My wood has to be trimmed down from 25 inches or so, to about 18 for the new stove. The ends are anywhere from 1-6 inches when cut away. I would have guessed that a full stove of ends would be a risky load likely to cause a runaway burn. This is not the case at all. A full load with primary air wide open burns very slowly. I am guessing that is due to the lack of continuous air paths for the fire to spread through. I had to add a couple splits onto this mornings load to get the stove up to a temperature that would offset the 35 degree overnight effects. These loads of ends burn consistenly, just slowly. A nice ability to have. We are supposed to see upper 50s this weekend, so there will be lots of chunks loaded for the next few days.
