You could try altering the way the radiators are fed. Rads usually
seem to be connected across the bottom with internal conection used to
spread the heat within the radiator. AIUI if you feed in at the top
and out at the bottom (diagonal opposite) you will get a lower return
temperature for the same heat output (but lower flow rate).

It won't make any difference. When bottom fed, the hot rises to
the top in the first couple of channels, and then it's like a top
fed radiator. It's important the return is from the bottom, but
the flow can be either.
