Here’s a useful heat transfer calculator. Based on this calculator, a 10 x 20 foot wall made of wood one foot thick with an inside temperature of 20 degrees and an outside temperature of -30 will loose 416.63 BTUs of heat each hour. If we imagine a room with four wall of this size and two walls that are 10 x 10, the total heat loss per hour would be (416.63*4 + 208.31*2) = 2083.15 BTU/hour
Wood stoves generally put out about 20 000 - 40 000 BTUs/hour, which means
they are more than sufficient to maintain the temperature of the room,
once it has been heated to 20 degrees.
