Here, the dark areas of the radiator show where steam just isn't getting to. The occupants run their hand along the top, consistently the hottest part by far, and think the steam is "working perfectly", but there is about half this heat emitter not doing any good for the temperature of the room.
Moving this improperly placed air vent to the right location on the radiator will allow the whole thing to heat up, and transfer a great deal more heat to the room.

Thermal imaging cameras are an invaluable troubleshooting tool.
