don't fire up any stove in a enclosed room, a low concentration of 0.1% CO in the air will take up about half of your bloods ablility to transport O2. (dead in a few hours) It's not hard to get to those levels.

If you ventilate well you can have a small stove/fire going on indoors. Properly ventilated places also have dryer air, which is easier to heat. However if you plan on burning anything indoors, i would highly recommend a CO detector and a fire extinguisher. Although a CO detector can be pricy, it's certainly worth it.

Just running a stove, will not heat a space efficiently. Your beter of with a catalytic heater (will also produce some CO !) or have a thing to transfer the heat of your stove to the air in the room. I know a trick to do that, but i don't know how to explain it properly. WIll try to find a picture.
