Reverse Return

Is there a point where reverse return piping for the radiators on a hot water boiler system really does not make a difference like if you are over piped?

What i mean is if the rads are for 100k btu and you pipe them for 1500k btu. If you use larger than necessary pipes.

I don't understand what you are talking about.

I think I understand, correct me if I'm wrong Ziz...

If the Supply and Return pipes are overSIZEd from the minimum they would need to be for the attached emitters...

With reverse return, the point isn't really about 'flow', it's about 'distance' and 'balancing'.

Reverse return piping allows the total distance from the boiler to any rad and back to the boiler to be equal, thus balancing the flow through each rad.

As long as the flow is proper, there should be no 'issues'.
