I hate to start the combustion air thing..... but here goes. Would it make a difference in he stoves ability to heat if the combustion air were drawn from a separate part of the house/outside? I have read several differing thoughts on this, and I am still unsure. Sense tells mes that drawing cold air from "elsewhere" is more efficient than using already heated air, as well as causing a slight negative pressure around the stove, drawing cold air in through cracks, or other parts of the house. What are some thoughts on this? More efficient/heat or not worth it?
