repiping

Be careful with loop piping with large cast iron rads. You have to size for the BTU dump at each rad and the piping gets large to carry the whole load. I always prefer a monoflow system. Depending on the piping arrangement, you may be able to install a small circ on each runout, but this can get costly. Consult a good heating pro to evaluate the system and make suggestions.
