I know I have a few posts about my future plans but, the more I think I'm jus not sure on what to do. I've been dead set on the bk insert for a year or so but now that the time has come I'm thinkin maybe an add on furnace. I know nothing about wood furnaces. The more I try to research, the more I still don't know! My current flue that already has my liner in it goes all the way to the basement so I was thinkin of runnin more ss flex thru my fireplace an maybe covering my fireplace opening in my living room. Would I see the same burn times in a furnace as the princess? Would an add on furnace be worth the hassle? Getting it to the basement, wood down stairs, piping all of it, ect....Sorry if this is all rambled but thanks for any input
