I used to have a wood stove. The wood I liked to burn, because it burned hot and slow, was eucalyptus, ironwood, oak, and almond. These are hard woods. Pine burns hot and fast. It is a soft wood. I would use small sticks of pine and news paper to start my fires. After the fire was started, I would increase the size of the pine until the fire became hot enough for the harder wood. I would move the lever of the flue from all the way open to the middle, so the flue was half open and half closed. The flue on a wood stove allows a little or a lot of air flow to fuel the fire. This way the log would burn for an hour or two given the size of the log. Green wood smokes and is used for signal fires in the open. Green wood won't work good in a wood stove or fire place, it'll just create a lot of smoke. Seasoned means the wood has had time to dry properly and is good to go. In a fire place I would use the same method. A wood stove will heat up a whole house given the size of the house compared to the size of the stove. A fireplace is open and is not as insulated as a wood stove so more heat goes up instead of out. The fireplace will heat up the surrounding area the hottest leaving the rest of the house much cooler. Buying the wood can be a challenge because the harder woods are more expensive than the soft woods. Buying a mixed cord of soft/hard wood is a good idea. Soft wood burns hot and fast. Hard wood burns hot and slow. Keep that in mind when creating a fire. I hope this helps.
