Home Fire Prest Logs produce heat for up to 12 hours. That is because of their patented technology compresses wood waste so densely that the logs will burn red hot throughout producing the most efficient burn available in manufactured firelogs today. The logs stay together without falling apart and have and extremely low moisture content of 2%.
The lack of moisture and the highly compressed wood fibers give such an even BTU output, some of their customers claim they need only 3 logs to heat their home all day! While this claim may seem exaggerated to some people, remember that conditions will vary with the efficiency of the wood stove and the area to be heated. Even their high users only use 12 log each day to heat their entire home. See More: http://www.homefirelogs.com/
