One thing you need to remember is that long burn times have a lot of gray area as to what they really mean.
I have a soapstone stove and it is will produce heat in the 450 550 range for several hours fully loaded but once it goes to coals it seems manufactures still call that in the burn time arena. So it depends on how you look at it. They say burn time I say reduced heat output time if you let it go for another 8 hours.
I reload my stove as often as ever four hours to maintain a temp of 5-550 but at night I can load and forget it and in the morning it will have a surface temp of 200 degrees but it only seems warm and not really producing a lot of usable heat compared to 500 degrees as there is a huge difference in how much heat radiates at those two different temps. But the manufacture would probably still call that in the burn time zone.
If ones house is super tight and there are some here that have that. They can go with one or two loads of wood a day but that is few in comparison to us with older homes.
