What To Consider When Buying An Electric Fireplace Insert For Your Existing Fireplace

When buying an electric fireplace insert to fit inside your existing traditional open fireplace you’ll want to look for a plug-in electric fireplace insert.

Plug-in inserts simply need to be plugged into a standard home electrical outlet in order to work.

There are also other types of electric fireplace insert, but have different purposes. These other types of insert include:

  • Built-in electric fireplace inserts
  • Electric fireplace log sets

Built-in inserts can also be used inside existing open fireplaces but are more suited to installation within walls or homemade entertainment centers. They typically need to be hard wired into your electric and are a more of a permanent solution that plug-in inserts for a traditional open fireplace.

Log sets are simply the logs, grates and embers by themselves without the complete unit surrounding it. Logs sets are therefore the easiest way to turn your traditional wood fireplace into an electric one, but aren’t able to transform your whole fireplace like the other forms of inserts can.

Read our buyers guide to the best electric fireplace log sets here.

When buying a plug-in electric fireplace insert for your existing fireplace you’ll need to consider the following:

  • Size of your existing fireplace and therefore best size of insert.
  • Trim to make the insert look fitted.
  • Flame effects.
  • Heater.
  • Providing power to the insert.

Size of Existing Fireplace

When choosing which brand and model of plug-in insert to install in your open wood fireplace, you’ll need to consider what size of insert (in inches) best fits.

You’ll want to buy an insert that is the right fit or smaller than the dimensions of your existing fireplace opening. You don’t want to get an insert that is too large or you’ll need to make structural changes to your fireplace.

Insert sizes are defined in inches for the width. For example, a 27-inch insert will be approximately 27-inches wide.

You’ll also need to check that the height and depth also works with your fireplace, and that you’re leaving a sufficient gap between the back of the insert and the back of your fireplace firebox.

Flames

All electric fireplaces will produce realistic flame effects, but some offer more life-like features than others.

The flame effects and choice of settings such as flame speed, brightness and color will differ between the different brands, and so it’s down to your preference which effects you like the look of the most.

Some inserts also allow you to choose between acrylic ice and logs for your ember bed when ordering.

Heat

Inserts with conventional fan heaters will be able to heat up to 400sqft of area in your home when plugged into a standard electrical outlet, or some can be direct wired into your electrics to be able to heat up to 800sqft of space.

Some inserts include ceramic or infrared heaters rather than fan heaters, and are much more powerful allowing you to heat rooms in your home up to 1000sqft.

Power

With plug-in electric fireplace inserts you need to plug them into an electrical outlet in your home in order for them to work.

If you don’t already have an outlet inside your fireplace then you’ll need to get one installed.

Some plug-in inserts also provide the ability to direct wire the unit into your electrics.

Other Features

The majority of plug-in inserts come with a remote, allowing you to use all of the features of the fireplace from your seat.

Many will have also thermostats allowing you to keep your room at a constant temperature.

What Is An Electric Fireplace Insert?

An electric fireplace insert is placed inside an existing fireplace, wall, mantel or entertainment center to provide the experience of having a real fire without many of the downsides.

The main forms of insert include linear, plug-in, direct wired and log sets.

What Size Electric Fireplace Insert Do I Need?

For an existing fireplace, an insert must be smaller than the opening of the fireplace, but large enough so that a trim can be used to make the insert look fitted.

What Is The Best Electric Fireplace Insert For Heat?

Inserts that use ceramic or infrared heaters will be able to provide the most amount of heat, typically being able to heat areas up to 1000sqft.

Fireplace inserts that have conventional fan heaters will typically only be able to heat spaces up to 400sqft.
