I was bored last night and knew our temps would be warm so I decided t to load the stove up and dial it down. I even weighed the load since it seemed like the right thing to do. :lol: I loaded around 11pm last night, I charred the load and dialed it down to "1" on the t-stat, when I left for work around 8am the stove top was 450ish with the cat still glowing, tonight at 7pm the temp was around 280, I took the temp picture at 9pm after turning the stove up.(fans weren't used except when charring the wood last night) The stove is back on "1" now and I'll probably let it ride till morning and see what happens. When it's burning on low the temps on the top are the higher temps due to the cat heat the rest of the stove is a bunch cooler, I think this is why it doesn't cook you out even when it's in the 50'/low 60's like it was today. It was 72/73 when I went to bed last night and I think it's 73 right now.

Obviously this isn't gonna get it done when it's cold but for this type of weather it's fun not over heating the place or loading small chase fires in the morning/evenings while dealing with cold starts.


Here is about 45lbs of oak and ash

22 Hours later, yes the glass is black that's the reason the door is open for the picture. :lol:

Wake up! How did it look this morning?

Stove top was at 150, raked the remaining coals to the front with the air turned up for a few minutes and just started another small load with no issues. So minutes shy of 33 hours later and still no match! 10 minutes after loading the fire is fully engulfed and cat is engaged. I'll post pictures after work....
 
What did you have in there??
 
Nice burn.
 
I have officially achieved 40 hours. I was getting the 'look' as I loaded it up Tuesday about 7pm (75° in here after having the oven going all afternoon). When I left the house it was a comfy 72° at 1am. I got home about 30 minutes ago, conjured up some coals, tossed a few small cherry splits in, and we're back to cooking. I know my wife didn't add any wood because the rack was as I left it.
I wish I was home yesterday to see how warm it was in here. I didn't get any complaints when I called home last night, and I forgot to ask. It was in the upper 60s outside, but with a stiff breeze, and I doubt much heat was coming off the stove.

Sweet, after 33 hours if you had a convection blower going it would still be blowing out warm air?

Probably not what I consider "warm", honestly the stove at 150 isn't putting off any real heat. When I went to bed the lower level was on the warm side for me in the 74-75 range(since I turned it up for a half hour or so to keep the cat nice and active) but the outside temp was also in the 50's. When I woke up it was 72ish so even with the warm temp there wasn't enough heat coming off to maintain the temp. I find most of us "Blaze King" owners start defining burn time different than most other stove owners. I now look at it as usable heat where I used to look at it as enough coals re-light full size splits with the non cat stove.

Yep, yesterday we didn't have a high demand for heat but if I had the furnace on it would've had to run to keep the place in the low 70's. These stoves make heating in the shoulder season easy. I may not have saved a bunch of wood but the house was a steady temp and I didn't have to dink with loading small fires.
 
Good report guys!
It certainty was a good day or two to run on "1" or low!!

Was it extremely windy at your places?
Cheers, Hiram
 
I was gonna check your math but I couldn't read the weight of the upper left splits. :lol:

I haven't loaded the Fireview to the gills with long-burn wood yet, as I easily get eight or ten hours on a partial load, and it hasn't been very cold so I can burn the wood slow to get enough heat. It'll be interesting to see how long it'll go on a full load. I don't think it'll be 33 hrs, though... :gulp:

Holy cat scat!!!! It was 67 degrees for the high on 3/7 and 62 on 3/6. Why would you even need a fire rdust?

Its been getting cold at night, we got down to the 20's two nights ago, last night stayed at 40 though, tonight back down to the lower 30's.
Oops, just noticed Rdust is in Mich, thought he was in Conn.
 
Are you guys loading your BK's full,to get the extended burns on 1,just wondering if my stoves capable.See I'm only running about a 15 chimney,now don't get me wrong I'm getting good burns but 33 and 40 hours I've yet to try.I honestly think my cat will go inactive at #1.Feedback please, I don't want to feel cheated.

If you let it get hot, then turn it down to 1, your cat will stay active

Simple answer would be I was cold! :lol: Well it was loaded Tuesday night and I'm pretty sure we had temps in the 30's for the overnight, yesterday was warm without a doubt and yesterday evening was in the 50's. None of those temps get me into the 70's where I'm comfortable so a fire is needed in some fashion. Burning a load of wood over 33 hours doesn't put a ton of heat in the house and keeps it right in my comfort zone. I put it in the area of running a 1500W electric space heater maybe a bit more.

I'm surprised you wouldn't need a fire seeing how you like your temps in the 80's. I can only assume your added insulation and windows are doing a great job if you stayed in the 80's during the same stretch with no fires! ;-)

Exactly. Just because 60 feels nice outside does not mean that 60 feels nice inside my house. Goes below 70 in here something is gonna burn.
 
loaded my stove the same way last night. its just easier to load it up and crank her way down then to mess with lighting a new fire. i haven't let my stove die now since october. house doesn't go above 73 74. either.
 
Just pulled the morning pics off the camera.

That last pic is a keeper.

I thought that one was a keeper! Too bad the door has to be open to get it! :lol:

I can post a link to the full res if you'd like.
 
A few years ago I loaded the 30 and started it up for the first time that season. Went in the kitchen and looked back at it and said "Whoa! Grab the camera.".

Edit to add: Door closed. It's a non-cat thing. Clean glass. We are big on that stuff.

Can you who burn at the low levels with the BK Princess as shown in this thread give us some idea how often you need to clean the chimney. I am amazed at the way the burn can be controlled. Are all the BK cat stoves equally controllable. Are there other stoves that are able to provide such long burns both cat equipped and non-cat? I might have to look for a BK model that uses a 6in chimney. Other than using well seasoned wood is there anything else we should know? I burn what the tree service drops in the side yard so it isn't anything special. It is always c/s/s for two summers. I'm sure there are others who are interested as I am.
Thanks
Tom

:lol: My glass typically is pretty good when I can let the stove burn the low burns will get it every time. I have a lot of pictures of my Endeavor burning with the door closed, my wife thinks I'm crazy when she sees me grab the camera to take a picture of a fire. :)

The fire in your picture looks very angry!

I try to run the brush up mine two-three times a season if it needs it or not. I get more than I see some people post but a couple/few cups of crap for 30' worth of chimney I feel I'm doing ok. I cleaned mine for the third time a week or so ago and that will do it for this season I figure. First year with this stove but the chimney seems the same as it did with my Endeavor.

The BK stoves like well seasoned wood and seem to like a good drawing chimney due to their low stack temps when burning on low. If the chimney or wood isn't up to par the cat can stall/go inactive on the low burns.

I burn mine on 1 (lowest setting) about 95% of the time. The only time it's not on 1 is when the stove has gone cold for sweeping the chimney, or on a reload. Being on 1 gives me about a 225-260 convection deck temp. The stove will be warmer on colder days, and colder on warmer days because of the draft differences. So if it's 50 degrees out, my stove will stay on 1 and the inside temp will be 72-74. If it's 20 degrees out, the stove will still be on 1 and it's still 72 in here. The burns will be a couple hours shorter when it's colder out than when it's warmer. (28-30 hours when it's 40-50 out, versus 24-25 hours when it's 20 out on softwood)

about 80% of the wood I burned this year has been a cottonwood/willow/catalpa mix with a bit of pine scattered in. The rest of the 20% I burned were 4x4 hardwood pallet pieces. Usually about 8-10 18" pieces were good for a 24hour burn. The stove would be a little over half full with that kind of load. The wood was pallet wood and I didn't season it, most of it was about 20-22% MC... Much higher than the 13% BK recommends you to burn. I'd end up burning the stove on high for a good while to drive off as much moisture as I could before turning it down.

I have a 16' chimney, swept 3 times this year. The first two times I got about a cup and a half of soot, then the last time I got about a cup. Flue temps on 1 hover around 190-200.
Longest burn I got was 36 hours on somewhere around 47lbs of Pine. I have the exact amount in another thread. that was going from cold to ~200 convection temp on a 40 degreeish day.
If I recall the low BTU output is somewhere about 4500-5000 after considering in efficiency. All BK models use a 6" Chimney except for the King.
