All the time I've been reading this forum, it never made any sense that just burning less wood is the way to less heat. Every stove does have a certain minimum load to operate effectively, and I'd guess the larger the stove the more wood, Plus the more massive the stove, the more wood. BUT...I'm sure it's not that easy. If a large stove, let's say a Mansfield or Woodstock Paladian or PE Summit, Then the difference in mass of a stove would seem to be a factor. Does a more massive stove have more or less ability to put out lower amounts of heat (operate with fewer splits) than a equal size firebox with less mass? Many have said that runnig a stove full out most of the time is most efficient, but I doubt that we all do that.
