Close Your Fireplace's Damper
Traditional fireplaces actually lose energy, since they pull warm air up the chimney and out of the house. When the fireplace isn't in use, make sure you close the damper -- but first ensure there aren't any smoldering embers lingering. If you decide not to use the fireplace at all, block the chimney off with a piece of rigid insulation that fits snugly into place. This type of insulation can be found at any hardware store.
