We are going to build a straw bale home and we are going to put a oven in it, can a double chamber oven with proper chimney work (winter use only of course)? Also can one use a L shape rocket mas stove?

Also one like this outside. http://www.livingearthstructures.com/projects/Cobzebo%20in%20Cobtati Can the Double work?

Thanks

Edward

Short answer...Yes, but typically not considered a DIYer basic project. I would suggest studying as much as you can about masonry heaters, ovens and recommend reading as much as you can about them and the medium of clay building.

I know the typical small rocket stove has an L-shaped flame path, but why do you want to use that style in a larger indoor unit? The J-tube has been found to be more efficient in combustion, it self-feeds as long as the sticks in the feed tube last, and its ergonomics are better adapted to typical American stand-at-the-stove practice. (Cooks in third world countries the rocket stove was developed for tend to squat at the fire to cook.)

What I mean by L shape is the bench part not the stove. Example... start at the NW corner of wall go south the length of a couch and then go east the length of a couch, L shape.

Aha! Yes, you can make any shape bench that fits your space, as long as you remember that every 90 degree elbow reduces the duct length by about 5'. If you would need a very complicated duct route, you might be better off with half-barrel bells in the bench instead of ducting.
