I was actually driving all over Bucks on Saturday, when this was posted! Family is from New Hope, or specifically the farmland south and west of town, and I grew up just a few minutes WSW from there.
Anyway, I couldn't be more thrilled with my BK's, they've really done well for me, despite some pretty hard use and a total lack of attention or maintenance on my part. I'd guess I have 80-90 cords thru the pair of them, still on their original door and bypass gaskets. I haven't even pulled the chimney off either since 2015, but I do plan to bore-scope those this year. I started my own business in 2022, and so things have been beyond crazy-busy, recently.
I've operated these stoves in a few different modes, as my work and home life situation has changed over the years. I used to load one 2x per day, and the other 1x per day, on near constant clock cycles with the burn rates adjusted to be down to barbeque coals just prior to reload. They are wonderfully consistent in that mode, putting out surprisingly even heat over the entire cycle, thanks to their thermostat behavior. But now I'm home all day, and my desk is quite literally less than 15 feet from one of the stoves, so I've fallen back to a mode of just loading it when I feel I want more heat, and they work great in this mode too.
PM me if you want any more specifics, since I don't check this forum too often anymore, due to the obnoxious advertising that makes surfing this forum much less pleasurable than it used to be. If you PM, I should get an email, which will remind me to check back.
To the new hearth.com site owners, from an older member: your advertising is ruining this forum! So many damn banners and pop-ups on this site anymore, you can't even get to the basic navigation button without clicking to hide the advertisements. Absolutely the worst forum I've seen in a long time, in this regard. It's the primary reason I don't spend much time here, anymore.
