Ran (2) stoves last year, 1st quarter of the season was a country hearth 2500 (epa tube stove) after December 1st ran the BK princess.
Right off the bat I noticed less wood being used, and even heat coming from the stove (no rise and fall like my old stove, wasn't chasing my heat setting). I was under the impression that the BK would be a little more difficult to run compared to the old stove. I was wrong, the BK was just as easy, you just need to experiment with the thermostat air control to get the heat output you desire, it takes a good weekend, about a 12pack and multiple phone calls to friends and family members that burn wood to brag about your stove.
To simplify this here's how I light my BK stove - From cold start - open bypass damper, turn thermostat air control all the way up. Load stove with newspaper, kindling, splits (you must have a dry wood supply) light fire, close door but don't latch it. Let the fire become established after about 5-7min from initial lighting shut door completely. Let the stove continue to burn full force, after 10-15 minutes start taking notice of the cat thermometer - the needle should start moving towards the active range. Once the needle hits the active range close the bypass, but keep the air setting all the way open. Since the bypass is closed the stove will heat more quickly, the catalytic converter will start burning more & more smoke producing more heat, once the cat thermometer hits between noon and one o'clock its safe to start closing your air supply to your desired heat level. Total star up time from cold start to active cat takes between 20 - 30 min.
To load more wood on an established fire (active cat) - turn air setting up, open bypass, open door load *dry wood in stove, close door, (I wait until the bottoms of the pieces start catching), and as long as the cat is still active close the by-pass. Keep air setting open, wait until all pieces are blazing (established fire) then close air control down to desired setting. total time about 5 min.
Now this my seem like a lot of time / baby sitting, it isn't because your only really loading your stove 1 to 2 times a day if your burning low - medium. If it get really cold out and you need more heat, you simply turn the air control to a higher setting, but the more heat you call for the faster your wood is going to burn. For me - air setting of 2 3/4 meant that the stove would go through wood like my old one, but even with the arctic winter we had I only ran the stove high like that a few times.
These stoves are meant to burn low and slow, once there's an established fire (lots of flames & active cat) you can turn the stove down, there will be a point where the stove gets turned down and it just glows, no flames, some people have there glass go totally black - but the cat probe will still maintain its setting, this means the stove is working as designed, I call this boring stove mode. BK recommends after running the stove on a lower setting for a period of time to do a burn off, what that means is after loading the stove and having a established fire to keep your air setting at the highest setting and letting the fire burn fully for about 30min, this will clean the inside of the stove, and the stove glass.
