The
The problem is that it doesn't keep my house warm I have a very old drafty house but it just doesn't keep it warm over night we have to set it at a 2.5 to keep warm and the wood burns quickly that way with Temps below zero very quicklyI can see negative draft putting out the fire and driving smoke out of the pipes, but smoking out of the back of the stove? Don't know enough to say if that's normal under backdraft conditions but guessing that it's not.
Also, he's not just running a little hot to prevent backdrafts- if he's filling a 4.3 CF firebox 3x a night, that's a crazy amount of heat. If I burned my princess hot enough to consume 12 CF of wood per night, I'd have to sleep outside, with breaks to go inside and wet down the sofa every hour or so.
