9 Things To Consider When Choosing An Electric Fireplace

Last reviewed: September 15, 2026

Choosing an electric fireplace comes down to a handful of practical decisions — placement, power, heat output, and design — more than any single "best" model. This guide walks through the factors that actually change which fireplace is right for your space.

1. Placement

Since electric fireplaces don't need venting, they can go almost anywhere in your home — the deciding factor is really which room and spot gets the most use. An electric fireplace insert drops into an existing fireplace opening. A wall-mounted model works well when floor space is tight, including slim options that barely protrude from the wall. For a more permanent, flush look, compare built-in electric fireplaces. Whatever you choose, keep the unit clear of furniture or objects that could block the heater's inlet or outlet.

2. Your electrical setup

Most electric fireplaces run on a standard household outlet, but that outlet needs its own dedicated circuit breaker — don't run one on an extension cord. Check what's available in the room you're planning for; larger or built-in installations may need an electrician. See our electrical requirements guide for specifics.

3. Heat output

Heat output is measured in BTUs (British Thermal Units) — the higher the rating, the more heat the unit produces. Most electric fireplaces run around 5,000 BTUs, though output varies by model; check our room-by-room heating guide to match BTUs to your space. If you only want the visual effect, many models let you run the flame without heat.

4. How you'll actually use it

Electric fireplaces won't work in a power outage, which matters if you're weighing them against a wood or gas option for that reason. Decide early whether you want the fireplace purely as a design feature or as genuine supplemental heat — that decision shapes which models are worth comparing.

5. Design

Electric fireplaces come in a wide range of shapes and styles, so matching one to your home's look is rarely the hard part. Depending on the effect you want, compare water vapor fireplaces for a more three-dimensional flame, outdoor-rated models for a covered patio, or traditional built-in and wall-mounted styles.

6. Installation

Freestanding units need no installation. Wall-mounted models are often a DIY-friendly afternoon project. Built-in fireplaces are the most involved, typically requiring framing and sometimes an electrician — see our installation cost guide for what to budget.

7. TV placement

If you want a TV above the fireplace, look for a front-venting model, or budget more clearance if the unit vents from the top. A fireplace suite with a built-in mantel is another route to a finished look.

8. Flame effects

Most units use LED lights and mirrors to create the flame; some add rotating elements for more natural movement. Flame color and brightness customization varies significantly by model, so if realism matters to you, compare a few in person or via video before deciding.

9. Warranty

Check the manufacturer's warranty before buying — most run one to a few years, and terms vary by brand. Electric fireplaces generally need little maintenance, but a warranty is still worth confirming for peace of mind.

Common mistakes

The first mistake is choosing a fireplace before confirming the room's electrical setup, which can mean an unplanned electrician visit. The second is picking heat output based on the fireplace's size rather than the room's actual square footage.

Frequently asked questions

Can I install an electric fireplace myself?

Often yes, for freestanding and many wall-mounted models. Built-in installations more often benefit from professional help, especially if framing or electrical work is involved.

Do all electric fireplaces need a dedicated circuit?

Many do, especially larger models. Confirm the specific product's electrical requirements before buying, and check with an electrician if you're unsure about your home's wiring.

What's the average heat output of an electric fireplace?

Most models produce around 5,000 BTUs, though output varies. Compare BTU rating to your room size using our heating guide.

Will an electric fireplace work during a power outage?

No. Electric fireplaces require power to run both the flame effect and the heater.

How long do electric fireplace warranties typically last?

Commonly one to a few years, though this varies by brand and model — always confirm before purchasing.
