Hey guys, so I’ve been thinking lately that some sort of gasifier wood stove would probably be pretty clean and efficient. I know downdraft boilers are all the rage and extremely efficient, but it seems there’s not many options out there for an indoor downdraft wood stove?
I know of the tempwood stove
Also there is the Sedore, which is technically considered a cross draft
I’m curious if anybody has tried building their own gasifier style down or cross draft wood stove? Do you guys think an Imbert style wood be best? What about a fema? Since we are burning the gases I think it’s fair to say we aren’t too picky on the gas quality so long as it can ignite.
I’ve done some looking into rocket stoves and mass heaters, but honestly I think for the amount of work, no insurance and plain ugliness they are not worth it for what (possible) small efficiency gains they have. I understand their concept of burning quick and hot makes a very clean and efficient burn, but why not build something with a more slow and efficient burn instead? I think a down/cross draft gasifier stove may be able to do that quite well.
The tempwood is an insulated stove but has no baffle or means to try and keep the heat in the stove longer for a longer heat output, and the Sedore uses no insulation, just perforated steel, so I think between these two designs there is definitely some room for improvement.
Anybody done this already or have any ideas?
