Head to head · two different monopolies
Dimplex vs Napoleon
Each of these brands makes a product the rest of the category simply cannot. The useful question is not which brand is better, it is which of the two problems you actually have — the flame, or the wall.

Dimplex changes what the fire looks like; Napoleon changes what the opening can be. Dimplex owns two flame technologies nobody else has — Opti-Myst ultrasonic water vapor, the only electric flame with real three-dimensional volume, and Revillusion, a deep firebox with no visible light source. Napoleon owns two formats nobody else sells — the CLEARion, the only true see-through unit in general circulation and the only fireplace on this site rated above 1,500 watts, and the Allure Vertical, for a wall no linear panel fits. If your problem is that electric flames do not convince you, buy Dimplex. If your problem is the shape of the wall, buy Napoleon.
Two monopolies, and they are not the same kind
Most brand comparisons on this site come down to documentation and price, because most electric fireplaces are the same appliance in a different box. These two are the exception. Each one makes something the rest of the category genuinely cannot, which is why they are worth comparing at all — and the trap is assuming the two monopolies are competing for the same buyer.
Dimplex's monopoly is optical. Opti-Myst raises a cool mist from ordinary tap water with ultrasonic transducers and lights it from beneath, producing a flame that occupies real space and moves the way smoke moves. Revillusion solves the same problem a different way — depth, and a concealed light source. Both change what you are looking at. We take the mechanisms apart on flame technology explained.
Napoleon's monopoly is architectural. The CLEARion is a fireplace you can see through from one room into another. The Allure Vertical is a fire turned on its end. Neither is a better flame than a good linear panel — they are shapes that let a fireplace go where one otherwise could not. Nothing in the Dimplex catalog answers either.
The one place the 1,500 watt ceiling breaks
Every plug-in electric fireplace sold in the United States is capped at 1,500 watts by a standard 120 V circuit — about 5,118 BTU per hour — and that is true at every price and of both these brands. Here is what that costs to run:
| Usage | Hours | Heat on (1,500 W) | Flame only (~100 W) |
|---|---|---|---|
| One evening | 4 | $1.10 | $0.07 |
| A week of evenings | 28 | $7.70 | $0.51 |
| A month, 4 hrs a night | 120 | $33.01 | $2.20 |
| A 90-day winter, 4 hrs a night | 360 | $99.04 | $6.60 |
| Per hour | 1 | 27.5¢ | 1.8¢ |
The CLEARion is the only exception we have found in the whole category. Wired to 240 volts at 15 amps Napoleon rates it at 3,000 watts and up to 10,000 BTU per hour, because it carries two heaters that operate independently — one facing each room. That is genuinely twice the output of anything else here, and it is also the reason the unit is not a plug-in: a 240 V 15 A circuit is an electrician's job and most living rooms do not have one. On ordinary 120 V power it drops back into the same class as everything else. Do electric fireplaces actually heat a room? is the general version of this argument.
How we judged this
Because both brands sit at the premium end, the usual criteria — price, wattage, coverage — separate them barely at all. So we ranked on the four things that actually differ between them.
- What the brand can do that the other cannot. This is the whole comparison. Two optical monopolies against two architectural ones.
- What the manufacturer publishes. On a built-in, the rough opening is the number the project runs on. One of these brands prints a full rough-in framing table and the other prints nothing for its flagship.
- Where the range covers the price ladder. A brand that only exists above two thousand dollars is a different proposition from one with something at four hundred.
- Whether the headline figure survives contact with a real circuit. Napoleon's 10,000 BTU is real and conditional; the condition matters more than the number.
The comparison, line by line
| Dimplex | Napoleon | |
|---|---|---|
| What nobody else has | Opti-Myst water vapor; Revillusion concealed-source firebox | CLEARion true see-through; Allure Vertical tall format |
| The monopoly is | Optical — it changes the flame | Architectural — it changes the opening |
| Breaks the 1,500 W ceiling | No | Yes — CLEARion, 3,000 W at 240 V, up to 10,000 BTU/hr |
| Publishes a rough opening | Yes — full rough-in framing table for Revillusion | No rough opening published for the CLEARion 50 |
| Entry price in our catalog | A log set; then a steep jump | A vertical panel, with several steps above it |
| Where the range is thin | The middle — one older linear panel below the class wattage | The flame itself — good layered LED, nothing exotic |
| Needs an electrician | Only for the higher-voltage Revillusion rating | Yes, for the CLEARion's 240 V rating |
Where the price ladders diverge
This is the practical difference most buyers hit first. Napoleon's range steps up in reachable increments, from a vertical panel through a wall-hung unit and a linear to the see-throughs at the top. Dimplex has one genuinely affordable product — a Revillusion log set — and then jumps, with almost everything that makes the brand distinctive sitting at the top of the market.
That is not a criticism so much as a description of what each brand is for. Dimplex sells technology and charges for it. Napoleon sells formats across a ladder. If the budget is the binding constraint and neither monopoly is the reason you are here, the honest answer is that the best brands overall is a more useful page than this one.

So which one
- Ordinary electric flames do not convince you. Dimplex, and the decision is already made — nothing Napoleon sells changes the flame.
- You want a fireplace between two rooms. Napoleon, and there is no second option in the category.
- The wall is tall and narrow. Napoleon. Dimplex makes nothing that fits.
- You want the most heat an electric fireplace can produce. Napoleon's CLEARion on 240 V, and budget for the electrician. Otherwise both brands are capped like everyone else.
- You are framing it into joinery and want a number to build to. Dimplex, on the strength of the published rough-in.
- You want a fifty-inch linear panel for a normal wall. Neither, particularly. Both are premium answers to a question the mid-market answers well — see best electric fireplaces under $1,000.

#1 · When the flame is the problem
Dimplex Revillusion RBF30 30" Built-In Firebox
A deep firebox with no visible light source — Dimplex's case in one product, and the thing Napoleon has no answer to.
If the reason you are comparing these two brands is that ordinary electric flames do not convince you, the comparison is already over and this is the product. Revillusion is a genuinely deep firebox — 12 1/8 inches — with a mirror-free viewing area and a herringbone brick interior, and depth is what separates a convincing fire from a lit panel. The effect survives being looked at from below and from the side, which is where almost everything else in the category gives itself away.
It is also the better-documented of the two brands' built-ins, which is not what the prices would lead you to expect. The Revillusion manual publishes a full rough-in framing table — for the RBF30 a framed opening 30 5/8 inches wide by 26 3/16 high at a framing depth of 12 1/2 inches — and states that the firebox needs no special venting and is a zero-clearance design except at the top, where insulation and vapor barrier must stay 2 inches clear. Napoleon publishes no rough opening at all for its flagship.
The heat is real rather than nominal: Dimplex rates it up to 8,794 BTU per hour, but only on the higher-voltage configuration, which is a hardwired job for a licensed electrician rather than something you plug in.
The honest costs. At 12 1/8 inches deep it will not go into a 2x4 or even a 2x6 wall — it needs a purpose-built enclosure, which is a cabinetmaker's project and the reason we wrote electric fireplaces in a cabinet or media wall. It is a firebox, not a plug-in panel. And on a standard 120 V circuit it is bound by the same ceiling as everything else.
What it does not do: This is a firebox, not a plug-in wall unit. At 12 1/8 in deep it will not go into a 2x4 or even a 2x6 wall — it needs a purpose-built enclosure. The higher BTU figures require a higher-voltage hardwired supply and a licensed electrician.

#2 · When the opening is the problem
Napoleon CLEARion Elite 50 See-Thru (NEFBD50HE)
The only true see-through unit in general circulation, and the only fireplace on this site that exceeds 1,500 watts.
This is Napoleon's case, and it is the clearest example on the site of a brand selling something that has no competitor. The CLEARion is built into a wall between two rooms with glass on both faces, with a viewing area of 43.625 by 12 inches. When we last searched the current catalog the only true see-through electric fireplaces on sale were this and its 60-inch sibling.
It is also the single exception to the rule the rest of this site is built on. Wired to 240 volts at 15 amps it is rated at 3,000 watts and up to 10,000 BTU per hour, because the two heaters operate independently — one per room. Every other unit we list, Dimplex included, is capped at about 5,118 BTU by a 120 V circuit.
The privacy glass is the feature that makes the format livable rather than merely impressive: it switches between transparent and opaque, which is what lets a window between two rooms exist at bedtime.
And the costs, which are substantial. The 3,000 W and 10,000 BTU figures are the 240 V ratings on a 15 A circuit most living rooms do not have; on ordinary 120 V power you are back in the normal category. Napoleon publishes no rough opening for this size, no coverage figure, and no separate 120 V wattage — and the retailer and Amazon dimensions disagree by about half an inch in height and an inch in depth, so measure against the manufacturer's drawing before framing anything. The full job is costed on see-through electric fireplaces.
What it does not do: The same 240 V caveat as the 60: the 3,000 W and 10,000 BTU figures are the 240 V ratings, and the retailer specification lists 15 A, which is a circuit most living rooms do not have. Napoleon publishes no rough opening for this size, no coverage figure in square feet, and no separate 120 V wattage — we quote the 60-inch model's 120 V figure nowhere on this unit because Napoleon does not state it for the 50. Retailer and Amazon dimensions disagree by about half an inch in height and an inch in depth, so measure against the manufacturer's drawing before framing.

#3 · Napoleon's other monopoly, at a normal price
Napoleon Allure Vertical 38 (NEFVC38H)
Thirty-eight inches tall and sixteen wide — a shape Dimplex does not make, on a wall a linear unit cannot use.
The see-through is the headline, but this is the Napoleon format more people actually need. A chimney breast, a pier between two windows, the narrow end of a galley room — these are tall, narrow surfaces, and a 50-inch horizontal slot is simply the wrong shape for them. Dimplex's range is linear and firebox; it has nothing for this wall.
The engineering is better than the format usually gets. Napoleon publishes 38 inches high by 16 wide by 5 1/2 deep, 1,500 W, 5,000 BTU per hour and a rating up to 400 square feet, with a hidden vent and angled glass that pushes heat out into the room rather than straight up the wall above it — which is the failure mode of a tall heater at head height. Four flame colors, five speeds and four ember-bed brightness settings, and it runs with or without heat.
It hangs and plugs into a standard 120 V outlet, which makes it the only pick on this page that is not a construction project.
Against that: it is six inches taller than the Allure Vertical 32 and meaningfully more expensive for the same 1,500 W heater, so you are buying height rather than warmth. It has been showing as low-quantity on Amazon, so confirm stock before committing a wall to it. And the whole range is decoded on Napoleon electric fireplaces.
What it does not do: Six inches taller than the 32 and meaningfully more expensive for the same 1,500 W heater — you are buying height, not warmth. Like its smaller sibling it has been showing as low-quantity on Amazon, so confirm stock before committing to a wall.

Dimplex Prism 50" Linear Fireplace (BLF5051)
The one place Dimplex competes head-on with Napoleon on a linear panel, and the place it loses on the numbers.
Everywhere else on this page the two brands are selling different things. Here they are selling the same thing — a wall-mounted linear panel around fifty inches — and this is the honest result of that collision.
Dimplex publishes 120 V, 1,230 W and 4,197 BTU per hour for the Prism 50. That is roughly 18% below the 1,500 W class ceiling, which means genuinely less heat than most units at this width, including units costing a fraction of it. At 7 inches deep it is also the thickest linear unit in our catalog, so it needs more wall than a slimmer panel for less output.
It is the older Prism series rather than the current IgniteXL, and Dimplex's own ladder tells the story: the step up from here is the IgniteXL, which costs substantially more again. Napoleon's Entice sits between the two on price and does not give up the wattage.
None of that makes it a bad fireplace — the acrylic ice ember bed is distinctive, it mounts fully recessed, partially recessed or on the surface, and it carries a two-year warranty. But if you are choosing between these brands for a fifty-inch linear panel, this is not the reason to choose Dimplex. Choose Dimplex for the flame technologies, which is what it is actually unmatched at.
What it does not do: 1,230 W and 4,197 BTU/hr put it roughly 18% below the 1,500 W class ceiling — genuinely less heat than most units at this width. At 7 in deep it is also the thickest linear unit in our catalog, and it is the older Prism series rather than the current IgniteXL.

Questions people actually ask
Is Dimplex or Napoleon the better electric fireplace brand?
Neither, in the abstract — they are strong at different things. Dimplex owns the flame technologies: Opti-Myst water vapor and the Revillusion concealed-source firebox are not matched by anyone, Napoleon included. Napoleon owns the formats: the CLEARion is the only true see-through electric fireplace in general circulation, and the Allure Vertical fits walls no linear unit can use. Decide which of those two problems you have and the brand follows.
Does Napoleon make more heat than Dimplex?
Only in one model, and only on a circuit most homes do not have. The Napoleon CLEARion is rated at 3,000 watts and up to 10,000 BTU per hour wired to 240 volts at 15 amps, because it carries two heaters working independently into two rooms. Every other unit from either brand is capped at about 5,118 BTU per hour by a standard 120 V circuit, which is the ceiling for the entire category.
Which brand is easier to build into a wall?
Dimplex, and the prices do not predict it. The Revillusion owner's manual publishes a rough-in framing table, states that the firebox needs no special venting, and gives a clearance rule for insulation at the top. Napoleon publishes no rough opening for the CLEARion 50 and no coverage figure, and its retailer and Amazon dimensions do not agree. We go through what a joinery project actually needs on electric fireplaces in a cabinet or media wall.
Is a Dimplex Prism worth it against a Napoleon linear?
On the numbers, no. Dimplex publishes 1,230 watts and 4,197 BTU per hour for the Prism 50, about 18% below the 1,500 W class ceiling, and at 7 inches it is the deepest linear unit we list. Napoleon's Entice sits between the Prism and the Dimplex IgniteXL on price without giving up the wattage. Buy Dimplex for Opti-Myst or Revillusion, which is what the brand is genuinely unmatched at.
Do either of these brands sell a flame that produces no heat?
Both can run flame-only, and that is normal across the category — the heater is a separate switch. Dimplex goes further with Opti-Myst, where the mist flame produces no meaningful heat at all by design and a direct-wire heater is a separate accessory. Our guide to electric fireplaces without heat covers when that is the product you actually want.
