The outer brick never gets hot. There is some smoke on start up and once the fire is burning there is no visible smoke. On very cold days you can see steam; it does condense to water if you hold a mirror in it.

Even so, this stove keeps providing amazing heat. The steel did burn out of the secondary burn tube, but the ceramic insulation became stiff and hold its shape and function without fail! It can be reached via the oven/clean out door.Secondary pre heated air is provided by a iron pile in the top of the burn chamber into the secondary burn tube, makes a nice wood gas flame! It should have been taller. It's not perfect, but we did not have floor space to waste. I think it is efficient enouy.
