Been thinking about this phenomenon and I suppose an open fire or properly vented woodburner must draw moist air from the house and away up the chimney presubambly circulating air and essentially dehumidifying the house as well as providing heat. I guess the flipside is that it must be drawing in cold air from somewhere so might it make further reaches of the house draftier.
A stove will draw air in from near the floor where the colder, damper air will be, heat this air and lose it through the chimney, drawing in more damper, cooler air.

That's why they'll dry out an inside space as well as giving off loads of heat. Most stoves/burners are 75-85% efficient, whereas an open fire is about 25-30% efficient.
