Kiln Dried Logs burn hotter than Seasoned Logs. A kiln dried log has a lower moisture content, meaning less energy is required to burn off moisture, resulting in more energy being converted to heat.  The higher temperatures generated by kiln dried logs mean that everything is burnt, even the gasses released by the wood. In a cooler fire these would simply escape up the chimney. Kiln Dried Logs are also more economical; because they burn hotter and more efficiently, you use less logs to achieve the same heat output.   Kiln Dried Logs help to increase the life of your stove – the higher temperatures burn off the water and sap remaining in the wood, stopping it from building up on the inside of your appliance as tar, which over time, can clog and rust your stove leading to a loss of efficiency.
