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.
These stoves are bad to the bone.
Not bad at all from a stove less than 3 ft3.
