I just purchased a Atlantic 228 airtight wood stove. I believe this stove is 10 to 15 years old except it is brand new in the box still strapped to the pallet. The lady I purchased the stove from said her husband bought two of these about 10 or 15 years ago, she thinks. The other stove was installed at her mothers house and is still working today. My question is what makes the new stoves more efficient than this stove? I notice there is no bricks in this stove and it has an oval sideways flue that will take an eight inch pipe. The directions also say something about a stovepipe damper. This stove will take a 24" log and can be loaded from the front or the side. It is a really nice looking stove. I am switching over to wood one way or the other this year. Do you think I should install this stove or get something newer. Will this stove burn more wood than a newer one and if so will it be a huge difference? Any help on this would be appreciated.
