Quick Answer: Dimplex’s IgniteXL 50” ($2,689.99-$2,824.99 across current Home Depot, Walmart, and Dimplex price-list listings) is this site’s flame-realism benchmark, and per Dimplex’s own sell sheet it also hides a genuine 240V heat-boost to 2,500W/8,530 BTU — a spec this site’s own 220V guide hadn’t credited it with before. Amantii’s Symmetry Bespoke 60” ($3,399, list $4,593.24) stays flat at 1,500W no matter the price, but it’s been built for indoor-or-covered-outdoor flexibility from day one and keeps its full 5-year warranty in either setting, while Dimplex’s warranty drops to 1 year outdoors. Both brands now clear the “can it go on a covered patio” bar; they just handle the fine print very differently.
Dimplex and Amantii already anchor opposite ends of this site’s “Vs. Dimplex” bottom lines in nearly every other brand roundup — Dimplex as the realism standard every comparison measures against, Amantii as the brand with the most outdoor flexibility — but the two have never been placed directly side by side. Researching this comparison also surfaced a genuinely new finding: the IgniteXL’s own manufacturer sell sheet lists a 240V mode this site’s dedicated 220V/240V buying guide never counted it among.

A global heating conglomerate vs. a Canadian two-brand specialist
The size difference behind these two brands is bigger than most shoppers assume. Dimplex operates under Glen Dimplex Group, a privately held Irish conglomerate founded by the Naughton family that owns more than 30 companies worldwide, including the Cadet electric-heating brand in North America, per Glen Dimplex’s own corporate materials. Its North American fireplace arm, Glen Dimplex Americas, is headquartered in Cambridge, Ontario, and also makes the Faber, Opti-Myst, and Nectre brands. Amantii, by contrast, is a much smaller, privately held manufacturer based in Vancouver, British Columbia, with one close sister brand, the gas-focused Sierra Flame — retailer profiles describe the two brands together as having nearly four decades of combined industry experience. A Dimplex warranty claim runs through a multinational group with dozens of other product lines; an Amantii claim runs through a focused two-brand Canadian operation.
Heat: this is where Dimplex quietly catches up
Every brand comparison on this site has treated the standard 1,500W/5,000 BTU heater as the ceiling for anything that isn’t the SimpliFire Scion, Dimplex’s own BF Deluxe insert, or the Napoleon Astound. Checking Dimplex’s own IgniteXL sell sheet for this comparison turned up a real exception: the IgniteXL 50” runs 1,500W/5,118 BTU on a standard 120V circuit, the same as nearly everything else on this site, but it can also be hardwired to a dedicated 240V circuit for 2,500W/8,530 BTU, per Dimplex’s own published specs. That’s a genuine heat-boost path this site’s own electric fireplace 220V/240V guide hadn’t previously credited the IgniteXL with. Amantii has no equivalent at any price — the Symmetry Bespoke and every other model in its lineup stays capped at the standard 1,500W element regardless of how much the finish or install flexibility costs.
Dimplex IgniteXL 50" Built-in Linear Electric Fireplace
- 1,500W/5,118 BTU on a standard 120V circuit, stepping up to 2,500W/8,530 BTU when hardwired to a dedicated 240V circuit, per Dimplex's own sell sheet.
- Dimplex's patented layered flame technology — the realism benchmark every other brand on this site gets measured against.
- Certified for covered-outdoor installation since November 2025, though the warranty drops from 5 years indoors to 1 year outdoors either way.

Outdoor flexibility and warranty: a closer race than it used to be
Until Dimplex’s November 2025 certification update, Amantii’s Bespoke line was the clearer outdoor pick on this site — rated for indoor or covered-outdoor installation on the same unit from the start, while Dimplex’s Ignite series was still indoor-only in most older guides. That gap has narrowed: the IgniteXL, Ignite Bold, and Ignite Evolve are now all certified for covered-outdoor installation too, per Dimplex’s own warranty certificate. The difference that’s left is what happens to coverage once the unit actually goes outside. Dimplex’s 5-year limited warranty drops to just 1 year the moment the IgniteXL is installed outdoors. Amantii’s Symmetry Bespoke carries a flat 5-year warranty whether it’s installed indoors or on a covered patio, per Amantii’s own warranty document — the same model, the same coverage, regardless of where it ends up.
Amantii Symmetry Bespoke 60" Electric Fireplace
- Rated for indoor or covered-outdoor installation on the same unit since launch, per Flame Authority's own spec listing.
- 5-year limited warranty regardless of indoor or outdoor install, per Amantii's own warranty document — unlike Dimplex's 5-year-to-1-year outdoor drop.
- 1,500W/5,000 BTU heater (750W on low) with no 240V heat-boost option, the same flat output as every other Amantii wall and linear model. Amantii's only 240V-capable unit is the freestanding Lynwood cast-iron stove, covered in our best electric fireplace stove guide.
Price: Dimplex is actually the cheaper flagship here
The IgniteXL 50” currently runs $2,689.99 at Home Depot and $2,824.99 at Walmart and on Dimplex’s own retail price list — notably lower than the $3,049.99 figure this site’s other Dimplex coverage has used, a real price drop worth flagging on its own. Amantii’s Symmetry Bespoke 60” runs $3,399 at Flame Authority, down from a $4,593.24 list price. That makes Dimplex’s realism-benchmark flagship roughly $575-$700 cheaper than Amantii’s full-frame flagship at current prices, even before counting the IgniteXL’s optional heat-boost — though the two aren’t an exact size match, since Amantii’s Bespoke line doesn’t come in a 50” size to compare directly.
Install options
Dimplex’s IgniteXL is a built-in linear unit designed to recess into a new wall opening or mount as a surface-mounted feature — see the best Dimplex electric fireplace guide for the Sierra, Multi-Fire Slim, and Revillusion insert alternatives if the IgniteXL’s size or depth doesn’t fit. Amantii’s Bespoke tier is sold as a standalone full-frame unit rather than a complete mantel package — see the best Amantii electric fireplace guide for the Tru View Bespoke 3-sided option and the budget FS-26-922 freestanding stove.
The bottom line
Choose the Dimplex IgniteXL if flame realism is the deciding factor and the optional 240V heat-boost might actually get used — it’s also the cheaper flagship at current prices. Choose Amantii’s Symmetry Bespoke if the fireplace’s final location (indoor now, covered patio later) is genuinely uncertain and a consistent 5-year warranty matters more than saving on price.
