Nice. Burn time on full load?
I burn this stove pretty hard to heat an 1800 sf building with a bigger than oem blower plus convection deck.

Burn time is very consistent at about 3 hours for a full load of Doug fir firewood packed to the top. That’s 3.5 cubic feet of fuel per 3 hours. I’ve been able to do 3 back to back loads at that rate. These bark loads burn just as fast but I believe they are lighter so less heat is released.

I aim to hold 700 degree stove top temperatures which is way below the safe limits for a steel stove.

Yes, a wood furnace would be more appropriate but none are clean enough to be legal in Washington. Not even the kuuma.

Thats not too bad really. Might have to give it a go with my maple bark and scraps. Been thinking of making and "uglies" bin from an IBC tote I have laying around.

I just hate to waste it. The maple bark is thinner but if it’s dry will burn fine. This fir bark sat out on that gravel road all summer drying out.

I did a full load of bark/chips/sawdust/etc last year. It didn't burn as long as a full load of wood, but it burned completely, which I didn't expect (I thought the stuff on the bottom wouldn't burn due to air not being able to get down there).

It needs a lot more air to burn clean and hot in my stove so it really burns in a front to back manner. Like a huge cigar. Not many flames after the first hour or so.

I'm like you, I hate to leave BTU's to rot. "Waste not want not" is my motto when it comes to firewood. Stuff that won't cut it in January will work fine in November.

At the least it would be good for fire pit wood.
