Because these "BioBricks" can be tightly packed, the fire burns longer and more uniform. A ton of BioBricks, when burned, will give as much heat as a cord of seasoned firewood. Our BioBricks are free of the dust, dirt, bugs, vermin, and the mess that is commonly associated with burning cordwood.
They are the perfect size; if bigger they might not burn up completely, if smaller they might burn too hot.
Start burning with care to not overload your stove. If this is your first time burning the bricks start with only 4 or 5 to see how your stove reacts. Remember that these are very dry and dense bricks and therefore they contain alot more BTU's per cubic inch than cordwood. Full full instructions go to http://originalbiobricks.com/howtoburn.
