    The thought just popped up in my head. If you built a masonry heater and then a house around it, would there be any benefit to designing a secondary air system into the heater? Since they burn all out, would the secondaries add or detract from smoke output/ build-up in the stove? Just curious. JB

    I think you want all the heat to travel through the labrynth of flue so the heat can be absorbed by the masonry, a baffle and/or secondary air system would prevent a lot of the heat from travelling.

    Would the air drawn in and burned in a secondary tube(s) really cause that much heat loss?

    Many masonry heaters incorporate secondary air systems, I believe.

    Honestly, I've not dug into the designs too much, but I haven't run across a secondary air supplement/design so far.
    The desired result would be as little smoke from the flue as possible, for as short a duration of the burn as possible.
    I don't have a clue, that's why I ask. JB

    I havent either thats why I replied as I did, maybe they would work better but cost more or maybe they dont make enough difference to bother.
