I have an all nighter big moe, its served me well for about 12 years. I have an 8" hart and cooley stainless chimney. I am considering replacing it with a newer stove to save wood. Is this reasonable? Will a newer epa approved stove really burn that much less wood? My all nighter heats the bejeesus out of my house, but will chew up couple arm loads of wood every day.
