We're just getting through a cold snap complete with weather inversions and thick fog, burn bans, low 20s every day which for WA is pretty dang cold. I had to run the princess as hard as I ever have and really have to recommend the fans. Those fans strip heat off of the stove very fast and allow a rapid heat up of the room. Very impressive and worth the noise.
I also got to run a load above 2. Still at the top endge of the "normal range" so about 2.25 and the stove was flaming for nearly the whole load. I don't think that these cat stoves are really good at burning clean and hot, seems lots of pollutants make it past the cat at high burn rates. I thought it was steam but the smoke travelled quite a ways.
Do your BKs pollute when burned at high settings? Is that a normal cat thing? As the load burned down, the smoke cleared up.
Yep, I see smoke at 2 and above but rarely have to burn that high. My Woodstock will throw smoke at higher settings as well.
