I'm having a new boiler installed to replace my forced hot air system. Instead of baseboard heaters, I'm planning to use some Veha panel radiators. There will also be a toekick heater in the kitchen.
These all use a relatively small diameter inlet and discharge. It seems the two options are
1) a simple series loop with monoflow tees to go from 3/4" down to 1/2", supplying from and returning to the same 3/4" circuit.
2) run both a supply and return line around to each unit.
It seems like option 2 makes more sense, but I thought I'd see if anyone had other thoughts on this.
