If you've been comparing built-in linear electric fireplaces and the SimpliFire Allusion electric fireplace and Amantii Panorama Slim are both on your shortlist, you're looking at two genuinely capable units in the same general form factor. Both are slim built-ins designed for recessed wall installation, both produce roughly 5,000 BTU of supplemental heat, and both offer multi-color flame effects with remote control. But they diverge meaningfully on price, installation flexibility, flame technology, and smart-home capability. Here's what the comparison actually looks like across the categories that matter.
The built-in electric fireplace category is one of the fastest-growing segments in the hearth market, and these two models sit near the top of the built-in linear segment -- one a value-oriented performer, the other a premium smart unit with outdoor credentials. Neither is the right answer for everyone.
The SimpliFire Allusion Platinum starts at $1,559 for the 50-inch model, $1,879 for the 60-inch, and $2,289 for the 72-inch. The Amantii Panorama Slim starts at $2,499 for the 50-inch and $2,799 for the 60-inch.
At the 50-inch size, the Allusion Platinum is $940 less. At 60 inches, the gap is $920. Neither fireplace carries meaningful hidden costs that shift the comparison: both include decorative media, a remote, and (for the Amantii) a black steel surround. The SimpliFire offers optional build-out and wall bracket kits sold separately, which are relevant for surface-mount installations but aren't required for standard built-in use.
If budget is a primary constraint, the Allusion Platinum has a consistent and substantial pricing advantage at every available size.
Both fireplaces draw 1,500 watts at full heat output on standard 120V household current. The Allusion Platinum pulls up to 15 amps; the Amantii Panorama Slim draws 12.5 amps. At average U.S. electricity rates around $0.16/kWh, running either unit at full output for four hours per day adds approximately $35 to $40 per month to your electricity bill.
Both include two-stage heaters that let you run at lower wattage for ambiance-only or reduced-intensity use, cutting that operating cost further. Neither requires a gas line, combustion venting, or annual inspection. From a running-cost standpoint, these two fireplaces are effectively identical. The decision comes down to capital cost and features, not utility expense.
The SimpliFire Allusion Platinum is rated at 5,000 BTU and is appropriate for supplemental zone heating in spaces up to approximately 400 square feet. The Amantii Panorama Slim is rated at 4,800 BTU with coverage guidance in the 400 to 500 square foot range depending on the source.
One functional difference worth noting: the Allusion Platinum pushes heat from the front of the unit, which is standard for electric fireplaces in this category. The Amantii Panorama Slim positions its heater and fan at the top of the unit, with the glass angled slightly backward so heat cascades down over the front face. In typical room installations the practical difference is minor, but the Amantii's top-vent approach may distribute heat slightly more evenly across the wall surface.
Neither unit is a primary heat source. Both are appropriate for supplemental zone heating, and both will feel comparable in everyday use.
Both fireplaces are ventless electric units. No flue, no gas line, no CO venting, and no combustion permits required. Installation is primarily a carpentry and electrical task in both cases.
Where they differ is in installation flexibility.
The SimpliFire Allusion Platinum is designed for 2x6 wall construction and can be installed fully recessed (flush with the wall face) or surface-mounted using an optional wall bracket or build-out kit. The unit depth is 5-5/8 inches, with a 6-inch framing depth required for a full recess. This dual-mode capability gives the Allusion Platinum meaningful adaptability -- it can go into a finished wall or be surface-applied with the right accessories, without requiring a full remodel.
The Amantii Panorama Slim is 6-3/4 inches deep and is designed specifically for built-in recessed installation. It is not designed for surface wall-mount. It does come with a black steel surround that provides a finished framed appearance without requiring tile or drywall to meet the glass. Notably, the Panorama Slim is rated for both indoor and covered outdoor installation -- a distinction the SimpliFire does not share.
If you're planning a covered patio or outdoor installation, the Amantii Panorama Slim is the only option between these two. For flexible indoor installations that may include surface mounting, the SimpliFire has the edge.
Both fireplaces are LED-based electric units with no combustion, no ash, and no cleaning requirements beyond occasional glass and media care. The electric heating elements are solid-state and sealed, making both units low-maintenance by design. Neither requires annual servicing or inspections.
The SimpliFire Allusion Platinum is CSA certified. The Amantii Panorama Slim is UL Listed. Both certifications confirm the units have been tested to applicable North American electrical safety standards.
The only recurring maintenance consideration is decorative media over time. Both units include glass or crystal media that can shift during shipping or over years of use. Replacement media is available for both brands through the manufacturer and retailers.
The SimpliFire Allusion Platinum offers four distinct flame themes with 13 ember bed color options. The viewing area on the 50-inch model is 48 inches wide by 15 inches tall. Controls include a multifunction remote and onboard touch panel. There is no Wi-Fi or smartphone app.
The Amantii Panorama Slim has a multi-color flame effect (yellow, orange, and red) with 13 canopy and ember lighting color options. The viewing area is notably lower-profile: 45.25 inches wide by 12 inches tall on the 50-inch model. Controls include a remote plus the Amantii app via Wi-Fi -- allowing full control from a smartphone anywhere in the home.
The taller flame window on the SimpliFire gives it a more dramatic visual presence on the wall. The Amantii's lower-profile flame suits contemporary designs where a wide, thin band of flame is the aesthetic goal. App control on the Amantii is a genuine functional differentiator for tech-forward setups or whole-home automation integration.
The SimpliFire Allusion Platinum is the better fit if: you're keeping the budget under $1,600 at the 50-inch size, you need the option to surface-mount or use a build-out kit rather than cut fully into the wall, or you prefer a taller and more dramatic flame viewing area. It's also the right choice for strictly indoor applications where app control isn't a priority.
The Amantii Panorama Slim is the better fit if: smartphone app control matters to your project, you're planning a covered outdoor installation, you want a wide frameless glass-to-wall finish with the included steel surround, or you're comfortable paying a premium for a unit with built-in Wi-Fi.
For a standard indoor living room installation with no smart-home integration requirement, the SimpliFire Allusion Platinum delivers comparable performance at a meaningfully lower price. The Amantii earns its premium in specific scenarios -- outdoor use, app-driven control, or design contexts where its lower-profile flame window is the intended look.

The SimpliFire Allusion Platinum requires a 6-inch framing depth for full recess into a 2x6 wall. The Amantii Panorama Slim is 6-3/4 inches deep and requires a wall cavity to match its depth for built-in installation. If full recess isn't possible, the SimpliFire can also be surface-mounted with optional accessories; the Amantii cannot.
