Begreen is always great for bringing us back on point. He has to wrangle us BK owners a bit, since we are such big fans of this brand, but with good reason. The same can be said for Woodstock, they are a fantastic company, in every way. If other brands receive less praise, it's not by accident.
Ashful i am curious about those burn times as i have not personally owned a bk. Is there anyway this next season when you burn you can load up and show every hour or so what the firebox looks like on a say 35 hour burn and put stove top temps as well. I know it would be a little bit of a pain but if you could do that it would personally help me out. Are you getting solid heat from the bk for 35hrs or maintaining embers.
So this brings up the usual disclaimer, BK's are great stoves, but they are not magic. In order to stretch 35 hours out of a single 3 cu.ft. load of wood, you must burn at a very low rate and the heat output will be low. The firebox will be smouldering black box, just producing wood gas for the combustor to "eat". The combustor will average 750 - 1500F over the first two thirds of the load, and this becomes the primary source of heat. The convection deck on the Ashford 30 directs air flow across the top of this combustor, extracting the heat.
The reason we like this capability so much is that it's just more flexible to have a wider range of output selection:
1. It provides a more constant temperature than the uneven/cyclical heat output of most other stoves.
2. It gives us an ability to burn on days where other stoves might overheat the joint.
These comments are applicable to any catalytic stove (begreen), although BK really does this exceedingly well.
BK's of course are great stoves. Just wanted to know it's superiority. Ashful how many cords do you typically use in a heating season and how many square feet are you heating?
I am heating about 7600 sq.ft., but less than 6000 sq.ft. of that might be considered stove load. Of that total, about half is un-insulated mud-stacked masonry construction (mid-1700's) with original doors and windows. I have 60 windows and a dozen doors, about half of which are more than 200 years old and not what one would call air-tight.
I use 6 - 10 cords per year, depending more on my ambition and dedication than my heating needs. I load one of my stoves 2x per day, and set the thermostat to a position that ensures a complete burn over that 12 hour cycle. I load the other 1x per day, and accordingly set that thermostat to a position that ensures a complete burn over a 24 hour cycle. I let the central heating system(s) pick up any slack, and parts of the property not connected to the stoves. I'm in this to save money and have some fun, without driving myself or my family insane.
