Types of Electric Fireplace Inserts

First, you need to choose the type of electric fireplace insert that will fit best in your fireplace. This will depend on the aesthetics you are looking for and the space you have available. The three main types of inserts are electric log sets, built-in, and plug-in.

Electric log fireplace inserts are little sets of faux logs. They are designed to be as realistic as possible and sit on a set of legs, to look like a fire in a trough. They slot into your fireplace and plug into a standard 110v outlet. The logs give off radiant heat, with some including a fan to circulate this heat.

If you’re installing your insert into a mantlepiece or a cupboard, you'll want a plug-in electric insert. These fireplaces look like enclosed fires with a glass front, and they slot into your existing feature and plug into a standard socket. You will find radiant and infrared versions of this model.

If you're in the process of upgrading the whole fireplace and mantlepiece, you may consider a built-in electric fireplace insert. They are installed using a builder’s box and are more of a permanent feature.

They can be hardwired or plugged into a regular socket. But require a little more installation skills than the other two models.

Choosing Electric Fireplace Inserts

Heat Capacity

When selecting a heater you must consider the size of the space you intend to heat. Measure your room first and consider the BTU output of the heater. If you get a heater with too much power, you’ll waste energy. Something too small simply won't do the job.

Safety Features

If you have small children or pets, then the safety features of your heater are likely to be a big concern. You want to look for an insert that is cool to touch just in case a pet or child gets their hands on it. Those with glass fronts tend to be cooler.

You might also consider looking to overheat protection to reduce fire risks in the household. Remote controls should have child locks to help prevent the heater from being turned on accidentally.


If you are installing the heater by yourself, you may need something that doesn’t require much vocational skill. However, if you’re reconfiguring the whole look of your space, you may want to install something more complex to improve styling.

If you want a more grandiose electric fireplace insert installed but don’t have the skills yourself, you may have to pay someone to install your fireplace professionally.


The overall style that you are trying to achieve will determine the fireplace that you choose. If you are happy with the log effect, you’ll find it easy-to-install. Whereas the enclosed fire style needs more skill. Moreover, look at the wood effects, colors, and trims to see how neatly it will complement your existing furnishing.


Upfront pricing will always give you a realistic understanding of what you can place in your home. Also remember to consider the cost of running the heater. Look at reviews from other customers and remember to select a fireplace that can cope with your heating requirements.
