Electric fireplace dimensions. A wall mounted electric fireplace is the best solution for creating a bold style statement in your home office or simply saving space in a small room. Electric inserts can be fitted into just about any existing fireplace. Fluted columns on either side of the firebox provide a unique element of design to the mantel and an understated molding adds a classic touch to this electric fireplace.
The dimensions of the insert must fit within the fireplace cavity.
