Where did the 2" hose requirement come from?  Wasn't Tracy running with 5/8" hose to his radiators?  Can we get a survey of working installations to see what size hose is sufficient?

This is a significant issue for me.  I'm considering a remotely located radiator.  Running 2" hose for 7ft or so is out of the question.
