Kiln-dried softwood logs, the moisture content in the logs is reduced to less than 20%, enabling the logs you burn to give out 3 times more heat. Burning wet or freshly chopped logs is in no way cost-effective and can inevitably lead to problems with your Log Burner, including the chimney clogging with tar making it very likely to stop working. Also, dried logs produce a lot less smoke. Suitable for Log and Coal fires, open stoves, fire pits etc.
