I know I have seen a comment about this in another thread, but I can not remember which one it was. Seems to me I remember someone in the boiler room saying that he does not, and you should not, put cold wood into your boiler/furnace. I tend to have a two or three day supply of wood in my basement, and rotate it as I bring it in. So the wood going into the wood boiler is at room temperature. My basement is always between 70-75 degrees. Even if the M.C. of our wood is at say 20%, there is moisture there. If it is 15 degrees outside, then that moisture is frozen. Does everyone keep the wood going into the boiler inside for a pre warm up? What do you guys do? And what do you think about this?
