As you can see, this is "Alder" wood which is one of the best hardwoods as it doesn't do the sparking and little pitch explosions and burns nice and hot when seasoned. Our wood has been seasoned for a year bringing our consumption to a minimum as the wood not only burns hot, but burns slower. When you have unseasoned wood, the wood that is "green" doesn't burn hot or efficiently and you end up with a cold room, and using double what you would if it was seasoned. The ideal, is to season your wood for a year and then you will only consume half of what you would with green wood.
