Hello all, been awhile since I've been on. I have a nice big Morso 3660 in my living roon that does a great job of heating my home about 90% or so of the time in the winter. But due to some circumstances (divorce) I will no longer be in the house to split wood and maintain the system. The soon-to-be ex-wife has always complained about the mess and effort involved in having a wood stove, while I have always enjoyed the chores and the forced exercise it gets me as well as the silent operation and amazng cost savings versus oil heat (saves me about 1200 gallons of oil every year). So the wife is considering putting a pellet stove in place of the wood stove, I've tried to warn her that it might not be the best choice because I'm skeptical she's going to be able to find a stove thats going to be up to the task of heating that air volume (log home with a massive great room, 26' ceilings and the room encompasses easily 3/5 of the interior volume of the house). So my question is this, does a pellet stove need to be direct vented or can it be tied into the existing chimney I put in for the wood stove? Its a straight vertical shot of 6" double wall metalbestos with 6" triple wall going through the roof. Can the output from a pellet stove simply be tied into this chimeny or is it going to be a bit more complex than that?
