BioPellet said:Also, BioBricks(R) are very dense, 1.4 times denser than dry hardwood. When you speak of "burning hot" it's kind of hard to know what is ment, but let's assume we measure how hot things burn by running the test in open air. In fact, if you do this, you find the following trend from burning hottest to coolest:
Wadded newsprint -> kindling -> dry pine -> dry hardwood -> BioBricks. Density is your friend in that it promotes a slower release of energy
You are absolutely correct, but the danger is not how hot they burn, but the possibility of having a charge that is way too much. The high density allows you to easily over-pack your stove with fuel. I've seen some pretty badly overfired stoves from black locust, and I've hear of even worse with hedge. You should not stuff your stove with either of these woods if it has any tendency to run away on you, or if you are not very cautious about the amount of air that is coming in.
