Heater output, per the listing

The heat the listing states, next to a 1,000 sq ft coverage claim. 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

What changes in your evenings

48 in wide, per the listing. Wide enough to be the focal point of a living-room wall. Check in the installation drawing whether the figure is the frame or the viewing area, then hold it against your wall cavity.

1,400 W, up to 1,000 sq ft claimed. Supplemental heat for the room you sit in: it takes the edge off a cold evening while the furnace stays turned down. The 1,000 sq ft figure is the seller's; real coverage depends on your insulation, windows and ceiling. Our supplemental heat planner puts it in numbers for your room.

Flame without heat. The heater and the flame run separately, so you can have the glow in July without warming the room. The fireplace earns its place all year, not only in January.

Living room or bedroom?

For the living room, a 1,000 sq ft coverage claim is pitched at a main room, not a box room.

For a bedroom or a study, the flame runs without heat, so it can glow on a warm night too.

On balance it covers both, as long as your wall and your outlet match its numbers.

Great for you if…

You want the chill off one room on cold evenings
You want the glow all year, heat or no heat
You like to switch between a rustic and a modern look

Skip it if…

You want it to replace your heating: it is supplemental heat for one room
You'd rather wait for buyer reviews: none are captured for this listing yet
You want to run it from your phone: the listing names no app or WiFi

Price and cost per inch of width

$479.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated inch of width costs about $10.00. That puts it around the middle 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.

The button opens the exact listing (ASIN B07SPFBF1G), where today's price, stock and seller apply. Sizes and bundles of the same family often sit at different prices.

A better fit for your room?

Want a wider fire for a bigger wall? The Touchstone Sideline 60" Smart (9.5/10) states 60 in.

Short on wall space? The Innoflame 36" Insert with Log Set (7.7/10) is 36 in wide, per its listing.

Want to run it from your phone? The LegendFlame 60" Smart Wall/Recessed (8.8/10) works with Alexa, per its listing.

Our take

The verdict

Our favourite thing about the Dimplex Sierra 48" Wall-Mount is 48 inches of fire across the wall, closely followed by 1,400 watts of supplemental heat. No buyer reviews yet, so the Dimplex Sierra 48" Wall-Mount has to win you over on paper. Where it falls short: watts and square-footage claims are the seller's, so your room, windows and insulation decide what you really feel. We'd pick it if you want the chill off one room on cold evenings; otherwise, put it next to the Burutpike 50" Ultra-Thin Recessed/Wall first.

Living with it

Delivery day

A big, flat box with glass inside: open it with two people and check the front before the cardboard goes out.

The first evening

Try the flame at a few brightness settings; lower often looks more real at night. The 1,400 W heater takes the chill off the room you sit in.

Day to day

The remote on the sofa arm, and a quick dust of the glass now and then. Our maintenance guide has the rest.

Summer

Heater off, flame on: the glow stays on the wall in July without warming the room.

The one thing we'd check first

One thing to settle before the Dimplex Sierra 48" Wall-Mount ships: check your wall, because the 48-inch figure has to match your opening, and a listing width can mean the frame or just the viewing area.

Before you buy

Your wall

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.

The outlet

120 V, per the listing. 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.

Heat for your room

1,400 W stated. Treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer.

Delivery and install

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 it compares

How the Dimplex Sierra 48" Wall-Mount stacks up against the closest alternative, the Burutpike 50" Ultra-Thin Recessed/Wall.

Criterion	Dimplex Sierra 48" Wall-Mount	Burutpike 50" Ultra-Thin Recessed/Wall
Our rating	7.3/10	7.3/10
Width	48 in	50 in
Heater	1,400 W	1,500 W
Coverage claim	1,000 sq ft	400 sq ft
Flame colors	Not stated	4

Both score 7.3/10. The Burutpike 50" Ultra-Thin Recessed/Wall adds a wider unit (50 in) and more stated heat (1,500 W), while the Dimplex Sierra 48" Wall-Mount brings a bigger coverage claim (1,000 sq ft).

Frequently asked questions

Is the Dimplex Sierra 48" Wall-Mount any good?

We rate it 7.3/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

What size and heater output does the Dimplex Sierra 48" Wall-Mount state?

Its listing states a 48-inch width, a 1,400 W heater output, a 120 V supply 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. Our supplemental heat planner puts 1,400 W in context for your room.

What power supply does the Dimplex Sierra 48" Wall-Mount need?

The listing states 120 V and a 1,400 W heater. 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.

What do you get with the Dimplex Sierra 48" Wall-Mount?

Its listing states a 48-inch width, a 1,400 W heater, a flame that runs without the heat, logs and crystals to switch between 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.

What should I check before ordering the Dimplex Sierra 48" Wall-Mount?

Your wall: 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. The outlet: 120 V, per the listing. 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. Heat for your room: 1,400 W stated. Treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer. Delivery and install: 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.

Where can I buy the Dimplex Sierra 48" Wall-Mount?
