The first question you'll need to consider is whether this is a project you can do on your own or if you'll need to hire a professional to install your electric fireplace. If you've got a solid set of carpentry and DIY skills, it's likely you can do most, if not all, of the installation yourself. The main complicating factor is the fireplace's electrical supply. If the fireplace uses a simple wall plug and your fireplace opening has an outlet in it (or near enough) already, then it's as simple as plugging it in. However, many electric fireplace insert models require hardwiring to your home's electric system. In that case, we recommend working with a licensed electrician to complete the installation.

To ensure your new fireplace looks great and operates safely, you'll need to follow the manufacturer's recommended clearances, which you'll find listed in the owner's manual. These measurements tell you how much space should be left clear between the fireplace and the opening you're placing it in. Generally speaking, these clearances will be somewhere between ¼"""" and 3"""".

For best results, we recommend purchasing a fireplace that is as large as possible while respecting these clearances. This will ensure that your new electric fireplace insert will look impressive and natural. Many models will either include or can be upgraded with a trim kit that can help bridge the gap between the edges of the insert and the edges of the fireplace opening, ensuring a polished look. Check out the specific product details on any model you're considering for more info.

A 120-Volt electric fireplace insert will draw about 1,500 watts at 12.5 amps. This will include all plug-style electric fireplaces. If you choose a larger, hardwired fireplace, it will likely be a 240-Volt model that draws 2,800 watts at about 12 amps. The exact details for each fireplace model may vary a bit, so we always recommend checking the owner's manuals you can find on our website for whichever fireplace you're thinking of buying.

Take accurate measurements of the firebox before purchase:

To ensure you buy the right size of electric fireplace, you'll need accurate measurements of the firebox. Measure the height, depth, front width and back width to determine how large of an electric fireplace insert you need.

Inspect the chimney and fireplace opening before installation:

While electric fireplaces don't require ventilation, an electric fireplace insert is generally installed in an existing fireplace, which means there will be a masonry firebox and chimney in place. It's a good idea to place a cover plate on your chimney to keep water out and close and seal the damper to prevent drafts when installing an electric fireplace insert.

Use a trim kit to complete the installation:

Many electric fireplace inserts can be upgraded with a trim kit that makes it easy to provide a polished-looking front. While shopping for a new fireplace insert, be sure to consider whether you're interested in adding a trim kit and check whether one is available.
