Although no heating appliance can be entirely risk-free, a fireplace insert is considered a safer alternative to a traditional open fireplace, thanks to their enclosed design. With a sealed combustion chamber, a fireplace insert effectively reduces the risk of sparks and embers escaping into the room, minimizing the chance of an accidental fire.

Additionally, an insert comes equipped with various safety features, such as tempered glass doors that create a barrier between the flames and the surrounding space. This enhances both safety and energy efficiency by preventing heat loss. As an added bonus, many inserts are designed to meet strict safety standards that ensure proper ventilation and combustion.

The damper, located just above the firebox, can open or close the chimney flue. The damper should remain closed unless there’s a fire burning in the fireplace. Closing the damper prevents energy loss through the chimney and cold air from seeping into the home during the winter. Opening the damper helps maintain airflow when there is a fire and prevents smoke and gases from venting into the house.
