Conundrum About Coaling?

I need to get some sort of small rake to bring coals to the front of my stove. I get a lot of coals when it drops well below zero out and as said it makes sense that I keep feeding the fore with more wood took maintain my indoor temperature while never really letting the coals burns down. Maybe I should get a bigger stove for the next one...? This one is a 2.2cf heating a 3200 sq ft home with 20' cathedral ceiling. But the home is very tight and super insulated.... I know it since I built it myself and I had a blower door test to confirm it.

 

Same wood from the same pile of mixed species or same wood from the same tree? If it is the former you will certainly see differences in coaling between species of wood. A chunk of oak will still be a big piece of charcoal in the same period of time that a piece of silver maple will be reduced to fine ash. Is it in part that the mix you are burning has changed?

 

With that size house being well insulated I'd go with a BKK, the belly so big you can go a long time without worrying about coals.

 

Wow! I really want to thank everybody for the input!
It looks like I am doing everything right, and maybe overthinking the coal(charcoal) a bit. I knew with damp wood that would happen, but this started after the stove was tightened up, and I know my wood, which is almost exclusively oak, was dry. I stacked in summer on 2012, with strips of tarp covering the tops only. I have no soot inside the stove or on the glass, but there is an occasional white film that I like to wipe off.
So I am thinking that because I am a night and weekend burner, I am noticing it more than usual; the few times I have been home a few days, I just keep it going; like what Backwoods and Certified said, if I open it up a little more at night, it should burn down better. I am always worried about sucking the warm air from the house, as the stove will not be fired up again until the next evening when I get home.
Now--Wildwest, I double checked all the windows, no prob. BUT--I found that the shoddy door gasket job had indeed left the top portion loose! I think that when I close it, it was not really staying in the groove. I took some silicone and put a bead along the channel and re-attached it. It did seem tighter, but the dollar bill test still failed on that portion. I think I will order a PE gasket from Tom at ChimneySweeps and do this myself from now on.
Again, I want to thank everyone who helped! Rocky, did leaving it open last night help? Also, what I use is one of those ash rakes(got mine on Amazon), and this forked gizmo that is a blowpipe on the other end. I push everything to the back with the hoe, then tease all the coals to the front with the fork thing.
Unfortunately, the item is no longer available on Amazon, but this is what I got:
