Quality firewood will help your wood stove burn cleaner and more efficiently. Green and wet wood can cause smoking problems, odor problems, and rapid creosote buildup.
Freshly cut firewood contains 45% water, while well-seasoned firewood generally contains about 20%-25%. Seasoned firewood produces more heat, and is easier to start. If your wood is cut six months to a year in advance and stored correctly, the sun and wind will naturally season it for you. If you burn green wood, the heat produced by combustion must dry the wood before it burns, using up most of the energy in the process.
Bad storage can ruin even well-seasoned firewood. If exposed to constant rain or snow, it will reabsorb large amounts of water making it unable to be burned. It is best if the wood is stored off the floor and away from moisture when weather threatens.
