Quick Answer: Dimplex’s IgniteXL 50” ($2,689.99-$2,824.99 across current Home Depot, Walmart, and Dimplex price-list listings) stays this site’s flame-realism benchmark, carries the longer indoor warranty, and is the only one of the two rated for covered-outdoor installation. SimpliFire’s Scion 55” ($2,579, list $3,439) costs slightly less, has a bigger 240V heat-boost ceiling (2,800W vs. the IgniteXL’s 2,500W), and documents full Amazon Alexa and Google Home voice control — a feature Dimplex doesn’t offer on the IgniteXL at any price. Buy Dimplex for realism, warranty, and outdoor flexibility; buy SimpliFire for voice control and a slightly bigger heat-boost ceiling.
Dimplex and SimpliFire sit in the same premium tier on this site — both show up repeatedly in the high-end and 240V-heat-boost guides — but have never been compared directly. SimpliFire’s own product page already credits the Scion with Alexa and Google Home support, the same voice-assistant gap this site found when comparing Dimplex against Napoleon. Here it shows up again against a second brand, alongside a genuinely closer heat-output race than that earlier comparison.

Two multi-brand portfolio companies, different scale
Neither Dimplex nor SimpliFire is a single independent fireplace maker — both operate inside larger portfolio companies, just at very different scale. Dimplex sits 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 and fireplace siblings Faber, Opti-Myst, and Nectre, per Glen Dimplex’s own corporate materials. SimpliFire is made by Hearth & Home Technologies, a US manufacturer that also owns the Majestic and Monessen fireplace brands — a smaller, single-country portfolio compared to Glen Dimplex’s global, multi-industry reach. A SimpliFire warranty claim stays inside one US hearth-products company; a Dimplex claim runs through a group that also makes space heaters and HVAC equipment on a different continent.
The real gap: SimpliFire’s flagship talks to Alexa, Dimplex’s doesn’t
This site already found this gap once, comparing Dimplex against Napoleon — and it shows up again here. SimpliFire’s own product listing for the Scion documents app control plus full Amazon Alexa and Google Home voice commands, alongside nine adjustable flame colors and 13 ember-bed colors, more smart-home integration than any other SimpliFire model. Dimplex’s IgniteXL and its pricier Ignite Evolve sibling only document app-based control over Bluetooth or WiFi through the Flame Connect app — no Alexa, no Google Home, confirmed across multiple current retailer and manufacturer sources. At a price that’s actually slightly lower than the IgniteXL’s, the Scion is the more connected of the two.
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.
- Certified for covered-outdoor installation since November 2025 — but the warranty drops from 5 years indoors to 1 year the moment it's installed outside.
- Controlled via the Flame Connect app over Bluetooth/WiFi or the included remote — no Alexa or Google Home support documented anywhere by Dimplex.

Price and heat-boost ceiling both lean slightly toward SimpliFire
SimpliFire’s Scion 55” lists at $3,439 with current retailer pricing around $2,579 at Electric Fireplaces Depot — around $100-$250 cheaper than the IgniteXL’s $2,689.99-$2,824.99, despite being 5 inches wider. The Scion’s 240V heat-boost mode also edges out the IgniteXL on raw output: 2,800W and up to 800 sq ft of coverage, versus the IgniteXL’s 2,500W/8,530 BTU. Both upgrades require an electrician to install a dedicated circuit — this site’s electric fireplace 220V guide covers the ~$650-$700 cost either way. The gap isn’t dramatic on either price or wattage, but it’s consistently in SimpliFire’s favor on both fronts.
SimpliFire Scion 55" Built-In Linear Electric Fireplace
- Full Amazon Alexa and Google Home voice control plus nine flame colors and 13 ember-bed colors, per SimpliFire's own product listing — a feature Dimplex doesn't document on the IgniteXL at any price.
- Hardwired to a dedicated 240V circuit, output doubles from 1,400W to 2,800W and up to 800 sq ft of real coverage, per SimpliFire's own spec sheet.
- 2-year flat warranty, well short of the IgniteXL's 5-year indoor term — and the Scion carries no outdoor rating at all, so it's an indoors-only unit.
Warranty and outdoor use both favor Dimplex
Here the IgniteXL pulls ahead decisively. Dimplex’s 5-year indoor warranty more than doubles SimpliFire’s flat 2-year term, per each brand’s own warranty documentation. Outdoors, the gap narrows but still favors Dimplex: the IgniteXL’s warranty drops to 1 year once installed outside, but it’s still covered, where the Scion has no outdoor rating to even consider — it’s sold and documented strictly as an indoor unit. Anyone weighing a covered patio or three-season room install only has one of these two brands to choose from.
The bottom line
Choose the Dimplex IgniteXL if flame realism, the longer warranty, or the option to install outdoors matters most — it remains this site’s realism benchmark and the only one of the two rated for covered-outdoor use. Choose SimpliFire’s Scion if Alexa or Google Home voice control, a slightly lower price, or squeezing out a bit more heat-boost wattage matters more than warranty length or outdoor flexibility.
