North Idaho Energy Logs are made entirely of wood by-products from sawmills, and are a much cleaner burning fuel than traditional firewood. The high density and low moisture content of our 8lb Energy Log enables it to pack 8600 BTU's per pound. With our manufacturing process our logs burn hotter and longer than firewood or other manufactured logs. North Idaho Energy Logs have been tested extensively against other manufactured wood heating logs. The 8lb Energy Log can not be compared one on one with the competition since other logs are lighter, at 2-6 lbs. Our tests have been done by weight. Pound for pound, the Energy Log burned twice as long as other manufactured logs. The log comparison tests were done in both a conventional uncertified wood stove and a phase 2 certified wood stove. Energy Logs consistently outperformed other manufactured logs. The high density and low moisture content of the Energy Log enabled it to pack 8,600 BTU's per pound. Amazingly, one 8 lb Energy Log has approx. 68,000 BTU's. Energy Logs are a compact bundle of energy just waiting to happen! Pound for pound it's awful hard to beat the price and efficiency of Energy Logs.
