For a less permanent solution compared to built-in electric fireplaces, electric fireplaces can also be used as inserts into existing open fireplaces.
Electric fireplaces inserts fit directly into an existing open fireplace and a surround can be used to fill any gap between the unit and the edge of the fireplace to make it look more built-in.
These fireplace inserts are typically plug-in and so you may need to have an electrical outlet installed within the firebox of your open fireplace.
