If we get the stove going on a good load, that means it's running around 500 °F and that will put the room and surrounding area in the low 80's. Right now, using a box fan at opposite end of house to move cold air which works pretty good; gets that end around 70 °F . Thinking about running dedicated duct from stove room to end of house with in line fan. (posted those questions over in the DIY forum). Our area here in MI has been above normal and we have only burned through a face cord of the more junk wood and have stayed very very comfortable. This stove keeps kicking out for hours after the fire is gone. :coolsmile:
