Thought I would update the thread. We have a BIG house that is a fixer-upper, but we love it. The house originally had a drive in garage downstairs (1.5 car) and the previous owner finished it (but put no insulation). That is my attached workshop now. The entire downstairs in uninsulated (except the stove room, I did that 2 years ago). Our family room is where we have the stove, it is a big room (550 sq feet). The other rooms downstairs had to stay shut up with the old stove, and even then if it dropped below freezing the heat came on by 4am. So now picture a 3,650 square foot split foyer house, with the entire downstairs (save for 2 exerior walls in the stove room) uninsulated with the original windows from 1962, and trying to heat that with one stove.......
So we had a few cold days in a row with lots of wind, and I really got to test the stove. I have been bragging about how I am only burning pine and it is keeping the house warm, but in fairness I live in a moderate climate.
That said, Saturday night it was 24 outside when I went to bed, 18 when I woke up. I stoked the stove with a mix of pine and oak (50/50) at 8:30pm. When I decided it was finally time to go fidget with my IS on Sunday morning (8:30 am) it was 78 downstairs (opposite end of the room the stove is in) and 68 upstairs (down the hall outside our three bedrooms, as far from the stove as you can get). We have decided to shut my workshop (600 square feet) when it gets really cold so that the bedrooms stay a little warmer, but other than that, it will certainly heat the rest of the house. If my wife were more like me, I would leave the shop open and it would do fine for me, but she likes it a few degrees warmer when she wakes up.
Here is a picture of the thermostat in the stove room from Saturday at 11pm. I decided to see how well it heated and got the stove up to 625 surface temp (on the plate that covers the top flue exit, since we rear vent). So running hard from 8:30 - 11, this is what you get......
Now that is in the room with the stove, but still
I think if I got my lazy butt downstairs sooner, I could have kept the upstairs 70 with all the rooms open.
