The Best Electric Fireplace Inserts

A fireplace insert changes how a room feels. It turns a dead masonry firebox, an unused den, or a finished basement wall into a focal point without cutting a gas line, storing firewood, or booking a chimney sweep.

Modern electric models deliver convincing flame effects, optional crackling audio, and genuinely usable supplemental heat, which is why they keep showing up in living rooms, bedrooms, and converted garages.

If you already lean on space heaters for spot warmth, an insert does much the same job while giving the room something worth looking at.

This guide reflects the shortlist our editors would build after weighing published specifications, expert review consensus, verified buyer feedback, and manufacturer data.

We compare opening dimensions, heater output, flame realism, control options, noise, and the reliability signals that repeat across owner comments, so you can match an insert to a real firebox instead of a marketing photo.

Where running costs matter, it also helps to read up on energy-efficient space heaters so you know what a 1,500 watt appliance can and cannot do for a room.

Below are the picks we would put in our own homes, ordered by how well they balance those priorities.

The 3 Best Electric Fireplace Inserts on Our Shortlist (November 2026)

Best Electric Fireplace Insert Buying Guide

Start With the Firebox Opening, Not the Flame Video

Almost every disappointed insert purchase traces back to a dimension mismatch.

Measure the width and height of the opening at the face, then measure the depth to the back wall and the interior width at the rear if the box tapers.

Insert makers publish a minimum opening figure, and the surround trim is designed to overlap the masonry so the finished look stays clean.

A model listed at roughly 33 inches wide, such as the PuraFlame Western, is sized for a common masonry opening, while a 23 or 26 inch unit suits a bedroom or a smaller prefab box.

If there is no firebox at all, you are really shopping for a recessed or wall mounted unit instead, and the constraint shifts to stud spacing and depth inside the wall cavity.

Some 60 inch models are built to fit a 2 x 6 stud bay, which is a meaningful detail if you are framing new construction.

Sunrooms, three season rooms, and porches are another common home for a log set that simply drops into an existing opening, and the same measuring discipline applies to space heaters for enclosed porches.

Heater Output, Wattage, and Square Footage

A 1,500 watt heater produces roughly 5,100 BTU, and the 750 watt setting delivers about half of that.

That is supplemental heat, not a furnace replacement, so treat the fireplace as a way to take the chill off one room rather than a whole floor.

Most units run on a standard 120 volt household circuit, and sharing that circuit with a vacuum, a space heater, or a kettle is the fastest route to a tripped breaker.

Insulation, ceiling height, and window area decide how far that heat actually travels. In a tight, well sealed living room, a mid-sized insert can hold its own on a cold evening.

In a large open plan space, output matters far less than the flame package, and if heat is the real priority you should compare against space heaters for large rooms before committing to a decorative unit.

Thermostatic control is the feature worth paying attention to.

A unit that cycles the heater on and off around a set temperature feels far more comfortable than one that simply blows hot air until you switch it off, and it keeps the blower from running constantly in a small room.

Flame Realism, Ember Beds, and Sound

Flame technology has improved dramatically.

LED and mirrored ember bed designs now produce dancing flames with adjustable color, brightness, and speed, and higher end models offer dozens of color combinations along with interchangeable media such as faux logs, crystals, and driftwood.

The difference between a convincing fire and a glowing orange screen usually comes down to depth: a recessed unit with a reflective back wall reads as flame, while a shallow surface mount can look flat from an angle.

Crackling sound is a small feature that changes how often people actually use the fireplace. Look for adjustable volume, because a fixed crackle gets tiresome in a bedroom.

If the insert sits in a room where you sleep or work, noise from the blower matters just as much as the audio track, and the same low level hum concern applies to quiet ceiling fans for sleeping.

Controls, Remotes, and Smart Home Integration

At minimum you want a remote, a timer, and a touch panel that stays readable in a dim room.

A 24 hour programmable timer is genuinely useful for a basement or a rental property, and a remote means you are not crouching on the hearth every time you want to dim the flames.

Flame color and heater output should be controllable independently, so you can enjoy the fire in July without the heat.

WiFi models that work with Alexa and Google Home move the fireplace into the same routines as the rest of the room.

That matters more than it sounds: scheduling the flames for the evening and the heater for the morning turns a decorative appliance into something you actually live with.

If you are already building those routines around smart ceiling fans, look for a fireplace that speaks the same protocol.

Installation, Clearance, and Electrical Load

Plug-in inserts are the easiest path, since the cord simply reaches an outlet and the unit vents into the room. Hardwired and recessed builds look cleaner but need a dedicated circuit and, in some cases, a licensed electrician.

Wall mounted units require solid anchoring into studs, and the manufacturer clearance figures around the top and sides are not suggestions. Keep the front of the fireplace clear of curtains, stockings, and furniture, and never block the blower intake.

Garages, workshops, and outbuildings are a different job entirely, because dust, drafts, and cold surfaces change how a heater behaves.

If the space is unheated for most of the year, it is worth comparing the fireplace against propane garage heaters that are built for that environment rather than pushing a decorative insert past its intended use.

Noise, Air Quality, and Everyday Comfort

In flame only mode most inserts are silent, and the blower is the only thing you hear once heat is on.

Blower noise varies a lot between models, so check owner comments for words like whine, rattle, or hum before you buy a unit destined for a bedroom or a home office.

A low fan speed setting is often enough for a small room and is noticeably quieter than high.

An electric fireplace does not add moisture and it does not remove it, but the air movement can stir up dust that settled around the hearth, and warm dry air tends to feel drier in winter regardless.

A quick pass with one of the HEPA vacuum cleaners around the surround keeps ash free surfaces actually clean.

Wipe the glass front with a microfiber cloth and a non-ammonia cleaner, and dust the media tray a few times a season.

Why You Should Trust Us

AirpurifierTop Review scores every product on a 0 to 10 APT Score using a consistent set of criteria applied across the whole category: fit and dimensions, heater output and control, flame realism, build quality signals, noise, ease of installation, and long term owner satisfaction.

We do not conduct our own product trials; our evaluations are grounded in research, published data, expert review consensus, and verified buyer feedback.

That means we read specification sheets line by line, compare manufacturer dimensions against the openings real buyers describe, and weight the complaints that show up again and again rather than the ones that appear once.

Where a category overlaps with another heating product, such as heat pumps or gas fired patio units, we cross check efficiency claims so a fireplace is never presented as something it is not.

AirpurifierTop Review is independent and reader supported. We do not sell products, we do not handle orders, returns, or warranty claims, and a brand cannot pay for a spot on this list.

If a product earns a recommendation, it is because the research and the owner record support it.

Final Thoughts

The right insert is the one that fits your opening, matches how you will actually use the room, and does not promise more heat than a 120 volt circuit can deliver. These five stand out for different reasons.

• Best Overall: Touchstone 80004 Sideline In-Wall Recessed Electric Fireplace carries one of the highest APT Scores in this guide thanks to a flush recessed profile, three flame color sets, and the kind of steady build quality owners keep mentioning after a year of use.
• Best for an Existing Firebox: PuraFlame Western Electric Fireplace Insert is sized for a standard masonry opening and adds crackling sound plus a remote, which is exactly what most people want from a drop-in replacement.
• Best Smart Option: Touchstone Sideline Elite Smart 60 inch WiFi-Enabled Electric Fireplace pairs the widest color range here with app and voice control, a strong fit for a main living wall.
• Best Budget Pick: EUHOMY 50 Inch Electric Fireplace Recessed and Wall Mounted scores close to the leaders at a budget friendly price, which makes it the sensible entry point for a first fireplace project.
• Best Small-Space Insert: 23 inch Electric Fireplace Insert by Innoflame fits tighter openings, runs quietly, and includes the timer and overheat protection you want in a bedroom or den.

If your plans extend to a deck or a covered patio, the same logic applies outdoors, and natural gas patio heaters are the category to study before you buy.

Frequently Asked Questions

Do electric fireplace inserts really produce heat?

Yes, most include a fan forced heater rated at 750 or 1,500 watts, which is enough to warm a single room on a cool evening. The flames themselves generate almost no heat, so the blower does the work.

Treat it as supplemental warmth for the space you are sitting in rather than a replacement for a furnace.

Can I put an electric insert into an existing wood-burning fireplace?

In most cases yes, and it is one of the simplest ways to keep a chimney out of service without losing the focal point.

Measure the opening, confirm the depth clears the insert body, and make sure an outlet is reachable or that a circuit can be added.

Have the chimney capped and cleaned first if it has been used for solid fuel, since soot and creosote residue will smell once the room warms up.

How much does it cost to run an electric fireplace insert?

Running cost depends on your electricity rate and how long the heater stays on, since a 1,500 watt element draws about as much as a portable space heater.

Flame only mode uses a small fraction of that because the heater is switched off.

A thermostat and a timer are the two features that keep the bill predictable, and using the low heat setting in a small room is usually enough.

What size insert do I need for my firebox?

Measure the opening width and height at the face, the width at the rear, and the depth to the back wall. Then compare those numbers against the manufacturer minimum opening, not the outer trim size.

Leave a little breathing room on each side, and check that the cord and plug do not push the unit forward out of the surround.

Do electric fireplaces dry out the air?

They do not remove moisture the way a combustion appliance can, but warm air holds more moisture and a sealed winter room often feels dry regardless of the heat source.

If static shocks and dry throats become routine, whole house humidifiers address the cause rather than the symptom.

Is an electric insert a good choice for a cold climate bedroom?

It works well as a supplemental source in a room that is already heated, and the flame only mode is a comfortable night light with no heat.

In a genuinely cold room, pair it with a proper cold climate system such as mini splits with heat pumps rather than expecting 1,500 watts to carry the load.

If air quality is also a concern, a unit like a Dyson Hot and Cool air purifier handles filtration and fan circulation separately.
