I would LOVE to replace our Baby bear with something more efficient. The issue is, the chimney was constructed specifically for the baby bear so I’m not sure it’s even possible without having the chimney completely redone. Thoughts? We use this stove daily in the winter in addition to our gas furnace but it heats nearly the entire upstairs a few degrees with a massive ceiling fan circulating the air. We have a modern insert in our basement and it is just so much more efficient. I’m attaching a photo of the baby and the room itself (a chair is blocking the stove in the room photo). This was an addition to the house and is a brick chimney on an exterior wall. The original owner claims this was added in 1980. TIA!
