It's a matter of preference.Zone valves are fine.Also, Honeywell makes 1" zone valves( I just bought 10 model 8043 1"). 100 feet is alot of baseboard for a 3/4" line which is why it's a 1" line to begin with so be careful there. I would NOT downsize the piping on the 1" line under any cicumstances. It's 1" for a reason and there could be negative consequenses(ie not enough heat at the end of the line)as a result. The indirect will need a circulator. I'd go with zone valves but, again, it's matter of preference. Just make sure to put service valves before and after the circulator and also be sure you can isolate the boiler from the system so in the event you need to do service to the boiler you don't have to dump the entire system.The contractors are both 1/2 right(or half wrong) depending on how you look at it. They sound like plumbers talking and not REAL heating contractors. Remember, most good heating contractors don't do plumbing. My apologies to all the plumbers who do happen to know their way around the boiler room. You are few and far between. Good luck!
