What is a fireplace insert?
An insert is a heating appliance, technically a stove (although it cannot be used for cooking), that gets inserted into an existing fireplace or a new structure built to contain it. Inserts are available for all fuel types (gas, electric and wood), although the widest selection is in gas. Gas and wood inserts require appropriate venting via a natural chimney vent or a direct-venting system. Inserts with a glass front are efficient because they are completely enclosed, thus preventing drafts. They work by pulling fresh air into their venting system from outside, and then venting fumes back outside, preventing indoor pollution. Vent-less gas inserts can be even more efficient, provided you have the appropriate requirements for this type of unit.
Fireplace inserts are heating units that retrofit into an existing fireplace (masonry or factory-built). They burn wood, gas or wood pellets and offer superior efficiency. Fireplace inserts utilize the existing chimney, though a flue liner or other modification may be necessary. Vent-free fireplace inserts require no chimney or flue modification. Most have blowers to circulate the heat. Inserts are used to change an existing non-efficient fireplace into an efficient, heat producing zone heat.
