Quick Answer: Dimplex’s strongest overall pick remains the IgniteXL 50” ($3,049.99, list $3,964.99, per Dimplex’s own store) for its patented layered flame — the realism benchmark this whole site measures every brand against. For a lower price with genuine installation flexibility, the Sierra 48” ($849.99, per AMS Fireplace) can be recessed, wall-mounted, or set on a tabletop stand, and ships with three swappable media beds. The ultra-thin Multi-Fire Slim 60” ($2,099.99, down from $2,309.99 per Royal Fire Pits) fits flush in a 4-inch wall cavity, and the Revillusion 24” insert ($1,499.99) is the pick for retrofitting an existing firebox. All four run a 1,400-1,500W heater, but Dimplex’s own spec sheets rate the Sierra and Multi-Fire Slim for up to 1,000 sq ft versus the IgniteXL’s ~400 sq ft — a real inconsistency worth knowing before you size a room off any single spec sheet.
Dimplex is the flame-realism standard this site keeps coming back to — every brand roundup we’ve published, from Napoleon to Real Flame to SimpliFire, gets measured against the Dimplex benchmark at some point. But “Dimplex” isn’t one fireplace; it’s several distinct product lines built for different installs and budgets. We compared four real Dimplex models across the four ways people actually shop this brand: best overall realism, best value with install flexibility, best ultra-thin flush-mount, and best firebox retrofit.

1. IgniteXL 50” — Best Overall / Most Realistic
Dimplex IgniteXL 50" Built-in Linear Electric Fireplace
- Dimplex's patented layered flame effect with a genuine ember bed — the realism benchmark this entire site compares every other brand's flame technology against.
- $3,049.99, down from a $3,964.99 list price, per Dimplex's own store — the same verified figure used across this site's other Dimplex coverage.
- 1,500W heater rated for roughly 400 sq ft, per this site's sizing canon — full plug-in heat despite the premium price tag buying realism, not extra warmth.

The IgniteXL is the pick if flame realism is the deciding factor and budget isn’t. It’s the same model this site’s most realistic electric fireplace guide ranks first overall, and the one every brand comparison on this site — Napoleon, Real Flame, SimpliFire, Amantii — gets measured against.
2. Sierra 48” — Best Value / Install Flexibility
Dimplex Sierra 48" Linear Electric Fireplace
- One unit, three install options, per Dimplex's own product spec — recess it into a wall, hang it like the site's other wall-mount picks, or set it on the included tabletop stand without any installation at all.
- Ships with three interchangeable media beds (crystals, logs, or pebbles) and touch-screen plus remote control, a wider media selection than most single-media inserts covered elsewhere on this site.
- Runs a 1,400W/4,777 BTU heater that Dimplex's own spec sheet, per AMS Fireplace's listing, rates for up to 1,000 sq ft — more than double the ~400 sq ft this site's sizing guide uses for the IgniteXL on similar wattage.
For a bedroom, den, or first Dimplex purchase where the IgniteXL’s price doesn’t make sense, the Sierra delivers real Dimplex build quality and touch-screen control at roughly a quarter of the flagship’s cost. Its install flexibility also makes it one of the few models on this site that works whether you end up renting or buying.
3. Multi-Fire Slim 60” — Best Ultra-Thin Flush-Mount
Dimplex Multi-Fire Slim 60" Electric Fireplace
- Just 4 inches deep, per Dimplex's own spec sheet — thin enough to recess flush into a standard 2x4-framed wall, closer to the R.W.Flame 36" covered in our electric fireplace dimensions guide than to the deeper IgniteXL.
- Controlled through Dimplex's Flame Connect app in addition to the included remote — app control this site has otherwise only seen on Touchstone's Sideline Elite and Napoleon's Stylus Cara Elite.
- $2,099.99, down from a $2,309.99 list price, per Royal Fire Pits' current listing; runs the standard 1,500W/5,000 BTU heater that Dimplex's own spec, per Electric Fireplaces Direct, rates for up to 1,000 sq ft.
The Multi-Fire Slim is the pick when wall depth is the constraint — a shallow closet wall, an RV or camper build like the ones in our best electric fireplace for RV guide, or any 2x4 partition wall that can’t fit the IgniteXL’s deeper housing.
4. Revillusion 24” — Best Firebox Retrofit
Dimplex Revillusion 24" Built-in Electric Firebox
- Dimplex's second realism-focused flame patent, distinct from the IgniteXL's layered-flame technology, built specifically to replace the visual of a real wood or gas firebox rather than sit on an open wall.
- $1,499.99 for the smallest 24" size, per Rocky Mountain Stove and matching this site's existing verified figure — smaller sizes exist for narrower firebox openings than the IgniteXL's minimum width.
- Drops into an existing masonry or prefab firebox opening, the same install category covered against Napoleon's Cineview and PuraFlame's Western insert in our best electric fireplace insert guide.
If you’re converting an existing wood-burning or gas firebox instead of building a new wall feature, the Revillusion is Dimplex’s direct answer — and the closest thing to the IgniteXL’s realism in an insert form factor. See our best Dimplex electric fireplace insert guide for how it stacks up against Dimplex’s other two firebox-retrofit lines, including a hardwired option with genuinely more heat.
Dimplex vs. the brands already on this site
- Vs. Touchstone: Touchstone remains the value leader for a straightforward linear wall-mount at a lower entry price — see our Dimplex vs Touchstone breakdown for the full realism-vs-value tradeoff.
- Vs. Napoleon and SimpliFire: Both brands’ premium lines (Napoleon’s Stylus Cara Elite, SimpliFire’s Scion) add smart control or a 240V heat boost, but neither matches the IgniteXL or Revillusion’s flame realism, per our existing Napoleon and SimpliFire roundups.
- Heat claims vary even within one brand — as covered above, Dimplex’s own Sierra and Multi-Fire Slim spec sheets claim up to 1,000 sq ft while the IgniteXL’s real-world rating sits closer to 400 sq ft on similar wattage. Don’t assume a brand name guarantees a consistent heat spec across its whole lineup; check the specific model.
The bottom line
For most buyers who want the flame realism Dimplex is known for, the IgniteXL 50” is still the strongest pick and the one worth the premium. Budget or renting? The Sierra 48” delivers real Dimplex quality and three install options for about a quarter of the price. Tight wall depth points to the Multi-Fire Slim, and retrofitting an existing firebox means the Revillusion is the more direct Dimplex option than any wall-mount here.
