I have a 9 x 7 that I have heated with wood for years. The heater I use is made by Nu Way, they have a web site. The stove kit is $90. It was the only wooddtove I could find that was small enough. It works well. It is more difficult to regulate the heat with wood. Starting it is not a problem, no gas or fuel oil involved. I like the wood stove and would not switch, but it is more work than propane. If you do go propane make sure it is a high quality stove.

i have made 2 of my own woodstoves and they work well. if you dont maintain the fire well, then you do get varying heat output, but it has worked well for me. i only burn oak and other hardwoods because they burn longer - less stoking - and they also put out the most heat. im kinda old fashioned i guess, but there is something about having wood heat as compared to propane. it warms your bones, and propane just heats the air. ok, nostalgia overkill.....

I had a wood stove in one of my perms years ago. The novelty did not make up for the inconvenience. NuWay makes nice propane stoves that are vented to the outside. You can get the nice warm feel of a wood stove since the moisture from the propane is being vented out but don't have to be swetting one minute and then cold the next.
