How does a fireplace insert work?
Insert Installed In Fireplace A fireplace insert is actually placed inside an existing fireplace. Old models were simply set in the fireplace without being connected to the chimney, which caused some lighting and smoke problems. Newer models include piping that runs the length of the existing chimney, connecting the insert directly to the outdoors.This provides proper air flow and increases the safety by reducing places where ash and creosote can collect. Air Forced Into Room The primary reason most fireplace inserts are installed is to increase efficiency. Fireplace inserts do this in two main ways: by forcing heat into the room rather than letting it be absorbed into the masonry or the chimney, and by increasing temperature while reducing the combustion rate. The increased temperature and lower combustion rate means that less fuel creates more heat. Heat is forced into the room mainly through strategically placed vents and fans. Temperature Control Many fireplace inserts include auto
