I think it's there to be able to set it for whatever works best for you...
Full blast.... snail speed... or somewhere in between.
But the thing is, they don't move tons of air, relative to the amount of
heat mass in a coal stove.
I doubt you would see much difference to be honest. (in stove temp)
Yes, the air coming out may be a tad cooler than on low, but there is more of it.
Put another way, You can blow out e.g. 50cfm at 135°, or 110cfm at 100°.
You will probably get as much heating value in the room,
either way, as you are reheating room air
that you are scrubbing off the stove. It's not like taking outside air in,
and blowing the same amount out the chimney.
Biggest difference may be that you are moving the air more, in the room,
with the higher setting.
But I don't really know...
