The affordable 60-inch that packs a surprising number of color and timer options.

You get 12 different flame colors and five brightness levels here, which beats many mid-range units on color variety alone. The 750W/1200W dual-mode heater covers up to 400 square feet, and the 8-hour timer lets you low-maintenance at bedtime. Buyers report that assembly is easy and the unit does not protrude far from the wall, leaving the top surface usable for decor.

Where this Tangkula stands out is the weight — at 41 pounds it is 8.5 pounds lighter than the Silonn 50-inch model, making it much easier to handle during installation. The 60-inch width gives you a wide flame view without the heavy 117-pound frame of the HIRESC 60-inch. The included remote works from up to 20 feet away for flame, heat, and timer adjustments.

The main trade-off: the faux logs lack the realism you would get from a premium unit like the Touchstone. Multiple owners mention the logs look a bit plastic compared to the flames themselves. If your priority is maximum realism over budget, that is worth factoring in.

A smart insert that adapts from a corner unit to a single-sided linear fire.

The defining trick here is the 1-to-3-sided configuration. You can install it as a full three-sided wrap-around, set it for a corner view, or run it as a single-sided linear fireplace — the same unit does all three by adjusting the glass panels. That flexibility is rare in this category and saves you from buying a different model if you rearrange the room later.

Smart integration includes both Alexa and Google Assistant, plus a dual-flame color design that combines orange with eight other accent colors. The fuel bed also lights up in eight colors. Buyers describe the flames as “very realistic” with sound that crackles like a real fire. At a 10.2-inch depth, this unit is 39% deeper than the 7.36-inch Silonn 50-inch, meaning you need more cavity space behind the wall.

The one-year limited warranty is standard for the price tier, and the unit is CSA certified. One reviewer noted the only thing missing is a glowing ember effect on the logs, which would push the realism even higher.

A 50-inch smart unit that brings 15-color flames and built-in crackling sound.

This Silonn model packs 15 flame colors, five brightness levels, and three flame speed settings — giving you more color variety than the 12-color Tangkula. The 5110 BTU heater (about 1500W) covers rooms up to 400 square feet, and the adjustable thermostat ranges from 68°F to 88°F. Customers note decent heat output and quiet operation, with the remote and app control working smoothly after initial WiFi pairing.

One feature that stands out is the built-in speaker that simulates the crackling sound of burning wood. Combined with the 1:1 replicated resin faux logs, the audio-visual mix creates a campfire atmosphere that the silent units cannot match. The LED top lights, flames, and crystal fire bed each have 15 independent color options, so you can mix and match the look.

At 49.5 pounds this unit is heavier than the Tangkula 60-inch by about 8.5 pounds, but the 7.36-inch depth is shallow enough for most standard wall cavities. The installation is flexible: wall mount, recessed, or freestanding.

A freestanding 50-inch unit with a white mantel, ideal for renters who cannot recess.

Unlike most inserts that require recessing into a wall, this Maxhonor model comes as a complete mantel package in a white painted finish. The 5.1-inch solid base keeps it stable on the floor, and the three-sided tempered glass gives the wrap-around view without any carpentry work. Assembly takes about an hour, and reviewers point out the instructions are clear enough for one person.

The flame effects come in 12 colors with five brightness levels, and the 1500W/750W heater adjusts from 64°F to 82°F, covering up to 400 square feet. The 1-to-8-hour timer is useful for energy saving overnight. Shoppers say the flame is not hyper-realistic but creates a cozy ambiance, and the 50-inch size works well under a TV without overwhelming the wall.

The main limit here is the engineered wood and metal construction — it is not as heavy-duty as a recessed-only metal unit, and the mantel adds bulk (52.2 inches wide, 32.9 inches tall). That said, for anyone who cannot cut into drywall, this is the only plug-and-play mantel option in the list.

A 60-inch smart insert with 251 flame colors and independent control of three light zones.

The headline number here is 251 RGB flame colors — you mix red, green, and blue LEDs to dial in anything from a soft amber to an electric blue. That versatility goes beyond any other model in this lineup. The Smart Life app lets you control flames, ember bed, and downlight independently, so you can have blue flames with a warm ember glow and cool accent lighting all at once.

The 5118 BTU heater (1500W high / 750W low) covers 400 square feet with an adjustable thermostat from 62°F to 82°F. Buyers praise the heat output and how quiet the fan runs. The 60-inch width fits standard fireplace openings, and the 11-inch depth requires a deeper cavity.

ETL certification and cool-to-touch glass add safety confidence. The unit supports both plug-in and hardwired connections, giving you flexibility during the build.

A 71-inch version of the RGB flagship, balancing width and weight better than the 80-inch.

This 70-inch model (actual dimensions 71 inches wide) gives you the same 251 RGB flame colors, 5118 BTU heater, and Smart Life app control as the 60-inch HIRESC but stretches the flame view 11 inches wider. The 131.6-pound weight is about 14.6 pounds heavier than the 60-inch — a manageable increase for noticeably more screen real estate.

The 11-inch depth, 400-square-foot heating coverage, and adjustable thermostat (62°F to 82°F) are identical to the 60-inch and 80-inch siblings, so the trade-off is purely width versus weight. Buyers report that even at this size the unit runs quietly and the heater warms a large living room effectively during winter. The ETL certification and cool-to-touch glass are the same safety features as the smaller version.

If 60 inches feels tight for your wall but 80 inches is overkill, this 70-inch slot hits a balance. The included crystals and log set give you two fuel-bed looks to switch between.

The big brother of the Legend Flame 59-inch, offering the same configurable view at 72 inches.

This is the larger version of the Legend Flame smart insert (product #2), scaled up to a 72-inch overall width with a 70.9-inch visible fire area. It keeps the same 1-to-3-sided viewing configuration, so you can run it as a full three-sided wrap, a corner install, or a single-sided linear display. The dual-flame color design mixes orange with eight other colors, and the fuel bed has eight color options.

At 105.4 pounds, it is about 11.6 pounds lighter than the 71-inch HIRESC model despite being an inch wider — a nice advantage for handling during installation. The 5.5-inch chamber depth is notably shallow, making it one of the best options for standard 2×4 walls where a deeper unit like the Legend Flame 59-inch (10.2 inches) would not fit. Alexa and Google Assistant integration are built in.

The one-year limited warranty covers defects, and buyers consistently describe the flames as realistic with convincing crackle sound. The only repeated critique is the lack of a glowing ember effect on the logs.

An 80-inch RGB powerhouse that commands the wall with a 146.1-pound frame.

This is the widest HIRESC model before the massive 100-inch version, and at 80 inches of flame view it will dominate a large entertainment wall or great room. The 251 RGB colors, independent flame/ember/downlight controls, and Smart Life app are the same as the 60-inch and 70-inch siblings, so you get no extra features — just more horizontal flame spread.

The 146.1-pound weight is the heaviest in the HIRESC lineup outside the 100-inch, so you definitely need a helper and a sturdy wall frame. The 5118 BTU heater still covers 400 square feet, and the adjustable thermostat runs from 62°F to 82°F. Buyers rave about the heat output and quiet fan, noting the unit feels solid and well-constructed. ETL certification and cool-to-touch glass provide the usual safety safeguards.

The 11-inch depth remains unchanged from the smaller HIRESC models. The installation kit includes crystals and a log set for two distinct fuel bed looks.

The 50-inch that focuses on flame realism and premium media over raw color count.

Where other units brag about 251 colors, the Touchstone Sideline Infinity Pro keeps it to six realistic flame colors and puts the engineering into how the flames look and move. The ember bed has 13 color options with four predefined levels plus a pulsating setting, and the included media — painted crushed glass crystals and realistic driftwood — looks more authentic than the standard resin logs in lower-priced models, according to reviewers. The 13-color downlighting adds another layer of ambient control.

The 1500W/750W heater covers up to 400 square feet with an adjustable thermostat from 68°F to 88°F. The built-in crackle speaker adds the wood-burning sound effect. Owners mention the flames look very realistic and the Touchstone is a clear step up from cheaper units. The WiFi app and Alexa integration work reliably, and the 9.25-inch depth fits into most standard wall cavities.

One overlooked detail: there is no panel lock when the unit is off, meaning children could accidentally activate the controls. That is a small safety gap that keeps a few reviewers from giving a perfect score.

The full-wall statement: a 100-inch-wide insert that turns an entire wall into a flame display.

At 100 inches wide, this HIRESC model is the largest 3-sided insert in the lineup and essentially turns your wall into a linear fire feature. The 251 RGB color engine, Smart Life app, and 5118 BTU heater are the same as the smaller HIRESC units, but the 100-inch frame demands serious planning — you need a wall opening that can accommodate the width and the 11-inch depth.

The thermostat range here is wider than the other HIRESC models, adjustable from 50°F to 99°F, giving you more fine-tuning at both ends. The programmable timer also extends to 12 hours (versus 8 hours on the smaller versions), which is useful for overnight heating schedules. Customers note that even at this scale the unit runs quietly and the heat output is substantial enough for large open-plan spaces.

The metal construction feels solid, and the included crystals and log set give you two fuel-bed looks. The weight is not listed in the official specs, but given the 80-inch model is 146.1 pounds, expect the 100-inch to be significantly heavier — two strong helpers and proper structural support are mandatory.
