Basically you will be burning ( mostly) only the gasses and the majority of the fuel you will take it out as char in wich case you will be burning more wood ,probably double the ammount or more ( im optimistic but i think its 3-4 times).
If you want to make biochar its not a bad idea and any gasification type of stove should do the trick.
Its also more dangerous to have such type of stove ( used for charcoal making,a normal gasification stove is safe if you dont strangle the air intake to make charcoal)because the combustion happens with verry low oxigen and you get a lot of CO instead of CO2.Needs to be sealed verry well.

Have you been in contact with the sellers of that wood stove? I sent them a question via their web site several months ago and got no answer. It would be great to know if it's actually available.
