any tips
Is this just one radiator, and is it like this all the time? If so, the
bottom part is blocked with sludge. When this happens, the cold part is
usually triangular - almost full width at the bottom, getting narrower
further up. The only real solution is to remove all the rads, take them
outside, and give them a really good wash out with a hosepipe - taking care
not to spill any indellible sludge on your carpets! Then make sure that
there is plenty of corrosion inhibitor in the system.
On the other hand, if your radiators are warmer at the top than the bottom
during periods for which the room stat has turned the system off - or TRVs
have turned individual radiators off - this is perfectly normal, and is
simply obeying the laws of convection.
