Ive never had any of that happen. Ive try all wood types same results even wood with 10% water. Just in the time in took me to type this its back to 1Cherry is not the highest BTU wood...but a box full of it ought to heat your house this time of year.
The last time I had the firebox stuffed full was last January when the high temp for the day was around zero...an the computer on medium, loaded every 8 hours or so IIRC...a couple times the high temp alarm went off because I loaded on too many coals, and had a full firebox of real dry wood...went 3, 2, 1, c real quick, and stayed on c for a LONG time...2 hrs maybe? CRS n all....

Sounds pretty good.
The back of the stove was empty? You mean after you pulled coals forward?
Just make sure you keep the coals away from the front plate like they tell you to...I have been into a few different Kuumas now and I can vouch for damage to that area just as the decal (and manual) say if this is ignored...
yes I pull them forward and then push them off the front thats what Dale told me to do

Do you have the thermostat hooked up to it and is it calling for heat (which puts the blower on high)? Make sure the blower is running on low.
I just use an indoor/outdoor weather "station" and put the outdoor sensor in the blower box. Make sure it's tied down to the metal good though, as you don't want it getting sucked into the blower. LOL
100° plenum temps really won't cut it. Sounds like you may have a similar situation I was in my first winter. I too was seeing low plenum temps similar to yours......and lower than everybody else with a Kuuma at the time....barely over 100° at the highest. First thing I did was I restricted my duct some to increase my static pressure (as I had VERY low duct pressure originally) and that helped some. You could always try putting in a couple higher MERV rating filters to reduce the volume of air being sent through the air jacket and see if that raises the plenum temp and if it does, see if it heats the house better. Bottom line is, for our house, the factory blower setup was not optimal..........I slowed my blower WAY down to increase supply temps and it heats our place sooo much easier now.

Its doing what its designed to do...modulating to keep the fire in its optimized state...burning clean, and hot!
I used a meat thermometer. I know thats not good its what I had. Ill get something better

I started to type the same thing...then I went back and re-read...he said register temps...100* register temps is all I get...works fine. But I caught my misread in time....
sorry yes that was the closet one from the stove maybe like 3 feet awayI started to type the same thing...then I went back and re-read...he said register temps...100* register temps is all I get...works fine. But I caught my misread in time....

its very close prob less then 3Oh...well that is almost the same as plenum temp then if its that close...

Most don't use the thermostat, just run the blower on low. I haven't heard of one person yet say they achieved better results with running the blower on high.

Stole my thunder here...excellent advice...even just going to cheap pleated filters might be enough to whoa things up enough...but just letting it go to low will help a lot...I don't even have my tstat hooked up.
I too get great results with "low n slow" on the blower/air speeds

The wood boiler guys have the same issues with setting up their water circulation speeds...too fast doesn't work, too slow doesn't work...although we can get away with some pretty slow air speeds...
thats amazing that works I would think faster warm air would heat better. Ill try it though I dont have much to lose at this point. Im starting to wonder if the house is leaking to bad and my old stove was just hiding it but it was 40 outside today and it couldnt get passed 68

That's just nuts!!
I loaded 31# of wood at 8am and the house went from 71* to 75* and I still haven't reloaded...was still 72* in here the last I looked...I think we had about the same weather today.
Where are you in PA again?

It's not faster warm air though, it's faster/higher volume cooler air. When you slow it down it becomes less volume of warmer air. My theory is when you slow things down it slows the speed moving through the air jacket allowing better transfer of heat. No idea if that's true or if I'm just making $hit up though.
That -is- crazy. It was cloudy and low/mid 30's here today and I didn't light a fire till about a couple hours ago when the house dropped to 68°! I let last nights 40lb fire die out, the blower shut off at 8:15am this morning..... Although my other half loaded a bit too much wood while I was gone on Friday so the house reached 78° at some point during the night, so the house temp was coasting down all day today.

You got the data logger now...try a few loads with blower on high...see what is shows when compared...My theory is when you slow things down it slows the speed moving through the air jacket allowing better transfer of heat. No idea if that's true or if I'm just making $hit up though.
My house has not been over 68 in like 2 months. Ill leave it on low though see what happensIt's not faster warm air though, it's faster/higher volume cooler air.

All that will tell me is what I already know.....I will have consistently lower supply temps throughout the burn and less blower run time at the end of the burn. The way I see it, if those real slow blower temps heated this place when it was -37° one night and with 4 or 5 days straight of 70 + HDD's (two with back to back 80+) it must be doing something right and I'm OK with that. Especially compared to what I was seeing the first winter. I don't necessarily need to know the "why".

I'm wondering if you really do have a very high heat load house. Like some have mentioned before, a home energy audit may be of some benefit to you. A blower door test may find some glaring issues which may be simple to fix.
mine would never work in -37 thats another reason why I bought the stove it never gets that cold here. I figured if they work in that im a sure deal but thats not what happen. Do you help it with other heat sources? or is that just the Kumma?All that will tell me is what I already know.....I will have consistently lower supply temps throughout the burn and less blower run time at the end of the burn.
