The Eco Bricks still don't come near the birch in heat. Of course not loading the stove either and am just stickin my toes in the water 1 at a time
I can't quite explain this one...but my best effort is this. Ecobricks like friends. They prefer to be close to each other. If you spread them out and only burn one or two (maybe three depending on the size of your firebox) they won't burn as well as if they are right up against each other (more than that though, and you risk having a raging inferno as they manage to get temps up anyway even further apart). They feed off each other-fire likes heat. If you light a few sticks and place them at each side of the stove, they won't burn nearly as well as if you put them next to each other.
