What is an insert for a fireplace?
Just so, what the difference between a fireplace and an insert?
Either way the fireplace is the entire structure that you burn inside of. A fireplace insert is basically a stove, wood or gas, that is designed to be inserted into a fireplace that is already there. Usually a wood burning fireplace built with the home will get an “insert” put inside of it.
In this regard, how does fireplace insert work?
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.
A fireplace insert can be an alternative to your traditional fireplace. It is a wood or gas stove that has been modified by the manufacturer, which is used to convert a masonry fireplace into something more efficient.
