I don't see anything disturbing about that.

I agree. Remember herdbull, you are measuring the Very hottest part of the stove top. The entire stove top isn't 800°… Only that one particular spot. If you were to average the temp, throughout the ENTIRE Stove top surface, its likely gonna be somewhere around 600°-650°

The impingement plate thats in the stove top (above baffle board/just behind the step top) causes the hot air to stop there and go around, so the temps there are much hotter. Because of these temps, I have put 3 thermos on my top. One on the front (4" behind brass lip on top) and one on each side of the flue connection. These temps are lower than right in front of the step top.

A stove thats around 250° after 12 hrs is pretty damn good, IMO. Ask the guys who are up twice a night to reload a firebox that's under 1.5-2 sq ft.

How tall is your chimney (liner) ?
 
The chimney is internal up to about 15' then there's roughly 5' above the roof.... minus the height of the stove.... roughly 17' liner length.

As for the temps? This is the scenario on most 3/4 full loads I run. Due to the wood I'm burning being shorter I've never really loaded this thing to the gills but it seems to touch 800 almost every load. Just seemed a little hot for my liking as I'm either gone or sleeping when it does this. Not that being around would do much but I could tend to it if things got out of control.

I forgot to mention I haven't fidgeted with any air controls after the initial 500 degrees. I wanted to duplicate a weekday burn when I'm gone for work.

I got 4 hours and 10 mins at 500 or above. More than I expected as it appeared after she spiked most of the outgassing was already done. There was minimal secondary burn from 550 down to 450. I'm now almost 7 hours in and she's around 375 but it's stalled out there, probably for another 2 hours. I love coming home from almost a 12 hour day and still have a warm stove and good coals to set off another one. I've been extremely pleased with the burn times.
 
How are you measuring the temps? Stove top thermometer or IR gun?
 
Both. The Condar is and has always been within 5-10 degrees of the IR gun. Amazingly accurate compared to some others.

I'm now 10 hours into the burn and she's still sitting at 325. House is pleasantly warm considering we struggled to see 20 degrees today. I'll probably let it go another hour before disturbing it. I think now having it stuck back into a fireplace is helping it retain heat better than being out in the open.
 
A final wrap up on the test.

At hour 11 I opened her up and found a substantial amount of coals and the stove sitting around 275. So I raked them for forward, cranked the air and within 15 mins temps were back to 375. They hung there for an hour and then dropped to 300. So after 13 hours I had a nice pile of coals and a stove that was still at 300 degrees.

All in all for me it doesn't get any better than that. I couldn't be happier and for the life of me can't figure out why I was wanting more. Don't ever let me talk bad about this stove in the future ;lol ok.

Just for giggles today I turned the blower on about 1/4 speed when I went to work this morning. 12 hrs and 15 mins later when I got home stove is sitting at 275 with another big chunky box of coals. Rake forward, crank the air open and it's still at 350 with the blower on 13 hours later. So why doesn't everyone have one of these?

Your results, although pretty typical, are a combination of good fuel and possibly a perfectly matched chimney. Remember "results may vary"
 
All of that I haven't been able to stuff it full yet because my wood was cut short at around 16" for the other stove. I'm thinking lining the back of the stove E/W with a few smaller splits and then the normal N/S load in front of that. That would fill the box completely and I don't see any reason why she wouldn't go 14+ hours above 275. Maybe this weekend I'll do another test.

I absolutely agree that the fuel source is a huge factor in sustaining these types of burns. Can't wait till I resupply with the next 6-8 weeks worth of wood from the shed. It's the good stuff saved for the dead of winter.
