Reusing an electric or gas oven as a wood burning stove...

Has anyone ever burned wood inside an electric or gas oven? I was thinking of modding and oven with refractory cement, and a water mist sprayer,for bread baking, when it occurred to me that broken gas/electric ovens are cheap, mostly air tight and temperature resistant,to say the least.
Obviously burning wood in them is not an UL approved usage, but clearly these devices are tested a lot more than your average barrel stove design..
So, any experience with this idea?

The basic oven construction is steel, which can withstand the heat. The excess heat that steve stroud mentions may cause glass enamel to crack off. If this happens it would be good to be in a location you don't mind tiny glass shards.

If the steel is also coated with zinc, ( I dunno if it is) it could burn off. Burning zinc is rather toxic. U may wanna research whether any parts you keep on it are galvanized or chromed.

electric stoves have wires running through them that are heat resistant but not fire prof (ask a fireman about kitchen fires) and yes the metal is thinner than a 55 gal drum. but if you lined where the fire is going to be with fire bricks you might get some use out of it. you will be doing this out side I should hope!
SInce most ovens work at less than 200 C, and most woodfires run at >500 C you have a basic problem

Thank you!Exactly the kind of stuff I wanted to know.
On the other hand,they are surely more heat resistant than 55 gallon drums, the standard vessel for DIY wood burners.

I'm not sure that is true. Oil drums are much simpler in construction, there's nothing there but thick steel.

I'm pretty sure that drum steel is thicker than oven steel.
Horizontal wood burners in drums often line the firepit with firebrick to protect the steel.

A good point. You should just give it a try and write an Instructable on your findings.
