A small circulating fan is usually always an improvement over straight

Not really, AFAICS the old designs tossed the hot gasses/smoke and a lot of
room air right up the flue. Franklin's innovation was in the use of materials
that would not crack under the uneven heating that was going on in the
fireplace inserts of the day. And, of course, the revised path for the escaping
gasses.

From the amount of brandy in it I would expect them to be somewhat hammered in
