the house seem to work great...its just the living room one..also i thought the back panel of rad ( as its a double one) was fine but on rechecking it again it seems it the same as the front part...hot at top & middle but just over warm at bottom..also if it is sludge bult up..how do i clear that? or could it possibly be something else..again any advice/help would be greatly appreciated.

Why don't you call the installer back to sort it out? Fitting radiators isn't just a question of hanging them from the wall and connecting the pipes - it's also a matter of making sure that circulation is as it should be.
