Just do what works for best heat.
Keep in mind that working a valve stem will eventually lead to
leaking around the packing, older the valve the more likely.
Also that some valves have a backseat so that when fully opened there
is no pressure on the stem packing.
I would open them all fully, and only close down if there's too much
heat. Like uncomfortable in a room.
I wouldn't be opening and closing them all the time.
