How To Choose The Best 50 Inch Electric Fireplace
A 50-inch electric fireplace is a big purchase for your home, so knowing what to check before you buy saves you from a frustrating install or a unit that doesn’t warm your room the way you expected. Here are the key things to look at when comparing models.
Installation Method: Recessed vs. Wall-Mounted
The biggest decision is if you want the fireplace to sit flush inside your wall (recessed) or hang on the surface (wall-mounted). A recessed unit like the Touchstone Sideline Elite is designed for a built-in, custom look, but it requires cutting a hole in your drywall and building a frame. A wall-mounted model, such as the Tangkula, can be hung on an existing flat wall using a bracket. Some units, like the PuraFlame Bernice, offer both options plus freestanding placement, which gives you flexibility if you move or change your decor.
Heat Output and Room Size
Electric fireplaces produce supplementary heat — they won’t replace your central furnace in a large home. The heat output is measured in British Thermal Units (BTUs). Most 50-inch models put out around 5000 BTUs. The Tangkula claims to heat up to 500 square feet, while most others, such as the LegendFlame and the PuraFlame, are rated for 400 square feet. Your room size and insulation matter: a 400-sq-ft rating works well for a living room or large bedroom, but a drafty open-concept space may need more.
Flame Effects and Customization
Since many people run the flame effect without the heater for ambiance year-round, the quality and variety of the flame matter. Look for adjustable flame colors (usually 3 to 9), multiple brightness levels, and the ability to change the fuel bed (logs, crystals, driftwood). The Westinghouse offers 144 total color combinations, which is the broadest range in this lineup. A few models, like the LegendFlame, also include a crackling sound effect that can be turned on or off to make the fire feel more real.

In‑Depth Reviews
1. Touchstone Sideline Elite Smart 50” WiFi-Enabled Electric Fireplace
The premium in-wall unit with 60 color combinations and a smart thermostat that remembers your settings.
If you want the full custom look — a fireplace that sits recessed into your wall with only a slim black frame showing — the Touchstone Sideline Elite is designed specifically for that. It measures 5.5 inches deep, so it fits inside a standard wall cavity, and it comes with a full log set, driftwood, and crystals so you can swap the look of the fuel bed depending on your mood. The flames use 6 color options and 10 media color options that run independently, giving you 60 total color combinations, the most versatile setup in this lineup for changing the ambiance.
The smart features go beyond just a remote. This unit has a built-in thermostat adjustable from 68 to 88 degrees Fahrenheit with two heat settings (low and high). Buyers report that the WiFi app includes an 8-hour timer and a scheduler, and that it works with Alexa. One reviewer noted it is “quieter than the white noise we sleep with at night,” and another pointed out that the elite line offers a wider window than non-elite models, making the flame view more prominent. It also remembers your flame settings, so it turns on exactly how you left it if you use a wall switch. The catch is the premium cost and the requirement for a careful in-wall installation — this is not a unit you screw onto drywall in 20 minutes.
Unlike the LegendFlame, which weighs 62.61 pounds, the Touchstone is built for a fixed install and requires two people to move it, as one buyer mentioned. For a room where you want a permanent, high-end focal point with extensive color control and reliable heat, this is the pick.
Strengths
- 60 independent color combinations for flames and media bed
- Three flame speeds and five intensity settings for detailed ambiance control
- Smart thermostat (68-88°F) with WiFi app, scheduler, and Alexa compatibility
- Includes log set, driftwood, and crystals for flexible fuel bed styling
Trade-offs
- Premium price point — the most expensive model in this lineup
- Designed strictly for recessed installation; not a simple wall-mount option
- One buyer measured actual heat draw at 1200W, slightly below the advertised 1500W
- No realistic log-crackling sound effect, per some reviewer feedback
Reach for this if: you are doing a custom recessed build and want the deepest flame customization with smart-home scheduling.
Look elsewhere if: your budget is tighter or you need a simple wall-mount or freestanding setup.
2. PuraFlame Bernice 50 Inch Smart Linear Electric Fireplace
The clean-looking unit that hides its heater vents and gives you 9 flame colors plus voice control.
Most electric fireplaces have visible grilles on the top or front for heat output. The PuraFlame Bernice uses concealed heater vents and a 2-inch-wide extrusion aluminum trim to create a much cleaner, sleeker appearance. This design matters if you plan to mount a TV above it — the clean front panel makes the whole setup look like a single integrated piece. It measures 50 inches wide by 17.7 inches high by 6.3 inches deep, and it can be installed recessed in a wall, wall-mounted, or set up as a freestanding unit, giving you three placement options that most other models here don’t match.
The flame system offers 9 colors for both the flame and the fuel bed, plus a crackling sound effect. You control it via the included remote, the touch panel, or through the app and voice commands for Alexa and Google Assistant. One owner reported that the crackling sound is “a bit loud and there isn’t a volume control,” which is a specific annoyance if you want a very subtle background noise. The heating coverage is rated at 400 square feet with a thermostat adjustable from 60 to 84 degrees Fahrenheit. Unlike the Tangkula, which covers 500 sq ft, the PuraFlame sticks to the more common 400-sq-ft rating, but it does so with a more refined look.
At 48.9 pounds, it is lighter than the LegendFlame’s 62.61 pounds and easier for two people to manage during installation. The included driftwood and crystals let you change the fuel bed style, and the concealed vents mean no dust collects in obvious grilles.
Clean design that matters: The hidden vent system is the standout feature here — it makes the fireplace look like a smooth part of your wall, not a heater with a grate.
One specific drawback: The crackling sound has no adjustable volume, so you get one fixed loudness level or silence.
Go for it if: aesthetic cleanliness is your top priority and you want the flexibility to install it three different ways.
skip it if: you need very quiet crackling or want the absolute widest heating coverage at 500 sq ft.
3. Westinghouse 50 Inch Electric Fireplace Heater
A color-tweaker’s dream with 144 combinations, 5 brightness levels, and 5 flame speeds.
If you want to match the mood of the room precisely — a blue flame for a cool evening, a bright orange blaze for a party, or something in between — the Westinghouse lets you do that with the largest color palette here. It combines multiple flame colors and ember colors to create up to 144 total combinations, with 5 independent brightness levels and 5 distinct flame burning speeds. It includes both an interchangeable faux log set and crystal ember beds, so you can physically change the look of the firebox as well as the light color.
The unit is 50 inches wide by 15.75 inches tall, making it one of the shorter front-facing options, which can look sleeker under a TV. It fits into an opening of 49 inches by 15 inches by 6 inches if you recess it, or it can be wall-mounted. The built-in thermostat ranges from 62 to 82 degrees Fahrenheit, and the heat output is rated at 5110 BTUs — slightly higher than the 5000 BTU rating of the Tangkula and LegendFlame. One customer observed that “heat output is okay, not a primary heater,” which is a realistic expectation for any electric fireplace. The unit connects to WiFi and works with Alexa and Google Home, though one user highlighted the app supports “only one phone at a time.”
Unlike the Touchstone Sideline, which offers 60 color combinations, the Westinghouse gives you more than double the options if fine-tuning the color spectrum matters to you. The fan noise is reportedly very minimal, and owners mention the remote and app work well.
Why Pick This
- 144 total color combinations — the most flexible flame/ember customization in this lineup
- 5 independent brightness levels and 5 flame speeds for granular control
- 5110 BTU heat output, slightly higher than the 5000 BTU common among competitors
- Interchangeable log set and crystal ember bed included for physical decor flexibility
Check First
- App supports only one connected phone at a time, per user reports
- Requires 11.8 inches of clearance from the ceiling and anything mounted above
- Some users find the green flame color option unnecessary
- No Samsung SmartThings support, though it does connect to standard WiFi
Perfect if: you enjoy changing the flame color and speed frequently to match different events or moods.
Not ideal if: you want a deep recessed install with a very narrow frame — the Westinghouse is taller than some competitors and has a distinct front-facing grille.
4. LegendFlame 50″ W Austin in Wall Recessed & Wall Mounted Electric Fireplace
The heavy-duty heater that one buyer says keeps a 2000-square-foot Florida home warm without central heat.
The LegendFlame Austin stands out for its sheer build and heat output claims. At 62.61 pounds, it is the heaviest unit in this lineup — noticeably heavier than the Mystflame’s 44 pounds. That extra weight comes from a solid steel body and a deeper construction. One verified buyer stated that it “heats 2000+ sq ft home in Florida winter without central heating,” which is a far higher coverage claim than the official 400-square-foot rating. While fireplaces are supplementary heat, this unit appears to push more warm air than most in this class.
The firebox includes a log set, crystal stones, glass chips, and pumice, giving you four different media options to arrange behind the glass. The LED flame offers multiple colors and 5 brightness settings, plus a crackling sound effect. The heat is adjustable between a low 750W and a high 1500W setting, and the thermostat and countdown timer are included. The unit is smart-enabled via the Tuya app and works with Alexa and Google voice control, which the Tangkula lacks. However, the chamber depth is 5 inches, which is slightly shallower than the Mystflame’s 5.51-inch depth — and at 18.91 inches tall, it is the tallest unit here, which might affect how it fits under a TV or in a specific wall frame.
Buyers also note that positioning the fake wood and rocks behind the glass can be a bit tricky due to the interior layout, but once set, the effect is described as looking “better than k showroom units.” If your priority is substantial heat output in a durable, feature-heavy unit, this is the one to look at.
Real-world power: One owner’s experience heating a large home suggests this unit performs beyond its 400-sq-ft spec when you need serious supplemental warmth.
Size consideration: At just over 18.9 inches tall, it is the tallest 50-inch model here — measure your opening carefully before buying.
Pick it if: you want a heavy, solidly-built unit that customers note delivers surprisingly strong heat for a large space.
Think twice if: you are short on vertical space under a built-in shelf or TV — the height may be a tight fit.
5. 50 Inch Slim Electric Fireplace, Recessed in‑Wall or Wall Mounted, Ultra‑Narrow Frame (Mystflame)
A lightweight 44-pound unit that buyers install in minutes with a slide-in fit and simple controls.
If you want an electric fireplace that looks modern and goes up fast without a complicated project, the Mystflame ultra-slim frame model is built for that. At 44 pounds, it is substantially lighter than the LegendFlame’s 62.61 pounds — which makes solo installation much easier. The overall dimensions are 50 inches wide by 5.51 inches deep by 17.72 inches high, with a recessed insert size of 49.2 inches by 16.9 inches by 5.5 inches. Reviewers point out a simple “slide-in install” process, and the ultra-narrow bezel helps the flames stand out visually.
The flame effects offer 3 flame colors and 3 top accent light colors. It includes faux fire logs and clear crystals that you can mix and match. The thermostat is adjustable from 71 to 99 degrees Fahrenheit. One reviewer pointed out that it comes with “app, remote, and button controls; multiple color combos; real fire sound with 3 volume levels,” and another noted that the simulated flame colors are just okay and the sound quality is low. The customer service is frequently praised, with one buyer saying a failed light bar was replaced free after troubleshooting.
Unlike the PuraFlame, which has hidden vents, the Mystflame has front vents that allow safe installation under a TV if you follow the recommended clearances. The 1-to-9-hour timer gives you flexibility for falling asleep without worry. For a straightforward, light, and well-supported unit, this is a strong contender.
Pros
- Lightest model at 44 pounds — easy to handle and install alone or with one person
- 5100 BTU heat output, slightly hotter than the 5000 BTU common models
- App, remote, and panel controls with a real fire sound effect at 3 volume levels
- Excellent customer service according to multiple buyers
Cons
- Only 3 flame colors and 3 accent light colors — less variety than the Westinghouse or Touchstone
- Simulated flame quality and sound quality are described as just okay by some owners
- WiFi connection to the app can be hit or miss per one reviewer’s experience
- Remote may arrive damaged in transit, as one buyer experienced
Best for: someone who wants a simple, lightweight install with reliable customer support and good-enough flame effects.
Not for: you if having 9 or 144 flame color options is important to your decor scheme.
6. Tangkula 50 Inches Electric Fireplace Inserts
The budget-friendly pick that covers 500 square feet of heat and offers three installation styles.
Its 5000 BTU quartz heater can run at 750W or 1500W, with a thermostat adjustable from 62 to 82 degrees Fahrenheit. The fan operates at ≤35dB, which buyers describe as “very low fan noise” and easy to ignore while you sleep or watch TV. The unit can be recessed into the wall, mounted on the wall surface, or placed as a freestanding unit using the included stand feet — the same triple-installation flexibility as the PuraFlame.
The flame viewing area is larger than many competitors: Tangkula says its screen takes up 80% of the fireplace front, compared to a typical 60%. That means more visible flame in a wider view. It offers 9 flame colors and 5 brightness levels, all controllable from the panel or the remote. The unit includes plastic crystals (which one reviewer called “heavy-looking”) and fixed-arrangement faux logs that some found “cheesy.” The chamber depth is 5.5 inches, and the overall dimensions are 50 inches wide by 5.6 inches deep by 17.7 inches high, making it very similar in profile to the Mystflame. At about 63.7 pounds (based on the 28.89 kg weight), it is roughly equivalent to the LegendFlame in heft.
One important safety note from the reviews: the unit has an “auto shut-off after 30 min if timer not set (1-8 hrs),” and it automatically powers down if internal components reach 203 degrees Fahrenheit. It is ETL certified for extra safety. The lack of smart-home voice control is the main trade-off at this price point — unlike the Westinghouse or PuraFlame, there is no app or Alexa integration.
Room-warming champion: With a rated coverage of 500 sq ft, this claims to heat the largest area of any 50-inch model here — great for an open living space.
Aesthetic note: The faux logs are fixed in place and the crystals are plastic, which some buyers felt did not look as premium as the glass or stone options in pricier models.
Grab it if: your priority is maximum heating coverage and low noise on a limited budget without smart-home needs.
Pass if: you want voice control, a more realistic fuel bed, or a slimmer profile for a custom recessed build.
Understanding the Specs
BTU (British Thermal Units) and Room Coverage
BTU is the standard measurement for heat output in electric fireplaces. The models here range from 5000 to 5110 BTUs. This level of heat is considered supplemental — it takes the chill off a room or warms a small-to-medium living space. A general rule is that 5000 BTUs can effectively heat about 400 to 500 square feet depending on insulation and ceiling height. The Tangkula claims 500 sq ft, while most other units here are rated at 400 sq ft. If you have an open-concept floor plan or a drafty room, you will likely need your central heating to help out on very cold days.
Chamber Depth and Installation Fit
The chamber depth refers to how deep the fireplace insert is — the part that goes into your wall cavity. Most 50-inch models here have a depth between 5 inches and 6.3 inches. Standard US wall studs are typically 3.5 inches deep, so you may need to build out your wall framing to accommodate a 5.5-inch-deep unit. The LegendFlame has a chamber depth of 5 inches and an overall depth of 5.78 inches, while the PuraFlame is deeper at 6.3 inches overall. Always measure your rough opening before buying, and factor in the need for clearance around the unit for airflow.
