I have looked for an answer before posting, but I was out of luck.

Why are Blaze King Classic Btu's so much lower than other large fire box stoves? For example, the Equinox has 62,675 BTU/hour on low...

Everyone speaks of the Blaze King as being a serious heater, but where are the Btu's?
 
One advantage of the BK's is you can turn them down lower than non-cats, and they'll still burn clean.
The BTU numbers are kinda meaningless anyway, unless the Equinox runs through the wood at 7.4 lbs/hr. on low.
62675btu's rating divided by 8600 (btu per lb average for wood)=7.37lbs per hour.
 
Trust me..they are there.
It's a epa thing.
Burn one on high with dry wood and it will kick arse with the rest of them.
I just never find the need to do that.
Maybe if I was a blacksmith..lol.
 
Hi DP, BK builds stoves which put out steady heat for a long time, which gives them a 40 hour burn time rather than the Equinox's 16 hour time. They're designed for a different purpose. Both are great stoves which I would recommend to anyone.
 
Thanks you guys!

I thought I had made up my mind and was going to purchase the new Woodstock when it comes out. I went up to the factory a couple of weeks ago and they are great people.

BUT, I am concerned that my old, two story drafty house will beat down that stove so I started looking at steel stoves so that I can crank it when it gets below 10 degrees.

Seems to me like the Blaze King may be the way to go. It has the long burn times that I am looking for and the potential to roar when I need it to. It is just so ugly for a parlor stove and I am having a hard time overlooking this.

My summer will be spent redoing windows and caulking everything. I whipped my caulk out the other day, and my girlfriend was impressed that I could caulk for so long. She said I was doing a good job.
 
BK numbers are also average heat output numbers, not the max numbers under ideal conditions. Under ideal conditions they say 90K is achievable.

From page 15 of their manual.

The Facts On BTU’s:
There are only two rating methods that mean something to you the consumer. The first is the Btu output that is achieved
during EPA testing. This testing is quite complicated and costly milled woods are burned. This is a standard for all manufacturer
testing and is not intended to provide consumers with a model for how a stove will burn in their home. The second
method that counts is what Blaze King refers to as the “Real World†method. These btu’s are achieved during in
house testing using the same thing a consumer burns, split, dry, cordwood. In our tests, we use fir. The “Real Worldâ€
btu’s listed are what the average consumer can expect to achieve, with slight variations depending upon geographical
location, type of wood, elevation and the amount of fuel added. Higher btu’s are possible. If you were to stand in front of
your stove and frequently add fuel, burn the unit on high and have optimal conditions, the PEJ1006 could produce as
high as 87,500 btu’s and the KEJ1107 could exceed 90,000 btu’s! However, maximum btu’s would only be achievable at
certain “peak†times during the burn. Blaze King does not wish to mislead you so we give you all the facts.

Btu Ratings PE / PEJ 1006 KE / KEJ 1007
Average EPA Test Fuel (Low Burn) 11,989 Btu/hr 8,600 Btu/hr
Average EPA Test Fuel (High Burn) 35,550 Btu/hr 37,800 Btu/hr
Average Real World Btu’s (Low Burn) 6,400 Btu/hr 8,400 Btu/hr
Average Real World Btu’s (High Burn) 40,000 Btu/hr 47,000 Btu/hr

aint gonna say a word :lol:

but googled blaze king and thinking of upgrading to the king 1107 for next year ;-)

I would have to agree with the ugly comment, the heat output of these big cu.ft. stoves would be great, but I would hate the look of one in the middle of my living room. I wasn't feeling that way a few days ago when it was 0 degrees though.

Somebody on here just did a nice install in a very contemporaneity environment with a BK .
I'll try to find it..it really did look nice.
If anybody else can find the pic faster..post up..I'm pretty slow..lol.

I have wondered the same thing. I'd hate to buy one of these things only to find out I should have got a higher output stove.

I'm trying to get use to having that front loader washing machine look in my new den, but I'm not there - yet ;)

That install looks great!

Not bad for a ugly BK eh? lol
 
Mines nowhere as nice..but I like it.
Before the stove was fired..but a non cat BK sat there for 24 years.

The King is undersized for our current heat load but I have been impressed with the heat output range of the stove. The same load that I can encourage to burn up in 8 hours now going balls to the wall will burn 48 hours in mild temps. Don't think I have seen another stove that can do that.
 
Question:
Have any of you BK owners measured how many pounds the stove normally takes in 24 hours?
If so, just take that figure and divide it by 24, then multiply the result by 8600, this will give the average gross BTU's
Take that number and multiply it by the efficiency listed by the manufacturer, i.e. 85%
This will give you the NET btu's which is how many btu are actually going into the building.

Beat me to it. :lol:

I wouldn't touch that pun with a ten foot pole, if I had one.

Nice picture and stove will the Blaze king outdo a PE summit?Thanks

Sir, tomorrow I'm going to either have the exact stove you have or A PE summit,what I'm trying to find out is can the Blaze King be run with the bypass open for fire viewing,and for how long and will you still get heat. This is a wife thing ,will itb damage the stove? This scenario would only be during the winter months for no more than 2 hours a day in the evening. Thanks
 
You don't have to open the bypass to have a good looking fire in a cat stove. You can either turn the air up for a lot of flames or turn it low til the flames slow down and start to float and roll above the logs. Lots of videos on youtube.

I agree that's the best overall approach, although one can quibble about your numbers (which I believe to be on the high side).

Unfortunately, weighing a single load of wood tends to be messy and laborious, especially if one is trying to fit as much as possible into the fire box. Also, because of the variation from load to load, one has to repeat this a number of times before obtaining a useful average number.

An easier approach for those of us burning 24/7 may be to measure how long one properly stacked cord of wood lasts, especially if one can find a reliable estimate of the number of BTU's per cord for the type of wood being burned.

A more reliable method is to weigh a truck-load of properly seasoned and dried wood and see how many days that lasts or, when properly stacked, how many cords of wood this makes.

The reason that I am going into some detail here is that, whereas a pound of dry wood yields indeed pretty much the same number of BTUs, independent of the type of wood used, huge differences do exist in wood density and thus in the number of pounds that can be loaded into the BK's 4.25 cu.ft. firebox.

Burning low density wood (e.g. spruce), as opposed to high density wood (e.g. some species of oak) can easily lead to a factor 2 difference in BTUs from a single load!

Blaze King underrates all of their stats. Trust me, it HEATS! I have been burning mine solid since I installed it 2 months ago. I let it go out once when I was gone for 2 days but other than that it has burned solid and I only load it every 12 hours and it is still hot when I load it. It is the most amazing stove I have ever owned. If you want to heat your house, get a blaze king ultra. And now that it is shoulder season it is so nice to have the thermostat. I turn it down and it even burns longer.
