Do you have an unused wood-burning fireplace that you’d like to convert from a ‘black hole’ to a warm and inviting fireplace again?  Electric inserts are quick and easy to install, and — best of all — they’re inexpensive.  Most also provide heat. 

Here’s what you need to do to convert your fireplace:

  1. Measure your fireplace opening at the front, as well as 9” and 12” into the opening.  You will need to know the width and height of the fire opening at these 3 points; this will cover all the options for inserts.
  2. Review the insert options currently available, to see which flames you like, as well as which size fits your opening.  An insert designed for retrofitting into an existing opening will not have a glass frame around it; it will slide into the opening, allowing you to use your existing fire screen or doors.  Other fireboxes or inserts, with glass fronts and metal frames around them, must fit your opening exactly, in order to avoid gaps around the firebox.
  3. Get a 120 volt electrical outlet brought into the fireplace opening.  This is usually done by pulling a line from an adjacent outlet in the same room, or by pulling a new line from the electrical panel, usually through the floor of the fireplace if the space below the fireplace is unfinished.


Now, just close the flue and plug in your new insert, and – Voila! – you can enjoy the ambience of a working fireplace once again.
