My second year for splitting wood and have accumulated quite a few "ugly" hunks. (Not enough to justify renting a splitter). At first I tried to split them to a reasonable size - but because of knots or type of wood or whatever, they got the best of me. So now, I have a pretty good size pile and am wondering how well they will burn. Some/most pieces will fill my entire stove and it's a mixture of various wood. Do I use them like any other split or are there some things I should know? Stove is a Hearthstone Homestead. Maybe there is a way to use chainsaw to reduce their size - but it's also only my second year for cutting wood and I haven't come across that yet - so maybe you have some help there also.
