I am splitting wood now in anticipation of my EKO 40's arrival, I feel like an expectant father getting the nursery ready. Anyway the wood I am splitting now I cut down in 2003, aside from some pieces that are getting eaten by bugs the wood looks great. Very dry! I am wondering what size is the limit for the diameter of log? For my wood stove I would split to about 7" on any one side maximum. If it was heart wood I would split larger as the heart wood tend to dry out better. For the wood boiler I am splitting as large as 10" on one side. My thought is the wood boiler has a much larger fire box and should be able to handle the larger diameter logs. Have you guys with wood gasifiers found any limits in this regard? I think EKO specifies 8" max, Zenon said no limit so long as it is dry.
