What are Electric Fireplace Inserts?

How to Choose An Electric Fireplace Insert?

It was once written: “A house with no fireplace is a house without a heart.” Does your home have a “heart”?  

    Perhaps your fireplace is old and needs updating, or maybe you don’t even have a fireplace at all but you always wanted one. 

    Wouldn’t it be comforting to know that there will be no clean up involved? Or that there would be no wood to chop or purchase?

    Enter electric fireplace inserts...

    Electric fireplace inserts are designed to fit into existing masonry fireplaces and convert them into clean energy efficient electric units. 

    Electric fireplace inserts come in three different forms: log set inserts, plug in fireboxes, and built-in fireboxes that need to be hardwired.

    Electric fireboxes can also be used in new construction and frame into a wall or cabinetry.

    Why You Should Choose Fireplace Inserts


    Did you know traditional wood burning fireplaces actually absorb warm air out of the room and into the fire?  The Hearth, Patio and Barbeque Association pegged older fireplaces’ efficiency at only about 5-10 percent.

    Electric fireplace inserts are designed to increase a fireplace’s efficiency up to 99%. So, not only is it an attractive addition to your home, it also reduces energy loss when heating your home.

    Air Quality

    Traditional fireplaces negatively impact your indoor air quality and our environment.

    There are many health implications that can come with burning wood indoors from allergies to asthma and all the way to cancer.

    Luckily we live in 21st century and have much safer alternatives.

    Electric inserts keep your indoor air clean and don't pollute our planet. Since there is no actual flames there are no dangerous emissions into the air. 

    If you have a health condition like asthma and always wanted a fireplace but couldn't - electric fireplace is a safe choice for you.

    Traditional fireplaces are hot and can be dangerous for little kids or pets.

    With electric fireplaces, you can be sure that your loved ones are safe. Electric fireplace inserts stay cool to the touch and won't burn little hands or curious noses. 

    There is also no danger of a spark getting out and starting a fire. With electric fireplaces there is no actual combustion, hence no fire hazard.


    Once installed, electric fireplace inserts are super easy to use and require zero maintenance. 

    You can control the flames and the heat with a touch of a button on the touch screen or remote control. Some models can even be connected to your smart home. We mention our favorite in the recommendations section.

    Easy to Install

    Electric fireplaces are easy to install. If you are getting a cordless log insert for your existing fireplace, this will be the easiest remodeling project you've ever done. All you'll have to do is charge the battery and insert the log set into your fireplace.

    Generally, installation of an electric fireplace insert is much easier than any other fireplace and can be DIY'ed or done by a general contractor.

    Of course if you are building out a brand new fireplace and inserting a fire box it will be a bigger project. Still, compared to any other types of fireplaces, installing electric insert will be much easier, faster and cheaper.

    Design and Style

    The thing about Electric Fireplace Inserts is that there are many looks and styles available. You can choose the insert to match your home’s overall design.

    For a sleek modern look, you can choose an insert with glass crystals and contemporary flame colors. For a more traditional look, you can choose the one with traditional logs and realistic flames. Or for a modern farmhouse a traditional insert with logs and clean concrete back is a great choice.

    Two Types of Electric Fireplace Inserts

    There are two type of electric inserts that can be used for reviving old fireplaces, electric log sets and electric fireboxes. Both of these types of inserts are vent-free, maintenance free, environmental friendly and safe to use around kids and pets. 

    Electric Log Sets

    Electric log sets recreate the glow of embers from a real fire with low energy LED lights, and do not require any installation at all. You simply place the log set inside of your existing fireplace and plug it into any standard household outlet.

    There are also cordless versions available. Keep reading, we'll talk about them in our recommendations section.  

    Electric Fireboxes

    Like log set inserts, electric fireboxes can also be inserted in existing fireplaces. What's different is that they can also be installed as new fireplaces and inserted into walls, mantels, or cabinetry.

    Electric fireboxes also use LED lights to create flame illusion. They also come with built-in heaters that can heat up 400 - 1000 sq ft. These heaters are silent and work independently from flames, so you can turn them off when you don't need them.

    Some electric fireboxes come with trim that you can use to frame the flame display and cover up the gaps if your firebox is a bit smaller than your old fireplace opening.

    Other models don't come with trim or you might find that the trim is not big enough to cover the gap. In his case you'll have to just have one made by your local contractor.

    Electric firebox inserts have a traditional fireplace shape but the flame display ranges from traditional to modern. You can choose to go with logs or contemporary glass to place in front of the flames and you can even change the flame colors for a unique experience.

    We love electric fireboxes for their finished look and realism. There are hundreds of options available. We handpicked some of the best ones for you in this article, so keep reading.

    How to Choose The Right Electric Insert?

    To make sure your new electric insert fits just right, follow these simple tips.

    Electric Insert Shopping Tips: 

    1. Decide whether you want a log set of a fire box
    2. Write down the dimensions of your existing fireplace or your new fireplace. Measure the height, width, and depth.
    3. When purchasing, find an insert as close to the height and width of your dimensions as possible.
    Bonus tip: Keep in mind that many masonry fireplaces get narrower towards the back. Once you pick your insert, double check the width of the firebox and make sure it still fits into your fireplace opening at the deepest part of that firebox.
