first year in the house, 2700sf, fireplace xtrordinaire 36. used almost all weekends, and many weeknights after wee got home from work. we burned about 3 cords of mixed woods. about .75 cord i had split myself, and was mostly from 1 silver maple. the rest i bought, as "seasoned firewood" and turned out to be anything but that. lots of hissing, sizzling, and crackling, tough to get going, and tough to keep going. so now i decided to split as much as i can on my own...a little over a cord of oak from one tree so far, with probably another .5 to .75 cord to go from the same tree. probably will try to split a total of 3 for the winter
