So yes, I am brand new to this forum. Just happened to stumble across it while trying to research outdoor furnaces. Thanks ahead to those who have contributed. I plan to spend a good deal of time looking though old posts, but I thought I'd post my situation in case someone might be willing to give their two cents. So here goes.
I live in Nova Scotia in a story and 3/4 (~1,600 sq feet) 150+ year old house that has average insulation and new windows. The current heating system is oil forced air, but we heat almost exclusively with a Napolean Wood Stove. We burn somewhere between 4 and 5 cord of fairly well seasoned hardwood (maple, birch, etc). However, we are seriously considering moving to an outdoor wood furnace in order to get all the wood, insects, dust and danger out of the house. I'm aware of the cost involved here (~$15K for the complete install) but have no issue with this if the system is right for our situation.
While I'm currently burning the typical hardwoods used for firewood in our area, I have to buy it because we don't have those on our property. I would be looking to burn almost exclusively poplar and spruce because we do have an endless supply of that on our land. This is another part of the reason we want to get away from the indoor wood stove. I'm scared of the added creosote that could come with this type of wood.
I'm in the process of investigating the Empyre wood furnaces because a relative of mine has had very good experience with the Deluxe model. I'm leaning towards the same (not high efficiency) because I can't guarantee that everything I burn will be completely seasoned. Also, I've heard bad things about the high efficiency units rusting out because of the fact that the fire boxes and other parts aren't stainless steel.
I'm open to suggestions or questions about direction I'm headed. Also, if there are other makes of unit that might be better than what I'm considering, I'd be more than happy to listen. Thank you.
