To get the best results you will wnat the following:
Measure the heat loss of each room. Put sq ft of EDR radiation in that room that matches the heat estimate. this means that finding the heat estimate of each room is important so you can replace, swap, or dissasemble and make smaller radiators in rooms wher radiators overheat the rooms.
Be sure the ends of the mains have good air vents, so the vents in the radiators don't have to take over for them and therefore will just have to control the room heat, not vent the air for the other radiators. Thus you now have steam air vents that can not be adjusted.
Be sure the input of the boiler matches the total sq ft of radiation close enough to keep the burner running most of the hour during the coldest weather. Short-cycling and having to take in and vent air many times and hour makes the heat uneven from room to room.
After the system is balanced out, fine-tune the far rooms with non-electric steam vents.
