    A reference

    do you have a reference for the amount of BTU per hour the convectors will produce at 214 F -- steam temperature?  If so, I'd be inclined to do it the same way I would a system with radiators -- add up the demand from the convectors.  Then you could divide by 240 which would give you an equivalent EDR, and go from there.

    and......

    since convectors hold so little heat, you can probably go very light on the Pick up factor, 15 to 20% is probably plenty, if all you piping is insulated or you don't have an unusual system
