Fireplace Inserts, Wood, Gas and Pellet Insert

Fireplace inserts are designed to increase a fireplace's efficiency. An insert is basically a fireproof box that's surrounded by steel or cast iron and fronted by insulated glass, creating a closed combustion system. The steel or cast iron helps to trap the heat. Some inserts have a blower that pushes the hot air back into the room through front vents. Properly installed, fireplace inserts can be a much more efficient supplemental zone heater than a traditional fireplace.
