For those that are on the fence with the Bk, let me tell you about my past 23 days. I've owned a bk now for 5 seasons, I have a princess with a strait up flue approx. 18ft in height, I burn a mixture of oak, maple, ash, with some black locust mixed in, all the firewood measures between 14 - 18% moisture content.
I main job is a utility worker and living in NJ some off you guys know we had a rough start to March, actually we have had a rough March, I went to work on March 2nd and worked 16hr days until yesterday March 23rd. In that time I've had multiple days were I couldn't make it home due to multiple harsh winter storms.
The BK did fine though, in that period of time I never had to use matches to re-lite the stove. I would fill the stove box to the gills twice a day, once around 4:30 am, and then again at 11pm, I would burn low during the day and high at night, the house temps were consistently between 74deg and 65deg at its lowest points. The back up heat never came on. Outside temps were in the low 30's during the day and upper teens at night.
The last leg of my OT journey landed me in south jersey for 2 days, I wasn't able to make it home, surprisingly though, when I came home last night, I had enough coals to rake forward and do a simple re-lite, The BK line up is like no other in my opinion, I will forever have one in my home.
