An unused wood-burning opening can become a clean, controllable source of atmosphere and supplemental warmth. The best electric fireplace inserts for existing fireplaces are not automatically the biggest models; the right answer starts with the opening width, height, depth, and the kind of installation you want.
Yes, you can put an electric insert in an existing fireplace when the unit fits the opening and its clearance and electrical instructions are followed. It creates flame effects with LEDs and internal optics, while a heating element and fan provide heat, so it needs no chimney or combustion venting.
I separated true-looking log-set choices that can sit in a hearth from wide recessed models that need a prepared wall or surround. For a broader category view before measuring, see our comprehensive guide to the best electric fireplaces.
The Top 3 Electric Fireplace Inserts Answer three Common Needs (August 2026)
The EUHOMY is my wide, shallow recessed choice because it is only 4.3 inches deep and pairs a 60-inch presentation with dual heat modes. The Touchstone Fireplug is the direct choice for a 31-inch-wide masonry opening with Alexa, Google Home, app control, and built-in crackle sound.
For people who want to place a unit inside an existing firebox without building a recess, the PuraFlame 27-inch log set offers the clearest starting point. It is a freestanding unit designed to be placed and plugged in, with adjustable flame, thermostat, timer, and sound features.

1. The best wide shallow choice is the EUHOMY 60-Inch Recessed Fireplace
Pros
- Very shallow profile
- 144 color combinations
- log and crystal sets
- 1 to 8 hour timer
Cons
- Remote batteries absent
- not primary heat
The EUHOMY makes sense when a fireplace surround is broad but does not have much depth to spare. Its 60.1-by-17.2-inch face is only 4.3 inches deep, and the manufacturer lists wall-mount or recessed installation rather than a simple set-it-in-the-firebox approach.
I would put its visual control near the top of the list for a linear project: 12 flame colors and 12 ember-bed colors make 144 stated combinations. It also includes both a log set and crystal stones, so the look can change without replacing the appliance.
The heat setup is best for a medium supplemental-heating zone
The dual 750-watt and 1500-watt settings are listed for coverage up to 400 square feet, with a temperature setting up to 82 F. That makes it a supplemental heater, not a replacement for a home’s central heating system.
The installation fit is best for a purpose-built shallow recess
Measure the entire 60.1-inch width, 17.2-inch height, and 4.3-inch depth before cutting or ordering a surround. The touch panel, remote, one-to-eight-hour timer, tempered glass, and ETL safety certification add useful everyday control once the opening is ready.
2. The best compact recessed choice is the LegendFlame Austin 33-Inch
Pros
- Plug-in or hardwire
- crackle sound
- log and crystal options
- thermostat
Cons
- Needs 120V 15A circuit
- not primary heat
The Austin is a compact electric fireplace insert for an existing fireplace project that needs a 33-inch front rather than a long linear panel. Its overall dimensions are 33 by 18.9 by 5.8 inches, and its listed insert dimensions are slightly smaller at 31 21/32 by 18 5/16 by 5 19/32 inches.
Its useful distinction is connection flexibility: the manufacturer lists both plug-in and hard-wire options. The unit also includes log and crystal fuel-bed choices, five brightness settings, a thermostat, a countdown timer, and a crackling effect that works with or without heat.
The electrical choice is best when a dedicated circuit is available
The manufacturer specifies a 120-volt, 15-amp circuit. Have a qualified electrician assess a hard-wired plan, and do not assume the existing fireplace opening already has the right outlet or circuit capacity.
The ambience is best for a smaller contemporary hearth
Five flame-brightness levels and the switchable crackle effect let the visual settings run independently from heat. The stated 400-square-foot coverage gives a realistic frame for supplemental comfort in a bedroom, office, or modest sitting room.
3. The best app-controlled choice is the Westinghouse 50-Inch Smart Fireplace
Pros
- App and voice control
- 144 color combinations
- 24 hour timer
- 2 year warranty
Cons
- 120V 15A dedicated circuit
- listed coverage is 51.1 sq ft
The Westinghouse is the control-focused option in this group. It fits a stated 49-by-15-by-6-inch opening, measures 50 by 15.75 by 5.5 inches overall, and works through the Westinghouse app, the remote, Alexa, and Google Home.
The controls go beyond an on-off command: there are five flame speeds, five brightness levels, 144 flame-and-ember color combinations, a 62 to 82 F thermostat range, and a 24-hour timer. It also includes interchangeable log, camphor wood, and crystal media.
The smart-home fit is best for voice-control households
Alexa and Google Home compatibility can be useful when the fireplace is part of an evening routine. I would still keep the supplied remote accessible, because direct controls are simpler for guests and useful if a network connection is unavailable.
The heating claim needs a cautious reading
The product listing gives 5110 BTU and 1500 watts but also lists heating coverage at 51.1 square feet. Treat the model as local supplemental heat and plan the selection around opening fit and control features rather than a large-room heating promise.
4. The best traditional presentation is the LegendFlame Damon 35-Inch
Pros
- Brick interior
- realistic resin log
- crackle sound
- freestanding or recessed
Cons
- Plug-in only
- not primary heat
The LegendFlame Damon speaks to owners who want the old fireplace opening to retain a conventional hearth look. A glass door, mesh screen, three-sided brick interior, and resin log give it more physical visual layers than a flat-front linear unit.
It measures 38.7 by 26.1 by 11.6 inches, so this is not the pick for a shallow firebox. It offers four brightness levels, five flame-speed settings, nine mood-light settings, crackling sound, and 750-watt or 1500-watt heat.
The visual style is best for a deep traditional fireplace
The door-and-screen design will appeal to people who dislike the bare glass-panel look common in recessed electric fireplaces. The interior brick and log treatment can help a former wood-burning opening feel more finished without ash or smoke.
The placement flexibility is best when wiring must stay simple
The manufacturer lists freestanding, insert, and recessed placements, but it also says the Damon cannot be hard wired. Plan for plug-in use and confirm that the 11.6-inch depth leaves the specified clearances inside the existing opening.
5. The best small smart log set is the ORALNER 26-Inch WiFi Insert
Pros
- Place and plug setup
- 3D flame effect
- crackling sound
- 5 brightness levels
Cons
- Only 85 reviews
- large coverage claim needs caution
The ORALNER is made for an existing firebox that needs a compact log-set solution instead of a built-in frame. At 26 by 14 by 8.8 inches, it is far easier to accommodate than a wide wall fireplace, and the listing describes it as plug and play.
WiFi, Alexa control, and smartphone app control are unusual at this size. Its stated feature list also includes a dynamic 3D flame effect, five color modes, five brightness levels, an authentic crackling module, thermostat, and one-to-eight-hour timer.
The convenience is best for a no-construction fireplace conversion
For a dormant masonry fireplace, placing a unit, routing the cord safely, and plugging it into a suitable outlet is a much simpler path than reframing a recess. The realistic pinewood log is specifically positioned for existing fireplaces and needs no ash cleanup.
The heat claim is best treated as supplemental guidance
The listing states 1500 watts, 5120 BTU, and up to 1000 square feet, a larger area than many similar products claim. Room insulation, layout, and thermostat set point all change real results, so I would not buy it as sole heat for that amount of space.
6. The best trim-kit option is the PuraFlame Western 33-Inch
Pros
- Trim kit
- resin log
- brick interior
- easy removal
Cons
- Plug-in only
- not main heat
The PuraFlame Western is designed around a traditional firebox conversion where a trim kit can cover the visual gap around the insert. The complete unit measures 44.1 by 27 by 8.8 inches, so use the full trimmed dimension when deciding whether it will work with a mantel and facing.
It pairs a life-like resin log with a three-sided interior brick wall and glass front trim. Three flame settings offer variable intensity and brightness, while the 750-watt and 1500-watt heater, adjustable thermostat, remote, and LED technology cover the daily basics.
The finish is best when the opening needs visual coverage
A trim kit can make a retrofit feel intentional where the existing opening is larger than the active fireplace face. That is different from making the appliance smaller; the firebox still needs enough interior space for the stated 8.8-inch depth and safe placement.
The track record is best for buyers who value many reviews
This model has the largest review count in this selection, with 4,578 reviews and a 4.7 rating in the supplied product data. The manufacturer calls it supplemental heat for up to 400 square feet and says it cannot be hard wired.
7. The easiest place-and-plug choice is the LegendFlame Nora 25-Inch
Pros
- Resin logs and ember bed
- remote with batteries
- CSA certified
- 20.8 lb
Cons
- No smart control
- not primary heat
The LegendFlame Nora is a freestanding electric fireplace log insert that measures 25 by 20 by 10 inches and weighs 20.8 pounds. That size works well for a small or larger existing opening when you prefer not to build a permanent surround around an appliance.
Its resin logs and ember bed aim for a classic firebox view, supported by LED flame effects and a remote that includes two AAA batteries. The product is CSA certified, includes a one-year limited warranty, and is listed for rooms up to 400 square feet.
The fit is best when the opening is deep but not wide
A ten-inch depth is manageable in many masonry fireplaces but should never be assumed. Measure at the narrowest point, account for the cord route, and leave whatever clearance the manual requires around the unit.
The control set is best for uncomplicated daily use
The Nora does not add WiFi or a broad set of color controls, which may be a benefit for buyers who want fewer settings. Its remote-operated heater and log look target an uncomplicated conversion, while the 5000-BTU listing remains supplemental rather than primary heat.
8. The best broad traditional trim choice is the LegendFlame Carl 30-Inch
Pros
- Extra trim kit
- brick interior
- 9 mood lights
- insert or recessed
Cons
- Plug-in only
- two packages may arrive apart
The LegendFlame Carl combines a 30-inch insert format with an extra trim kit, producing overall dimensions of 39.7 by 28.8 by 10.4 inches. That broader finished face can be a good answer when an existing opening is visually wide but you still want a compact traditional flame area.
It uses a life-like resin log, three-sided brick interior, clean glass trim, four brightness settings, and nine mood-light settings. The manufacturer lists freestanding, insert, and recessed installations along with an adjustable thermostat and remote.
The trim is best when a tidy retrofit edge matters
The extra trim can hide some of the exposed opening around the fireplace face, but it does not alter the chassis depth. Confirm that the firebox can take 10.4 inches deep and nearly 29 inches high before treating the trim as a solution.
The flame control is best for a traditional room with accent lighting
Four brightness choices make it simpler to reduce flame intensity after dark, while nine mood-light settings add color around the log presentation. The unit can run with or without the heater, which lets ambiance stay available in warmer weather.
9. The best ultra-thin safety-feature choice is the Tehanld 60-Inch
Pros
- Ultra-thin design
- child lock
- 60 to 99 F thermostat
- 12 hour timer
Cons
- No smart compatibility
- coverage not listed
The Tehanld has the shallowest stated chassis in this roundup at 3.5 inches deep, with a 60-by-17-inch face. It offers fully recessed, semi-recessed, and flat wall-mounted installation, which is useful when a current fireplace wall has very little cavity depth.
The model lists a digital thermostat from 60 to 99 F, three power settings of off, 750 watts, and 1500 watts, a 12-hour timer, and overheat protection. Families may also value the child lock and cool-touch LED screen.
The depth is best when a former fireplace cannot spare much space
A 3.5-inch cabinet depth can reduce the amount of framing needed for a sleek linear conversion. Verify ventilation and clearance instructions in the supplied manual rather than pushing the unit tight against masonry, framing, or combustible finishes.
The quiet-operation claim is best for a bedroom-adjacent room
Tehanld lists operation at 40 decibels, although room acoustics and fan settings affect what you hear in practice. Its 12 flame colors, 12 ember colors, six brightness levels, faux logs, and crystals provide many visual settings without smart-home functions.
10. The best compact furniture-recessed choice is the Innoflame 23-Inch
Pros
- Compact size
- 64 to 82 F thermostat
- cool-touch glass
- CSA and UL listed
Cons
- No smart control
- not primary heat
The Innoflame is a compact unit for a small fireplace surround, cabinet, or furniture recess. The overall housing is 24 by 20.2 by 5 inches, while the stated visible insert size is 23 inches wide by 19 3/4 inches high.
It pairs a log set and dancing flame effect with four brightness levels, a remote and control panel, a 64 to 82 F thermostat, one-to-eight-hour timer, and overheat protection. The front tempered glass is described as cool to the touch.
The size is best for a narrow opening with a shallow cavity
At 19 pounds, this is one of the easier units to handle during a furniture retrofit, but its installation must still support the appliance correctly. The listing says it recesses into furniture from back to front, so it is not a drop-in replacement for every masonry firebox.
The heat control is best for a small occupied area
The 1400-watt heater and 5000-BTU listing are paired with a stated 400-square-foot room figure. I would treat the adjustable thermostat and modest dimensions as a good match for close-range supplemental comfort, not whole-house heating.
11. The best masonry-smart choice is the Touchstone Fireplug 33-Inch
Pros
- Designed for masonry fireplaces
- smart app control
- crackle speaker
- 13 ember colors
Cons
- Only 16 reviews
- one year warranty
The Touchstone Fireplug is the most directly targeted option for an existing masonry fireplace. It measures 33 by 26 by 7.88 inches, requires a chamber width of 31 inches and a chamber depth of 8 inches according to the product data, and is described as a freestanding insert.
Its feature set is unusually complete: six flame colors, five flame speeds, 13 ember-bed colors with a pulsing option, 13-color down lighting, and an adjustable-volume crackle speaker. It is also compatible with Alexa, Google Home, and a smartphone app.
The masonry fit is best when the existing firebox meets the chamber measurements
This is the product I would measure for first if the project is a straightforward masonry conversion with a 31-inch-plus interior width. Verify the 7.88-inch appliance depth, the eight-inch chamber-depth requirement, the outlet location, and all manufacturer clearances before placing it.
The control range is best for people who want ambience on a schedule
Its thermostat runs from 68 to 88 F, and the timer is programmable from 30 minutes to eight hours. The 750-watt and 1500-watt heater settings and stated 400-square-foot coverage describe supplemental heating, while the sound and lighting controls carry the ambiance load.
12. The best simple adjustable log set is the PuraFlame 27-Inch
Pros
- Place and plug fit
- crackle sound
- 0.5 to 9 hour timer
- clear LED display
Cons
- No smart compatibility
- 400 sq ft limit
The PuraFlame 27-inch log set is the uncomplicated option for many existing fireplace openings. It measures 27 by 19.9 by 9.8 inches and is designed to be placed in the opening and plugged in, without a recessed wall installation.
The unit offers six flame colors, five brightness levels, crackling sound, an LED display, 750-watt and 1500-watt heat levels, and a thermostat adjustable from 60 to 82 F. A timer from 30 minutes to nine hours can also shut the unit down automatically.
The setup is best when you want a reversible fireplace update
A freestanding log set can be removed more easily than a built-in unit if the home changes or the fireplace needs service. It still needs a stable, level placement and a safe electrical route, rather than an extension cord hidden under a rug or pinched by a screen.
The controls are best for changing the mood without heating
The flames can operate without heat, making this choice useful when the room only needs visual warmth. The manufacturer states coverage up to 400 square feet and includes overheat protection, but it says the model is not a primary heat source.
The right buying decision begins with the fireplace opening
Start with the smallest interior width, height, and depth of the existing fireplace, not the face opening or mantel width. Measure several points because old masonry openings can taper toward the back, and record the location of the outlet before deciding between a log set and a recessed electric fireplace heater insert.
A plug-in log set such as the PuraFlame 27-inch, LegendFlame Nora, or ORALNER is generally the lower-construction route because it sits inside the opening. A wide linear model such as the EUHOMY or Tehanld is a recessed or wall-mounted product; it may suit a rebuilt surround better than an untouched masonry firebox.
The heating rule is that 1500 watts means supplemental comfort
Many entries here offer 750-watt and 1500-watt modes, and several are listed around 5000 BTU with coverage claims near 400 square feet. Those figures are useful for comparison, but insulation, ceiling height, draft, outdoor temperature, and fan placement all affect results.
Choose an electric fireplace insert for the seat, bed, desk, or living area you want to make more comfortable, not as a central furnace replacement. The product data repeatedly labels these units as supplemental rather than main heat, and that limitation should guide the purchase.
The realistic-flame rule is to look for physical depth and independent controls
Forum discussions repeatedly flag fake-looking flames as a buyer concern. Based on the verified feature lists, a resin log, brick interior, glass door or screen, adjustable brightness, variable flame speed, ember lighting, and optional crackle can create a more layered presentation than a single static panel.
The Damon, Western, and Carl add traditional visual details such as brick interiors and resin logs. For a color-forward linear style, the EUHOMY, Westinghouse, Tehanld, and Touchstone give more specified flame and ember combinations; there is no objective head-to-head flame test in the supplied data, so I would not call one universally most realistic.
The electrical rule is to follow the unit manual instead of guessing
Electric inserts are vent-free, but vent-free does not mean installation-free. Models that plug in still require an appropriate outlet, while the Austin offers hard-wiring and the Westinghouse specifies a 120-volt, 15-amp circuit with no other appliances on the same circuit.
Do not block required ventilation areas, alter the cord, or bury it behind materials that can pinch it. If the project needs a new outlet, a hard-wired connection, a wall recess, or any masonry modification, use a qualified electrician or installer and follow local requirements.
The alternative is better when an insert is not the right shape
If your fireplace opening is too shallow or the home does not have a usable hearth, a wall-mounted unit can be more practical; compare premium wall-mounted electric fireplaces before rebuilding the fireplace surround. Buyers seeking a mantel rather than an insert can also consider luxury freestanding electric fireplaces.
For a living room that needs furniture and heat in one footprint, electric fireplace TV stand entertainment consoles are another route. Each alternative changes the room layout, so it is worth choosing the installation type before falling in love with a flame effect.
FAQs
Can you put an electric fireplace insert in an existing fireplace?
Yes. An electric fireplace insert can go in an existing fireplace if the appliance fits the measured opening, required clearances are maintained, and the electrical instructions are followed. Electric models create LED flame effects and supplemental heat without a chimney or combustion vent.
Which inset electric fireplace is the best?
The best inset depends on the opening and installation. Choose the EUHOMY 60-Inch for a wide, shallow recessed project, the Touchstone Fireplug for a masonry fireplace with smart controls, or the PuraFlame 27-Inch for a simple place-and-plug log-set conversion.
Which electric fireplace insert has the most realistic flame?
There is no verified head-to-head realism test in the supplied data. For a traditional layered look, the LegendFlame Damon combines a resin log, brick interior, glass door, mesh screen, variable brightness, flame-speed settings, and crackling sound. For a linear look, the EUHOMY offers many flame and ember color combinations.
What is the best electric fireplace according to consumer reports?
This guide does not reproduce Consumer Reports testing or declare its winner. It compares the verified dimensions, controls, heating specifications, warranty details, ratings, and limitations of the 12 products listed here, so you can match a model to your fireplace opening and intended use.
The best electric fireplace inserts for existing fireplaces match the opening first
For a wide shallow rebuild, the EUHOMY has the most accommodating listed depth. For a smart masonry conversion, choose the Touchstone Fireplug after confirming its chamber measurements; for a no-construction log look, the PuraFlame 27-inch is the straightforward starting point.
Measure the firebox at its tightest points, confirm the electrical plan, and select the flame style you will enjoy living with in 2026. That fit-first approach makes an electric fireplace insert conversion far more likely to look intentional and work comfortably.
