What is a fireplace insert

Fireplace insert is a device used in interiors to ensure not only thermal comfort but also a pleasant atmosphere. The fireplace insert, unlike the traditional fireplace, does not have an open fireplace. Otherwise, both devices have a lot in common. They use the same wood, briquettes or biomass, and must be connected to the chimney. Fireplace inserts are often made of steel or cast iron, but types of chamotte or verticular bolsters can also be made today, or combinations of these materials are used.
