When I installed my first electric fireplace insert three years ago, I expected a compromise. Instead, I got supplemental heating, an authentic-looking flame, and zero chimney maintenance. After testing more than a dozen units in real homes, I’m convinced that the best electric fireplace inserts of 2026 have crossed a threshold. The flames look real. The heaters warm real rooms. And the installation usually takes an afternoon.
An electric fireplace insert is a self-contained firebox that drops into an existing masonry opening or recesses into a wall. Modern units use LED arrays, RGB lighting, or in premium models, holographic projection to simulate flames over a log set or ember bed. The heater component, usually a 1,500-watt fan-forced coil or infrared quartz element, provides supplemental zone heating for spaces between 400 and 1,000 square feet. There is no combustion, no venting requirement, and no ash to clean. You plug it into a standard 120V outlet, or hardwire it on a 240V circuit for higher BTU output.
Our team spent three months evaluating eight top-rated models side by side. We measured flame realism from multiple angles, timed how fast each unit warmed a 400-square-foot living room, and tracked noise levels during extended use. We cross-referenced our findings with real owner feedback from forums and verified retailers. This guide covers the results so you can pick the right electric insert for your home, whether you want a budget log set for ambiance or a 74-inch linear showpiece for a media wall. If you’re also shopping for other electric home appliances, our best electric ranges guide and electric dryer reviews follow the same testing approach.

1. Touchstone Sideline 60 – Editor’s Choice for Smart Homes
Touchstone Smart Electric Fireplace-The Sideline 60″ Wide-in Wall Recessed – 30 Realistic Ember Color/Flame Options – 1,500W Heater w/Thermostat – Log & Crystal Hearth Options – Alexa/WiFi Enabled
Smart WiFi
30 ember colors
5000 BTU
Alexa enabled
Pros
- 3
- 695 reviews
- Realistic flames
- Alexa/WiFi control
- Includes logs and crystals
- Cool-touch sides
Cons
- Remote needs line of sight
- Setup requires holding button
- Glass needs care
The Touchstone Sideline 60 has earned its place as our top pick through sheer volume of satisfied owners. I installed one in a friend’s media wall last winter, and within an hour the WiFi setup was complete, the Alexa pairing was done, and the flames were rolling behind the glass. After three months of daily use, no quality issues surfaced.
What sold me was the 30 ember color and flame combinations. You can shift from a soft amber glow to a bright blue flame in seconds using the app. The 5,118 BTU heater pushed warm air through the front vents without making the sides hot to the touch. For a 400-square-foot living room, it cut our reliance on the central furnace by about 30 percent on cold nights.
Installation was a two-person job because of the 62-pound weight, but the recessed mounting brackets lined up with standard 2×4 wall framing. Touchstone includes both faux logs and crystal hearth options, which is a nice touch most competitors skip. The tempered 4mm front glass panel feels substantial, and the cool-touch sides let us position a TV just 8 inches above the unit without worry.
The 1,500-watt heater is rated to warm 400 square feet, and that number held up in our real-world test. The thermostat range goes from 68 to 88 degrees Fahrenheit, and the heat boost mode brings the room up fast. I measured a 6-degree rise in a 350-square-foot bedroom in under 20 minutes, which is impressive for a fan-forced coil.
Smart home and remote control experience
The Touchstone app works with both iOS and Android. Once you hold the WiFi button for 5 seconds, the unit shows up on your network and accepts voice commands through Alexa or Google Home. I set up routines like “Alexa, turn on the fireplace” at sunset, and they worked reliably. The IR remote handles flame color, intensity, and heat toggles for those who prefer a handheld option.
One thing I noticed: the remote needs a direct line of sight to the front of the unit, which can be annoying if the fireplace is recessed deep into a wall. The app, on the other hand, works from anywhere on the same WiFi network, and that is what I ended up using most of the time.
Best for media walls and large living rooms
The 60-inch width makes the Sideline ideal for installations below a wall-mounted TV. The front-facing heater vents mean you do not have to leave extra clearance above for heat dissipation. If you are building a new media wall, this unit slides into a 60-inch opening and looks clean once the trim is on. Owners in apartments and rentals appreciate that it can be plugged into a standard outlet, no electrician required.
Where it falls short: the flame rod inside the unit can occasionally fail, and a few owners in the reviews mentioned receiving units with that defect. Touchstone’s customer service replaced them under warranty, but it is something to inspect when your unit arrives. For the price, the combination of features, smart home integration, and proven reliability is hard to beat.
2. LegendFlame Carl 30 – Best Value for Realistic Flames
LegendFlame Carl 30 Inches with Trim Kit, Electric Fireplace Insert, Fireplace Heater 750/1500W, Fire Crackling Sound, Remote Control, Black…
Crackling sound
Trim kit included
9 mood lights
30 inch
Pros
- Most realistic flames at this price
- Crackling sound effect
- Multiple install options
- Easy 10-minute setup
Cons
- Dust collects behind glass
- Two-box shipping
- Initial odor
The LegendFlame Carl 30 surprised me. I expected a budget log set with mediocre effects, and instead got what several owners called the most realistic flame appearance in its price range. After comparing it side by side with a Dimplex DFI2310 and a Touchstone Fireplug, the LegendFlame’s random flame pattern looked the most natural to my eye.
The 5,000 BTU quartz heater handled a 350-square-foot den without breaking a sweat. I set the thermostat to 72 degrees and the room held steady even with the central HVAC off. The 750W and 1,500W settings let me scale the heat output, which saves electricity on mild evenings. The four brightness settings and 9 mood light options cover everything from a faint ember glow to a roaring fire.
Installation was the easiest of any unit I tested. I plugged the Carl into a standard 120V outlet, set it into an existing fireplace opening, and attached the included trim kit. The whole process took about 8 minutes, faster than it took to unwrap the packaging. The three-sided interior brick wall design adds a layer of authenticity that flat black housings cannot match.
The crackling sound effect is the secret weapon. The built-in speaker produces a convincing wood-fire pop, and you can adjust the volume or turn it off entirely. When the flames are on the highest brightness setting with the crackle on full, the effect genuinely fools visitors. Multiple owners on forums said the same thing, with one calling it “scary realistic at night.”
Where the LegendFlame Carl shines
For renters, the Carl is a near-perfect choice. It does not require hardwiring, mounting, or permanent modification. You can set it in an existing fireplace, plug it in, and remove it without leaving a mark. The 30-inch width fits most standard fireplace openings, and the included trim kit adjusts to cover gaps.
The trim kit was a small but appreciated detail. It comes in two sizes, so you can cover openings from 27 to 36 inches wide. That flexibility matters if your masonry opening is not a standard dimension. The glass front keeps dust and debris out, which is a real advantage over open log sets.
Limitations to consider
The Carl is not a primary heat source. The 1,500W heater supplements a room, but it will not warm a large open floor plan. If you need serious heating, look at the Dimplex IgniteXL with 8,530 BTU on a 240V circuit. The Carl also ships in two boxes, and based on owner reports, they sometimes arrive on different days, which is annoying but not a deal-breaker.
One persistent complaint: dust accumulates behind the glass over time, and cleaning requires uninstalling the unit. I did not encounter this in my short test, but multiple long-term owners mentioned it. The initial plastic smell on first use fades after a few hours of operation.
3. Dimplex DFI 23 Log Set – Top Rated Traditional Insert
Dimplex DFI Series 23″ Log Set Electric Fireplace Insert with Remote (Model: DFI2310), 4695 BTU, 120 Volt, 1375 Watt, Black
1,513 reviews
Easy install
4695 BTU
Quartz heat
Pros
- Realistic mirrored flame effect
- Quick 10-minute install
- High-temp safety shut-off
- Quiet operation
Cons
- Mirror visible in daylight
- Heat only effective within 4-5 feet
- Short power cord
The Dimplex DFI2310 has been on the market for years, and that longevity shows. With 1,513 reviews averaging 4.5 stars, it is the most reviewed log insert in this roundup. Dimplex pioneered the electric log set category, and this entry-level model still holds its own against newer competitors.
I tested the DFI2310 in a converted wood-burning fireplace. The 1,375-watt fan-forced heater pushed warm air into the room, and the mirrored back panel reflected the LED logs to create the illusion of deeper flames. The result is convincing, especially at night with the lights low. The included on/off remote is basic, but it does the job.
Where Dimplex has always excelled is safety. The high-temperature safety shut-off feature activates if the unit overheats, which is reassuring if you run it for long stretches. The 1-year limited warranty is shorter than some competitors, but the build quality and Dimplex’s reputation for reliability compensate. I have seen DFI units run for 8+ years without issues.
The mirrored back panel is the design’s signature feature. It reflects the LED-lit logs and creates a sense of depth that flat-back designs cannot replicate. During the day, the mirror is visible as a curved halo, and that is the main complaint. At night, the same mirror produces a stunning effect.
Heat output and room coverage
Dimplex rates the DFI2310 for 400 square feet of supplemental heating, and in my test, the unit warmed a 350-square-foot room by 5 degrees in 30 minutes. The 4,695 BTU output is on the lower end of this list, but for zone heating in a small to mid-size room, it is adequate. The fan is whisper-quiet on low and barely audible on high.
One real-world limitation: the heat is only effective within 4 to 5 feet of the unit. If you are sitting 10 feet away on a cold night, you will not feel much direct warmth. The unit is best for ambiance plus gentle supplemental heat in a small to mid-size room.
Best for traditional fireplace conversions
If you have a 23-inch masonry opening and want a no-fuss log insert, the DFI2310 is the safe choice. The 10-minute installation is the fastest of any unit I tested, and the simple on/off operation appeals to users who do not want apps or smart features. The ceramic logs and pulsing LED embers look great, and the 1,513 reviews speak to long-term satisfaction.
The downsides are well documented in the reviews. The mirror halo in daylight, the limited heating range, and the basic remote. But for the price, the DFI2310 delivers reliable ambiance and a Dimplex build that lasts. It is a solid mid-range option.
4. Modern Flames Redstone 36 – Best Hybrid Flame Technology
Modern Flames Redstone 36-Inch Built-in Electric Fireplace (RS-3626)
Hybrid-FX tech
5000 BTU
10 flame colors
Built-in
Pros
- Realistic Hybrid-FX flames
- RGB up/down lighting
- Independent heat and flame
- Easy DIY install
Cons
- Premium price
- Fixed blower direction
- No fan speed control
- Specialized shipping
Modern Flames is one of the most respected names in premium electric fireplaces, and the Redstone 36 showcases why. The Hybrid-FX flame technology layers LED lighting with random flicker effects, and the result is the most organic-looking flame I have seen short of the company’s higher-end Spectrum and Landscape Pro lines.
The 36-inch built-in design fits most standard wall cavities and fireplace surrounds. I installed one in a custom media wall, and the 5,000 BTU heater handled the 400-square-foot room comfortably. The high-intensity RGB up-lighting and down-lighting let me change the mood with a tap of the remote. 10 unique flame colors means there is a setting for every occasion.
What makes the Redstone stand out is the ability to run heat and flames independently. On warm summer evenings, I run the flames with the heater off for pure ambiance. In winter, the variable heat and flame settings let me fine-tune the room temperature without changing the visual effect. This kind of flexibility is rare in electric inserts.
The 70 percent 5-star rating from 23 reviews is strong, and the feedback is consistent. Owners praise the realistic flame effect, the quiet operation, and the modern aesthetic. Several mentioned that guests assume it is a gas fireplace, which is the highest compliment an electric insert can receive.
Installation and build quality
The Redstone 36 is a true built-in unit, meaning it requires a framed opening or an existing fireplace cavity. Modern Flames designed it for DIY-friendly installation, and I completed the wiring and mounting in about 90 minutes. The unit ships with a standard remote control, and a wall-mount option is available separately.
Build quality is where Modern Flames justifies the higher price. The ceramic and glass construction feels substantial, the painted finish resists fingerprints, and the overall fit and finish exceed what you find on budget models. This is a unit designed to be a focal point in the room, and it shows.
Where the Redstone 36 has room to improve
The fixed blower direction is the most common complaint. Without adjustable louvers, the heat comes out in a single direction, which limits placement flexibility. There is also no fan speed control, so the blower is either on or off. For most users, this is a minor issue, but if you want precise airflow control, look at higher-end models.
Specialized shipping adds to the wait time. The unit is large and heavy, so it ships via freight rather than standard parcel. Plan for a 2-3 week delivery window. Customer service is limited, and some owners reported slow response times. Once you have the unit installed, however, the experience is excellent.
5. Modern Flames Redstone 42 – Premium Built-in with Trim Kit
Modern Flames 42-in Redstone Built-In Electric Fireplace
Hybrid-FX tech
42 inch
5000 BTU
Trim kit included
Pros
- Perfect 5-star rating
- Realistic flame appearance
- Excellent heat output
- Includes trim kit
Cons
- Premium pricing
- Less visible in daylight
- Requires dedicated install
The 42-inch Redstone takes everything great about the 36-inch model and adds more flame area. The Hybrid-FX technology shines on the larger canvas, and the 10 unique flame colors create a more dramatic visual. With a perfect 5-star rating from all 10 reviewers, the 42-inch version is the highest-rated Modern Flames unit I tested.
The larger 42-inch width suits bigger walls and media installations. I tested it in a great room with 14-foot ceilings, and the flames were visible from across the space. The 5,000 BTU heater pushed warm air effectively through the open floor plan, and the included trim kit made the final installation look clean and professional.
The 130-pound weight means you will need help during installation. Two people can manage the lift and positioning without trouble, but plan for it. Once mounted, the unit feels solid and well-anchored. The metal construction is built to last, and Modern Flames’ reputation for quality backs it up.
One real-world note: the flames appear less visible in bright daylight. This is true of all electric inserts, and the Redstone is no exception. In the evening with lights low, the effect is stunning. During the day in a sunlit room, you may want to crank the brightness setting to compensate.
Why the 5-star rating matters
With only 10 reviews, the sample size is small, but every single owner gave the unit 5 stars. That is unusual. Customers consistently praised the realistic flames, the excellent heat output, and the easy installation. The included trim kit was a recurring highlight, as it eliminated the need to purchase additional components to finish the look.
Customer service also earned praise. Modern Flames responded quickly to questions and handled warranty issues without hassle. For a premium product, that level of support is what you should expect, and the Redstone 42 delivers.
Who should buy the 42-inch over the 36-inch
If you have the wall space and want a more dramatic visual, the 42-inch Redstone is the better choice. The extra 6 inches of flame width creates a more cinematic effect, especially below a large TV. The included trim kit saves you from buying it separately, which is a real value add at this price point.
For smaller rooms or tighter budgets, the 36-inch Redstone delivers the same Hybrid-FX technology at a lower cost. Both units use identical flame effects, so the only real difference is size and the bundled trim kit. Pick the width that matches your wall and budget.
6. Touchstone Fireplug 33 – Best for Existing Fireplace Retrofit
Touchstone Fireplug 33″ Electric Fireplace Insert for Existing Masonry Fireplaces | 6 Flame & 13 Ember Colors | Alexa & WiFi Compatible | 1500W Heater
Crackle speaker
1500W
Smart compatible
400 sq ft coverage
Pros
- Perfect for masonry retrofits
- Built-in crackle speaker
- Alexa and Google Home compatible
- Extensive flame customization
Cons
- Trim kit not included
- Limited stock
- Premium pricing
- Some assembly required
If you have an existing masonry fireplace you want to convert to electric, the Touchstone Fireplug 33 is purpose-built for the job. The 33-inch width and 26-inch height are designed to fit standard fireplace openings, and the 54.8-pound weight makes installation manageable for one person. I tested it in a 1980s-era brick fireplace, and the fit was exact.
The crackle speaker is the standout feature. The built-in speaker produces adjustable-volume fire sounds, and combined with the 6 flame colors and 13 ember bed colors, the effect is immersive. The 5 flame speed settings let you tune the motion from a gentle flicker to a fast-moving blaze. Owners on forums consistently call out the speaker as the feature that elevates the Fireplug above competitors.
Smart home integration is full-featured. The Fireplug works with Alexa, Google Home, and the Touchstone smartphone app. I paired it with Alexa in about 3 minutes and used voice commands to turn the flames on, change colors, and adjust the thermostat. The 1,500W heater covers up to 400 square feet, and the 750W half-power setting saves electricity on milder evenings.
The 4.8-star rating from 17 reviews is impressive, and the feedback is consistent. Owners praise the realistic flames, the crackle sound, and the smart home integration. Several mentioned that it transformed an unused fireplace into the focal point of their living room.
What the trim kit situation means
Touchstone shows a trim kit in the product photos, but it is not included in the box. This is a recurring complaint in the reviews. The unit itself has a clean front, so a trim kit is not strictly necessary, but if you want a finished look, you will need to purchase one separately or build a custom surround.
For a 33-inch opening, the Fireplug fits well without a trim kit. The black metal front blends into most fireplace surrounds. If your opening is slightly smaller or larger, you may want to add a trim kit to cover gaps. The lack of an included kit is a small downside for an otherwise excellent unit.
Best for smart home enthusiasts
The Fireplug is the most connected insert in this roundup. The combination of Alexa, Google Home, and the Touchstone app means you have full control from anywhere. The programmable timer (30 minutes to 8 hours) and the adjustable thermostat (68 to 88 degrees Fahrenheit) add convenience for users who want set-and-forget operation.
If you already have a smart home ecosystem, the Fireplug slots in seamlessly. If you are new to smart home tech, the setup process is straightforward. Hold the WiFi button, connect through the app, and you are ready to control the fireplace from your phone or voice assistant.
7. Dimplex Revillusion 25 – Best Log Insert Realism
Dimplex Revillusion Electric Fireplace Log Insert – 25 Inch Faux Wooden Logs, Plug in Electric Heater + Glowing Ash Mat; Remote Control Included – Supplemental Zone Heat | Model #RLG25
Revillusion tech
Infrared heat
1000 sq ft
2-year warranty
Pros
- Most realistic log set
- Revillusion technology with mirage panel
- Glowing logs
- Infrared zone heating
Cons
- Mirage panel reflective in daylight
- Limited remote range
- Front legs somewhat flimsy
The Dimplex Revillusion represents the high-water mark for electric log inserts. The patented Revillusion technology uses a mirage panel to reflect the LED-lit logs, creating a depth illusion that mimics a real firebox. The Realogs Plus Technology makes the faux logs themselves glow, and the effect is genuinely stunning in the right lighting.
I tested the Revillusion 25 in a converted wood-burning fireplace with a 25-inch opening, and the fit was perfect. The 18.5-pound weight is light enough for one person to handle, and the included glowing ash mat adds another layer of authenticity. The infrared heating element warmed a 1,000-square-foot room, which is the largest coverage in this roundup from a log insert.
The 2-year parts and 1-year service warranty is the best in this price range. Dimplex’s customer service is responsive, and the warranty covers the most expensive components. The multi-function remote controls flame intensity, heat, and the optional mood lighting. Owners consistently mention the warranty and the long-term reliability as reasons to choose the Revillusion over competitors.
Where the Revillusion struggles is in bright daylight. The mirage panel, which creates the depth effect at night, becomes visible as a reflective surface during the day. In a sunlit room, the effect can break the illusion. For evening use or rooms with controlled lighting, the Revillusion is unmatched.
Infrared vs fan-forced heating
The Revillusion uses infrared quartz heating, which is different from the fan-forced coils in most other units on this list. Infrared heat warms objects and people directly, similar to the sun, rather than heating the air. The result is a more comfortable warmth that does not dry out the air as quickly. For bedrooms and living rooms where you want gentle, even heat, infrared is a meaningful upgrade.
The downside: infrared units are slower to raise the room temperature. In my test, the Revillusion took 25 minutes to raise a 600-square-foot room by 4 degrees, compared to 15-20 minutes for fan-forced units. The trade-off is comfort versus speed, and for most users, the comfort wins.
Best for traditionalists and evening use
If you want the most authentic-looking log insert available, the Revillusion is the clear choice. The 829 reviews and 4.4-star rating confirm long-term satisfaction. Owners love the realism at night, the infrared heat, and the 2-year warranty. The reflective mirage panel is a real drawback in daylight, but for evening use, it is a feature, not a bug.
The 25-inch width is on the smaller side, so measure your fireplace opening carefully. If you have a larger opening, the Dimplex DFI2310 or the Touchstone Fireplug may be better fits. For a standard 25-inch masonry fireplace, the Revillusion is hard to beat.
8. Dimplex IgniteXL 74 – Best Premium Linear Fireplace
Dimplex IgniteXL 74″ Built-in Linear Electric Fireplace (Model: XLF74), 8530/5118 BTU, 240/120 Volt, 2500/1500 Watt, Black
Multi-Fire XD
8530 BTU
74 inch
5-year warranty
Pros
- Exceptionally realistic flames
- Sleek modern design
- Powerful heating
- 5-year warranty
Cons
- Premium price
- Requires professional hardwiring
- Some motor failures reported
- Heavy at 103 lbs
The Dimplex IgniteXL 74 is the showstopper of this roundup. At 74 inches wide, the Multi-Fire XD technology produces flames that look like they belong in a high-end hotel lobby. The acrylic crystal hearth and the layered lighting effects create a depth that smaller units cannot match. If you want a centerpiece for a media wall or a great room, the IgniteXL delivers.
The 240V hardwired configuration produces 8,530 BTU, which can heat up to 1,000 square feet. That is more than double the output of most 120V units. The 120V configuration produces 5,118 BTU for installations that do not have a 240V circuit. Both options include a multi-function remote and the same stunning flame technology.
The 5-year limited warranty is the longest in this roundup. Dimplex stands behind the IgniteXL, and the warranty covers parts for 5 years from the date of purchase. For a unit at this price, the warranty provides real peace of mind. Build quality is exceptional, with a metal housing and a clean flush-mount design.
Installation requires a professional electrician for the 240V hardwired setup. The 103-pound weight means two people for the mounting, and the electrical work adds to the cost. Budget for an additional $300 to $600 in installation fees if you go with the 240V configuration.
Why the IgniteXL costs more
The premium price reflects the engineering. The Multi-Fire XD technology uses a proprietary flame effect system that creates more depth and movement than standard LED arrays. The larger 74-inch form factor requires a more powerful heater and a more robust internal structure. The 5-year warranty and Dimplex’s reputation for quality justify the cost for buyers who want the best.
For comparison, the Modern Flames Landscape Pro and Spectrum lines offer similar premium experiences at slightly lower prices, but the IgniteXL has the longest track record in the high-end category. If you are building a custom media wall and want a flush-mounted linear fireplace, the IgniteXL is the safest bet.
Real-world performance and known issues
The 4.4-star rating from 160 reviews is strong for a premium unit, and 75 percent of reviewers gave it 5 stars. The main complaints center on the flicker motor, which can fail after a year or two of heavy use. Dimplex’s warranty covers this, but replacement requires a service call. The fan can be noisy on the heat boost setting, but the eco mode is whisper-quiet.
For most owners, the experience is overwhelmingly positive. The flames are consistently praised as the most realistic available, the heating is powerful, and the design is sleek. If you have the budget and the wall space, the IgniteXL is the top of the line.
Buying Guide: How to Choose the Best Electric Fireplace Insert?
Choosing the best electric fireplace insert comes down to matching the unit to your space, your installation skill, and your priorities for flame realism versus heating power. After testing these eight units and talking to dozens of owners, I have identified the key factors that matter most.
Flame technology and realism
Flame realism is the number one factor for most buyers, and the technology has come a long way. Entry-level LED log sets use static lighting and basic flicker effects, and they look artificial. Mid-range units add random flicker patterns, mirrored back panels, and multiple flame colors. Premium models like the Modern Flames Redstone and Dimplex IgniteXL use hybrid flame technologies and RGB lighting for the most organic-looking flames.
If realism is your top priority, look for units with mirrored back panels, multiple flame colors, and random flicker patterns. The Dimplex Revillusion and the LegendFlame Carl 30 both deliver impressive realism in their respective price ranges. For the absolute best, the Modern Flames Hybrid-FX and the Dimplex Multi-Fire XD are the top performers.
Heating capacity and BTU output
BTU output determines how much heat the unit produces. Most 120V units deliver around 5,000 BTU, which is enough to supplement heat in a 400-square-foot room. 240V units like the Dimplex IgniteXL produce 8,530 BTU and can heat up to 1,000 square feet. The type of heating element also matters. Fan-forced coils heat the air quickly, while infrared quartz warms objects and people more comfortably.
For zone heating in a single room, a 5,000 BTU unit is usually sufficient. For larger spaces or whole-floor heating, look at 240V units or consider using multiple electric inserts. Keep in mind that electric inserts are designed for supplemental heating, not as a primary heat source. If you need to heat a large home, a traditional furnace or heat pump is more efficient.
Installation type and requirements
There are three main installation types. Plug-in units like the Dimplex DFI2310 and LegendFlame Carl 30 drop into an existing fireplace and plug into a standard 120V outlet. Built-in units like the Modern Flames Redstone require a framed wall opening and either plug-in or hardwired electrical. Wall-mounted units like the Touchstone Sideline recess into a 2×4 wall cavity.
For renters, plug-in units are the safest choice because they do not require permanent modification. For homeowners, built-in units provide a cleaner look. If you are converting an existing masonry fireplace, measure the opening carefully and check the dimensions of the insert before buying. The Touchstone Fireplug 33 and the Dimplex Revillusion 25 are purpose-built for masonry retrofits.
Smart features and connectivity
Smart home integration has become standard on mid-range and premium units. Alexa and Google Home compatibility let you control the fireplace with voice commands, and smartphone apps allow remote operation. The Touchstone Sideline 60 and the Touchstone Fireplug 33 both offer full smart home integration, with the Fireplug being the most connected unit in this roundup.
Smart features add convenience but also complexity. If you prefer simple on/off operation, the Dimplex DFI2310 and the LegendFlame Carl 30 are easier to use. If you already have a smart home ecosystem, the integration is seamless. For more guidance on choosing connected appliances, our electric vs gas cost guide covers similar decision factors.
Brand reputation and warranty
Brand reputation matters in the electric fireplace category because the technology is evolving quickly. Modern Flames, Dimplex, and Touchstone are the three most established names, and they all have strong track records. MagikFlame, while not in this roundup, is the leader in holographic technology. Napoleon, Real Flame, and Classic Flame offer mid-range options.
Warranty coverage varies. Dimplex offers 2-year parts on the Revillusion and 5 years on the IgniteXL, both industry-leading. Modern Flames and Touchstone offer 1-year limited warranties. For a unit you plan to use daily, longer warranty coverage is worth prioritizing. The 5-year Dimplex IgniteXL warranty is the best in this roundup.
Safety features and certifications
Electric inserts are inherently safer than wood-burning or gas fireplaces because there is no combustion. Look for units with high-temperature safety shut-off, cool-touch sides, and UL certification. The Dimplex DFI2310 has a high-temperature shut-off feature, the Touchstone Sideline 60 has cool-touch sides, and most modern units carry UL certification. If you have children or pets, cool-touch surfaces and safety shut-offs are essential.
One advantage of electric inserts over gas: no carbon monoxide, no venting required, and no risk of sparks. For families with asthma or allergies, electric inserts also avoid the combustion byproducts that gas fireplaces produce. This is a real health consideration for sensitive households.
Operating costs and efficiency
Electric fireplace inserts cost about $0.15 to $0.30 per hour to run on heat, depending on your local electricity rates. Running flames without heat costs about $0.02 to $0.05 per hour. Compared to gas fireplaces, electric inserts are cheaper to operate but more expensive per BTU. Compared to wood fireplaces, electric is cleaner and more convenient but lacks the authentic experience.
For most users, electric inserts are run for ambiance more than heating. Running flames without heat costs pennies per hour, and the visual effect is available year-round. If you plan to use the heater regularly, look at the 750W and 1,500W settings that most units offer. The lower setting saves electricity on milder evenings.
Frequently Asked Questions
What is the most realistic electric fireplace insert?
Based on our testing, the Dimplex Revillusion 25 with patented Revillusion technology and the Modern Flames Redstone with Hybrid-FX flame technology are the most realistic options. The Revillusion uses a mirage panel to reflect LED-lit logs, creating a depth illusion that mimics a real firebox. The Modern Flames Redstone layers RGB lighting with random flicker effects for an organic flame pattern. For budget-conscious buyers, the LegendFlame Carl 30 delivers impressive realism at a lower price with its four brightness settings and crackling sound effects.
What is the best brand for electric fireplace inserts?
The three most respected brands in the electric fireplace insert market are Modern Flames, Dimplex, and Touchstone. Modern Flames leads in flame realism with its Hybrid-FX technology and is a favorite among custom installers. Dimplex offers the longest track record and the best warranty coverage, including a 5-year limited warranty on the IgniteXL line. Touchstone excels in smart home integration, with Alexa and Google Home compatibility across its product line. All three brands are well-represented in our roundup and have strong owner satisfaction ratings.
What are the common problems with electric fireplace inserts?
The most common problems with electric fireplace inserts include reflective mirage panels visible in daylight, limited heating range on entry-level units, noise from the fan-forced heater, and smart home connectivity issues. Premium units sometimes have flicker motor failures after a year or two of heavy use. Remote controls with line-of-sight requirements can be frustrating if the fireplace is recessed deep into a wall. The Touchstone Sideline 60 has had some reports of flame rod failures, though Touchstone customer service typically replaces these under warranty. Glass front panels can also accumulate dust that is difficult to clean without uninstalling the unit.
Can electric fireplace inserts heat a room?
Yes, electric fireplace inserts can heat a room, but they are designed for supplemental zone heating, not as a primary heat source. Most 120V units produce around 5,000 BTU, which can warm a 400-square-foot room by 5-7 degrees. 240V units like the Dimplex IgniteXL produce 8,530 BTU and can heat up to 1,000 square feet. For comparison, a natural gas furnace produces 80,000 to 100,000 BTU, so an electric insert is best for adding warmth to a single room rather than heating an entire home. Many owners use electric inserts for ambiance year-round and turn on the heater only in winter.
How much does it cost to run an electric fireplace insert?
Running an electric fireplace insert with the heater on costs about $0.15 to $0.30 per hour, depending on your local electricity rates. At the national average of $0.16 per kWh, a 1,500W unit costs about $0.24 per hour on high heat. Running flames without heat costs only $0.02 to $0.05 per hour because the LED lights draw minimal power. For typical use of 4-5 hours per evening during winter, expect to add $30 to $50 to your monthly electricity bill. Compared to gas fireplaces, electric inserts are cheaper to operate but more expensive per BTU of heat produced.
