    Close the flue - look inside of the fireplace and pull the lever connected to the flue at the top of the chimney, only if you do not use it.

    close the flue, and insert a a chimney baloon. There is a string on the balloon to remind you it’s there. It makes a tighter seal so cold air can’t get in.’s the law. Hot air rises, cold air sinks.

    If you are not using, close the flue. If it is rusted out or nonexistent (old ones can rust and fall out), and you have glass doors, roll up old towels (obviously remove them if you use the fireplace) and place them at the bottom to block air. Use clear tape to cover the cracks in the glass doors. If you have no doors and this is a real problem, and how it looks does not matter (as in the east we are experiencing frigid cold). Get a large piece of plywood and block the fireplace hole. There is also a commercial product that is large Styrofoam that fits in the hole to block the chimney.
