To a point after all the rads returns are commoned? Are you sure?Only a short length of pipe is required to connect to the boiler return once the cylinder is removed.

Bathroom rad is on a summer circuit as was the rad which was removed from that bathroom. All pipework is new.is that bathroom radiator a new addition?
where is the return for that rad teed into ?
What do you mean by a summer circuit? If that rad is fed from the HW valve (in parallel with the HW cylinder) the return should be commoned with the cylinder return, before teeing into the main rads return (at the appropriate place!).Bathroom rad is on a summer circuit
I understood a summer circuit is where the bathroom rad is plumbed to the HW circuit for warm towels in the summer when the CH is off.What do you mean by a summer circuit?
As far as the HW cylinder and bathroom rad are concerned, yes.All that said, your description of how a 'summer circuit' should be plumbed looks to me the way it is actually plumbed ie. the radiator return is connected to the cylinder return, before teeing into the main rads return. That would mean that the original plumber got it correct, yes?
That's correct, but it probably isn't plumbed like that, or you wouldn't have your problem. That's what needs altering. Whether the HW cylinder has to come out to do it I can't tell from here.My belief from what I read is that the cylinder coil outlet should be the last T on the return to the boiler...
