Repipe rad to loop?

FizzFizz Posts: 230Member
Thinking of repiping 2nd floor Richardson rad to loop on separate run.  Rad doesn't heat unless valve to add-on 2nd rad(not a Richardson) attached to lat B is completely turned-off.  The system is 2 pipe.  Apparently supply pipe doesn't support attached edr.  Good idea?  Hope attached primitive drawing helps.

    I believe

    I believe your A pipe would have to be 2" for this to work.

    Sorry

    Should have also mentioned that the risers to each radiator should be 1" instead of 3/4".
