A fake fireplace insert solves the oldest problem of a real hearth: the smoke, the ash, the constant cleaning, and the worry about sparks. You want the look and the warmth without ever stacking a single log or calling a chimney sweep. The search is about finding an insert that actually fits your opening, throws enough heat to take the chill off, and has flames convincing enough that guests do a double-take.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You are about to see eleven of the strongest options available right now for a fake fireplace insert, ranked by how they perform on heat coverage, flame realism, and ease of installation for the average homeowner.
Our Picks at a Glance
How To Choose The Best Fake Fireplace Insert
The right insert depends on three things: the exact size of your fireplace opening, the square footage of the room you want to warm, and how much time you want to spend on installation. A unit that is too deep will stick out; a unit with too low a heat output will leave a large room cold.
Measure your opening before anything else
Width, height, and especially depth are the dealbreakers. An insert that is 8.8 inches deep will not fit into a shallow 5-inch built-in cavity. Always check the chamber depth in the specs and compare it against your available space.
Match the heat to the room size
Most inserts list a heating coverage in square feet (often 400 sq ft) and a wattage (750W to 1500W). A 1500W unit can supplement a large living room but will not replace a central furnace. For a bedroom or small den, 750W is often plenty.
Decide between freestanding and recessed
A freestanding insert sits on the floor of your existing fireplace and only needs a nearby outlet. A recessed unit slides into a wall cavity or a built-in opening and gives a flush look. The same model sometimes supports both, but not always.

In‑Depth Reviews
1. RICHFLAME Gavin 33 Inches Electric Fireplace Insert with Log Speaker
Our pick — over 4.5★ from 500+ verified ratings; the strongest balance of quality and price.
The crowd favorite that slides into a wood-burning opening and actually looks like it belongs there.
This insert fools your guests better than any other here. Three flame settings and a built-in log speaker (a small speaker that plays crackling fire sounds) create a realistic sight-and-sound experience. Buyers report it “makes a cold and drafty room cozy.” The old brick interior has a fade effect near the flame area, and owners consistently call it realistic.
At 33 inches wide and 8.8 inches deep, it is a substantial unit made for standard wood-burning openings. It puts out 5118 BTUs from two heat settings (750W and 1500W) and comfortably warms up to 400 square feet. The crowd over at Amazon gives this unit a 4.8-star rating across 500+ ratings, with the appearance and heat output being the most-praised aspects by a wide margin. Owners also appreciate how easy it is to install—one called it a “perfect fit replacement.”
The trade-off is that the crackling sound from the speaker is not convincing for everyone. Many note you can simply turn the sound off and enjoy the visual alone. For most setups, this is the one to beat.
Why owners recommend it
- Appearance is praised most; the simulation brick interior and fade effect make the flames look expensive
- Heats a 400 sq ft room effectively with low and high settings for energy saving
- CSA certified with overheat protection for safe operation
The honest caveat
- Built-in crackling speaker sound is weak; most owners turn it off
- At 46.7 pounds, it is heavy to maneuver during installation
Your best bet if: you want the highest-rated overall insert with realistic brick interior and strong supplemental heat for a medium-sized room.
Think twice if: you need a shallow-depth insert—the 8.8 inch depth demands a deep fireplace or a built-in cavity.
2. Vabches 18 Inch Electric Fireplace Insert, Recessed Fireplace Heater
A shallow, compact heater that slips into tight TV stands and small built-ins without breaking the budget.
This Vabches unit is the entry-level option that still delivers a solid experience. With a chamber depth of only 5.2 inches, it is significantly shallower than the RICHFLAME Gavin (which is 8.8 inches deep), making it a far better fit for tight television consoles and entertainment centers. The advanced 3D flame technology uses ultra-high-intensity LEDs to create a warm glow that owners love.
It offers three adjustable flame brightness settings and a 1500W heater that covers up to 400 square feet. The thermostat lets you dial in a precise temperature between 62°F and 82°F. Owners appreciate the touch screen control panel in addition to the wireless remote. The product sits at a 4.4-star average from 390+ ratings, with appearance and heat performance tied as the top praised aspects.
While the heat output is strong for the price, some buyers in very cold climates report that the 1500W heater struggled to keep up in rooms over 400 square feet. Durability is a mixed bag—some units lasted for years while a few early adopters noted a failure over time.
Who it fits: This is the right pick for anyone with a shallow fireplace opening or an entertainment center that needs a compact, flush insert. The remote and touch screen add a modern touch that belies its budget-friendly price.
3. Tangkula 23 Inch Electric Fireplace Insert
A mid-size unit with 9 flame colors and an auto-cycle mode that lets you match any mood.
The Tangkula insert is all about customization. You get nine distinct flame colors with an auto cycle function, plus five brightness levels to dial the look from subtle to bold. The log bed is realistic and the overall build quality is praised by owners for feeling sturdy. It works equally well as a freestanding insert or a recessed mount.
At 1400W, it delivers 5000 BTUs of heat and covers 400 square feet. The built-in thermostat (62°F to 82°F) and a timer ranging from 30 minutes to 8 hours give you precise control over energy use. The 4.4-star average from 670+ ratings is backed by a strong following of owners who say the flames “look amazing” and fit perfectly in their TV stands.
The most common frustration is an occasional E0 error code that requires unplugging the unit to reset. It is not a widespread defect, but it is the one thing owners flag. The temperature adjustment is only possible via the remote, which is a minor inconvenience if you prefer the panel.
Best for: buyers who want a highly customizable flame display for pure ambiance, even when the heat is off. At 13 pounds, it is also one of the lighter options to handle.
4. COSTWAY Electric Fireplace Inserts 28.5-inch Wide
A 28.5-inch workhorse that warms a master bedroom reliably and looks great doing it.
The COSTWAY insert is a versatile unit that supports both recessed mounting and freestanding placement. It offers three flame colors and five brightness settings, so you can pick a cool blue winter look or a traditional orange glow. The ETL certification and overheat protection make it a safe choice for indoor use.
With two heat settings (750W and 1500W), it heats up to 400 square feet. The thermostat range of 62°F to 82°F is wider than some competitors, and the countdown timer goes up to 8 hours. One of its most popular features is the ability to run the flame effect without the heat, making it a year-round ambiance tool. The unit holds a 4.5-star average from 720+ ratings, with the top aspects being appearance and heat output.
A few owners note that the flame effect, while vibrant, looks more like rolling light than a dancing fire compared to pricier inserts. That is the trade-off at this price point. For most, the warmth and ease of use outweigh the visual nuance.
Why it sells
- Wide 28.5-inch face fills a standard fireplace opening with a clean, minimalist look
- Dual heat settings plus a summer-only flame mode give year-round flexibility
- Remote control handles every function including the timer and thermostat
The honest caveat
- Flame realism does not match the premium units; some describe it as a “rolling screen” effect
- At 27.5 pounds, installation requires a second set of hands
5. Homajor 30 Inch Electric Fireplace Insert
A 30-inch insert with two ember-bed styles and a dizzying 12-color flame palette for the truly design-obsessed.
This is the only insert in this lineup that gives you a choice between a traditional log set and shimmering crystal stones for the ember bed. On top of that, you get 12 different flame color settings (not just the usual 3) with 5 intensity levels. The design is incredibly modern and the high-intensity LEDs produce a bright, realistic flame.
The Homajor supports both recessed and wall-mounted installation. At just 4 inches deep, it is the slimmest option here—perfect for shallow walls or entertainment centers. It heats up to 400 square feet using 5120 BTUs, with a thermostat range of 62°F to 82°F. The 4.7-star average from 350+ ratings is among the highest in the list, and owners consistently praise the installation process and overall quality.
The only limitation is that some owners wish the thermostat had a wider temperature range. The “Berry” color name (which is the glossy black finish) might confuse some buyers at first glance. Otherwise, this is a premium-feel insert that punches well above its tier.
Perfect for: anyone redecorating who wants a statement piece that changes color to match the season or mood. The crystal stones are a unique touch that other units do not offer.
6. Duraflame Electric Log Set
A freestanding log set that mimics a real wood fire with infrared heat and adjustable flame speed.
The Duraflame is a different beast from the boxy inserts above. It is a log set designed to sit on the floor of an existing fireplace, with rustic pine logs that look like a real stack of firewood. The infrared quartz heating element is unique to this tier—it warms objects and people directly rather than just blowing hot air.
You can adjust the flame brightness, flame speed, and heat output independently. The remote control works from across the room. The unit produces 5200 BTUs of heat, and owners mention it kept a 600 square foot space warm when paired with an auxiliary heater. The 4.4-star average from 140+ ratings reflects a satisfied customer base, with appearance and heat output tied as top aspects.
The biggest catch is noise. Some owners find the heater blower loud, while others call it quiet—opinions are split. The requirement of an outlet within 6 feet can also be a constraint depending on your fireplace layout.
What makes it stand out
- Infrared heating warms objects directly, so you feel the heat faster than fan-forced units
- Adjustable flame speed and brightness give you control over the log’s burning intensity
- At 19.4 pounds, it is one of the easiest units to move and position
What to watch for
- The blower noise gets mixed reactions; some find it loud enough to be distracting
- At 11 inches deep, it needs a deeper fireplace opening than many competitors
7. Country Living 23 Inch Electric Log Set
A log set designed to warm a large space—up to 1000 square feet—with adjustable flames and crackling audio.
The Country Living log set, designed by the famous Country Living Magazine, targets buyers with large family rooms or open-concept spaces. While most 1500W inserts top out at 400 square feet, this unit claims a heating coverage of 1000 square feet. The bright LED flame projections produce realistic, adjustable fire effects, and the unit includes a crackling sound feature for the full experience.
It measures 23.8 inches wide and 9.1 inches deep, making it a compact fit for a pre-existing fireplace. The remote allows you to adjust flame brightness, temperature, and turn the heat off for year-round use. The 4.2-star average from 300+ ratings shows a satisfied audience, with appearance (69 mentions) and heat output (56 mentions) being the most discussed attributes.
The downsides are notable. Some customers note the control interface is confusing and the WiFi requires re-pairing every time the unit is turned off. The crackling sound received mixed feedback, with some calling it unrealistic. The 15-amp draw may require a dedicated breaker, which can be a costly installation if your home is not wired for it.
Ideal for: large rooms where you need a log-style insert with serious heating coverage. Just check your electrical capacity before purchasing.
8. Signature Design by Ashley 24 Inch Electric Infrared Fireplace Insert
A furniture-grade insert from a top brand that heats a room silently and looks like a permanent built-in.
Signature Design by Ashley is a household name in furniture, and their 24-inch infrared fireplace insert brings that same quality reputation. It delivers 5386 BTUs of infrared heat, which the brand says warms a mid-size room of 400 square feet without drying out the air. The quartz heating element and built-in blower operate very quietly, something owners consistently note as a major win.
The unit offers 7 pre-set temperature settings and 5 LED brightness levels, all controlled via a convenient remote. The black firebrick surround and realistic wood-burning flames create a classic fireplace aesthetic. At 8.75 inches deep, it fits many standard fireplace openings. The 4.6-star average from 750+ ratings puts it among the most trusted inserts on the market.
The trade-off is purely dimensional. Hot air rises, so the minimum heat setting is 71°F, which might be too warm for some users on a cool fall day. It is also heavy to lift solo, so plan for help during installation.
Great for: anyone upgrading an existing Ashley TV stand or replacing an old heater. The silent infrared operation and 7 preset temps make it a premium daily driver.
9. LegendFlame Carl 28 Inch Electric Fireplace Insert (EF262)
The most realistic looking large insert in the list, with a resin log and mood lights that create a high-end illusion.
The LegendFlame Carl is the insert owners call “blown away” and “best-looking value.” It has a life-like resin log set (logs made from molded resin that look like real wood) and a three-sided interior brick wall along the back and sides, giving the fire a deep, rich look. You get 4 flame brightness settings and 9 mood light settings to set the scene for romantic, celebratory, or peaceful moments.
At 28.66 inches wide and 10.39 inches deep, it is a large unit that requires a deep fireplace or a dedicated built-in. It produces 5000 BTUs of heat and covers 400 square feet. The 4.7-star average from 640+ ratings is backed by exceptional feedback on quality (93 positive mentions) and noise (86 positive mentions—meaning it runs quietly).
The main limitation is that the heater is explicitly described as supplemental, not a primary heat source. The glass front is large and solid, which requires careful handling during installation. Some owners note that the gap around the insert may require a trim kit for a finished look.
Why it wins
- Appearance is praised by 135 owners—the highest single aspect count across the entire lineup
- Mood lights and realistic resin log create a high-end illusion that looks expensive even when off
- Installation is simple; slides into a standard opening and plugs in
The honest caveat
- Deepest unit in the list at 10.39 inches; verify your opening depth before ordering
- Supplemental heat only—do not rely on it to warm a large, open home alone
10. Masarflame 33 Inch Electric Fireplace Insert
A 33-inch insert with a retro three-sided brick interior that transforms an old fireplace into a modern focal point.
At 33 inches wide and 24.7 inches tall, this is one of the larger inserts in the lineup. It is designed for freestanding or recessed installation and features a three-sided interior brick wall that gives it a classic, old-world feel. The life-like resin logs are paired with 3 color atmosphere lights and 5 variable flame intensities.
This unit delivers 5100 BTUs of heat (enough to warm a 400-square-foot room). It includes a built-in speaker for fire crackling sound, but that sound is the most-criticized feature—77 owners flagged it negatively. The remote control handles heat and flame functions easily. With a 4.5-star average from 920+ ratings, it is among the most-reviewed inserts here. Appearance (104 mentions) and heat output (83 mentions) earn the highest praise.
The power cord exits on the right side, which some owners discovered required drilling a hole in their fireplace to route it. The remote quality also drew some criticism. If you like the retro look, this is a solid choice, but the sound is best left turned off.
Pick this if: you have a large opening and want a retro brick-lined insert that looks like it was made for your fireplace. Just be ready to turn off the crackling sound and manage the side-cord routing.
11. Westinghouse 50 Inch Electric Fireplace Heater
A massive 50-inch statement piece that answers to your voice, with 144 color combinations to play with.
This is not an insert for a small fireplace—it is a room-defining centerpiece. The Westinghouse 50-inch model fits a 49-inch opening and offers a staggering 144 total color combinations for flames and embers. You can switch between interchangeable faux log and crystal ember bed sets for two distinct looks. It supports both wall-mount and flush recessed installation.
Smart home integration sets this insert apart. It works with Alexa and Google Home for voice control, plus it has a dedicated Westinghouse app and a traditional remote. The heater output is adjustable with a built-in thermostat (range: 62°F to 82°F), producing 5110 BTUs. The 4.8-star average from 340+ ratings is backed by owners who call it “stunning” and say it heats an entire open-concept house. Appearance and quality are the top-praised aspects.
The biggest catch is the price and complexity. At the premium tier, it is a significant investment. The manufacturer advises keeping at least 11.8 inches of clearance from the ceiling and other objects. A few owners note that the app only supports one phone at a time, which is a minor annoyance for a connected home.
What makes it special
- Smart home voice control with Alexa and Google Assistant separates it from every other insert
- 144 color combinations and changeable ember beds offer class-leading customization
- Owners praise the heat output, with some saying it heats their entire open-concept home
What to be aware of
- Large size (50 inches) requires serious wall space and clearance above and around it
- App limitation (single-phone support) is a small but real friction point for smart homes
Understanding the Specs
BTU Rating and Room Size
BTU stands for British Thermal Unit — it is a measure of how much heat an appliance can produce per hour. A higher BTU rating means the insert can warm a larger space more effectively. Most of the inserts here land between 5000 and 5400 BTUs, which is enough for a 400 square foot room. Do not expect a fake fireplace insert to replace a central furnace; think of it as a way to take the chill off a specific room.
Chamber Depth vs. Overall Depth
When looking at dimensions, the chamber depth is the critical number. It tells you how deep the main body of the insert is. The overall depth includes the front decorative trim. If your fireplace opening is only 5 inches deep, you need a unit with a chamber depth of 5.5 inches or less. A unit like the RICHFLAME Gavin at 8.8 inches deep will simply not fit without modifications.
Supplemental Heat vs. Primary Heat
Every insert in this lineup is designed as a supplemental heat source. That means it can make a small to medium room feel significantly warmer, but it is not powerful enough to heat an entire house in the winter. The heat output is measured in watts (usually 750W or 1500W). A 1500W setting heats faster and can warm a larger area, but it also uses more electricity. Many units cool down automatically when the target temperature is reached.
Flame Effect Technology
Modern fake fireplace inserts use LED lights and reflective technology to simulate dancing flames. The quality varies dramatically between budget and premium models. Higher-end units use 3D flame technology that creates the illusion of depth and movement. Some add a built-in speaker for a crackling wood sound effect. While the visual effect is convincing, the sound is still hit-or-miss — many owners prefer to turn it off and enjoy the quiet.

Final Thoughts: The Verdict
For most buyers, the fake fireplace insert winner is the RICHFLAME Gavin 33 Inches because it has the strongest combination of high rating, realistic brick-lined appearance, and effective 400-square-foot heat output. If you want a customizable display with smart home control, grab the Westinghouse 50 Inch. And for a compact, budget-friendly insert that fits into tight spaces, the Vabches 18 Inch is the one to reach for.
