This year. NO sawing, NO spliting, NO stacking, NO large mess in the house. Skeptical, I tested and burned about a ton last year and was very happy. But these things have a cost right next to pellet fuel. Still good ol' wood is the way to go if you have the time to deal with it. But Bio's are freindly. I'll post some pics of new fisher stove and 4 ton pile later on.
