What it's made for: a bedroom, a study or a narrow wall.
The two built-in electric fireplaces closest to it on our rating, with a dated price.
The heat the listing states, next to 8,786 BTU. Plenty to take the chill off the room you sit in; how far it reaches depends on your insulation, windows and ceiling, and our supplemental heat planner turns your room into a rough answer.
What it has going for it
42 in wide, per the listing. A compact size for a narrow wall, a bedroom or a study. Check in the installation drawing whether the figure is the frame or the viewing area, then hold it against your wall cavity.
2,575 W / 8,786 BTU. Supplemental heat for the room you sit in: it takes the edge off a cold evening while the furnace stays turned down. Real coverage depends on your insulation, windows and ceiling height. Our supplemental heat planner puts it in numbers for your room.
Plugs into a standard outlet. No electrician for the basic setup: plug it into an ordinary household outlet, on its own, without an extension cord or a power strip. Our power requirements guide explains why that matters.
The seller states, word for word, in the Dimplex Revillusion RBF42WC Concrete listing:
Simply surface mount and plug-in or fully recess and direct wire for quick installation.
This 42-inch Revillusion fireplace has 1375/1975/2575 Watt capabilities for a powerful performance.
Enjoy lasting service with a 2-year parts, 1-year service limited warranty.
Hold these against the manual of the exact model before you order.
What the Dimplex Revillusion RBF42WC Concrete listing names:
Check the opening, the depth and the outlet against your wall before you order.
At the price on Sep 30, 2026, each stated inch of width costs about $52. That puts it in the pricier third of the 117 inserts we have a price for.
Cost per inch is only a rough yardstick: the heater, the flame options and the build count as much as the width.

Want a wider fire for a bigger wall? The Touchstone Sideline 60" Smart (9.5/10) states 60 in.
Want the flame without the heat in summer? The Dimplex Prism 50" Wall-Mount (7.6/10) states a flame-only mode.
More flame colors? The Xbeauty 50" Recessed and Wall Mounted (9.2/10) lists 12.
Our take
We like the Dimplex Revillusion RBF42WC Concrete for a 42-inch width and a 2,575 W heater. No buyer reviews yet, so the Dimplex Revillusion RBF42WC Concrete has to win you over on paper. The catch with the Dimplex Revillusion RBF42WC Concrete: no flame-only mode in the listing, while most picks here state one. We'd pick it if you have a narrow wall or a bedroom to warm up; otherwise, put it next to the Sixfivsevn 36" Recessed and Wall Mounted first.
A big, flat box with glass inside: open it with two people and check the front before the cardboard goes out.
Try the flame at a few brightness settings; lower often looks more real at night. The 2,575 W / 8,786 BTU heater takes the chill off the room you sit in.
A quick dust of the glass now and then, and a look at the manual's cleaning page once a season. Our maintenance guide has the rest.
Check whether the flame can run without the heater; the listing we read doesn't say so.
Before you add the Dimplex Revillusion RBF42WC Concrete to your cart: check your wall, because the 42-inch figure has to match your opening, and a listing width can mean the frame or just the viewing area.
Draw the opening on the wall with painter's tape at the real size, step back, and check it against the installation drawing. Our recessed installation guide lists the clearances to ask about.
Pick the outlet before you pick the finish: a free one close by, nothing heavy on the same circuit, and no extension cord. Our power requirements guide lists the questions to ask.
2,575 W / 8,786 BTU stated. Treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer.
Glass-fronted inserts are big, flat boxes: plan two people for the unboxing, and decide early who frames the wall. Our built-in vs wall-mounted guide weighs recessed against wall-mounted.
How the Dimplex Revillusion RBF42WC Concrete stacks up against the closest alternative, the Sixfivsevn 36" Recessed and Wall Mounted.
| Criterion | Dimplex Revillusion RBF42WC Concrete | Sixfivsevn 36" Recessed and Wall Mounted |
|---|---|---|
| Our rating | 6.8/10 | 6.8/10 |
| Width | 42 in | 36 in |
| Heater | 2,575 W / 8,786 BTU | 1,500 W |
| Coverage claim | Not stated | 400 sq ft |
| Flame colors | Not stated | 12 |
Both score 6.8/10. The Sixfivsevn 36" Recessed and Wall Mounted adds a bigger coverage claim (400 sq ft) and more flame colors (12), while the Dimplex Revillusion RBF42WC Concrete brings a wider unit (42 in) and more stated heat (2,575 W / 8,786 BTU).
We rate it 6.8/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.
Its listing states a 42-inch width and recessed (in-wall) installation. Those are the maker's figures, so check in the installation drawing whether the width means the frame, the firebox or the opening. The listing we read gives no heater figure, so ask the seller before you count on it for warmth.
The listing we read does not state its supply voltage or heater wattage. Read the supply, plug and circuit conditions on the exact listing and in the manual before you order, and never run a heater on an extension cord or a shared power strip. Anything beyond an existing standard outlet, hardwiring or 240 V included, is a job for a licensed electrician.
Its listing states a 42-inch width, a 2,575 W heater and a plug-in setup. Those are the seller's figures; for how real the flames look in a living room and how loud the fan runs at night, the buyer reviews are the better guide.
