I have had a few problems with my heating lately and have just got my central heating working and 3 of my rads are nice and hot but the 2 on the other side of the flat are cold... i have bled them but still they stay cold.. any help would be great

the rads have trvs
the pipes to the rads are cold but the pipes in the loft that go to the rads are hot but it seems its just not geting there and the 2 pipes in the loft come down the wall and feed both rads if that helps

check the trv's open and not on a low number.
check the pin in the centre of the valve is moving freely.
close the hot rads.
if the systems been balanced count the number of turns you shut each valve.

then the full flow will go to the cold rads, then you can re-open the other rads
 
so by closing off the other rads it should force the hot water around and do i close both the trv and the lockshield
 
hopefully its just an airlock in the drop down pipework.
if all the cold rads come off the same dropdowns.

just close the hot trv's right down.
