An open fireplace pulls warm room air up the chimney along with the smoke, and can leave a house colder overall. An insert is a stove that sits inside the fireplace opening, with a sealed door and a liner up the chimney, so the heat comes into the room instead. Check the insert’s firebox dimensions against your fireplace before buying, and have it installed with a full chimney liner where the manual calls for one.
