We have used an electric blanket or sleeping bags when it is cold weather camping. I know there has been discussion about heating without shore power so I started to day dream.
Eventually I thought of sail boats. How did the old sail boats warm a cabin safely? This lead to small charcoal heaters, which lead to an idea.
Safety! I know a fire around a wooden structure is dangerous no matter how well designed. With this said, here is what I've come up with.
Keep the main burner on the outside. The back of the main burner will be a panel larger than the small stove. This allows a section to be cut into a wall or door and the stove installed in its place.
Since the stove is outside, the outer 3/4 of a square or 1/2 of a cylinder would be insulated for efficiency. The chimney would also extend up the back panel of the stove giving up heat. We should think of the chimney as more of a long stove as it extends up the back panel. All fuel would be added from the outside, as easy as opening the camper door and dropping in a briquette from the top.
No, I have not made the stove and am not likely to do so. It is just a fun idea I can't get out of my head.
