If you use a wood burning stove, you would love to use the heat of the smoke that goes up the pipe to the chimney for a practical purpose, rather than mostly waste it … this oven will do just that.
The oven is a double walled box. There isn’t any smoke going into the baking chamber. The smoke comes up in the bottom, around the sides, and then out at the top.
Bottom right corner has access point to clean the chamber.
This specific product was sold by Lehmans, now they sell an integrated stove oven.
