I have been using my Hawkins stove for 4-years now....I have heard many ideas on loading the stove here is what I have found works best for me.....I split my wood into manageable size pieces....I like to be able to pack my stove full when it’s teally cold like when it’s 5-degrees or lower....big pieces are fine and dandy, but I can pack more in when the wood is split....
I also burn different types of wood depending on the temperature....when it’s over 20-degrees I burn softer stuff maple, walnut, and some ash....when it’s 10-degrees it lower I start getting to the oak, hickory, and Osage.....I also load my stove 2-times a day, when it’s in the negatives I may check it 3-times just to be safe....I Always get paranoid when it’s that cold, I have a 2-1/2 year old little girl and a pregnant wife so they are #1 priority always!!!!
