Heater output, per the listing

The heat the listing states, next to 5,118 BTU and 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

100 in wide, per the listing. A long, linear fire that can carry a whole feature wall. Check in the installation drawing whether the figure is the frame or the viewing area, then hold it against your wall cavity.

1,500 W / 5,118 BTU, 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, 100 inches of fire are wide enough to anchor a big wall. 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 is a living-room centrepiece that can also do a smaller room, not the other way round.

Great for you if…

  • You are building a feature wall around a big TV
  • You want the chill off one room on cold evenings
  • You want the glow all year, heat or no heat

Skip it if…

  • Your wall can't give it 100 in plus the clearances in the manual
  • You want to plug in, not call an electrician
  • 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

Price and cost per inch of width

$3,765 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated inch of width costs about $38. 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.

The button opens the exact listing (ASIN B01LXXPIPU), 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?

Short on wall space? The Touchstone Sideline 60" Smart (9.5/10) is 60 in wide, per its listing.

Our take

The verdict

We like the Dimplex IgniteXL 100" (XLF100) for a 100-inch width and a 1,500 W heater. No buyer reviews yet, so the Dimplex IgniteXL 100" (XLF100) has to win you over on paper. The catch with the Dimplex IgniteXL 100" (XLF100): no word on the supply it needs. We'd pick the Dimplex IgniteXL 100" (XLF100) if you are building a feature wall around a big TV; otherwise, put it next to the Sixfivsevn 36" Recessed and Wall Mounted 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 1,500 W / 5,118 BTU 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

Before you add the Dimplex IgniteXL 100" (XLF100) to your cart: check the wiring, because the listing mentions hardwiring, and that means booking a licensed electrician before the install day.

Before you buy

Your wall

100 in wide, per the listing. Measure the cavity or the opening (width, height and the depth the manual asks for) and hold it against the installation drawing of this exact model. Our recessed installation guide has the order.

The outlet

Ask an electrician for a quote before you order, and check whether the unit can also plug in. Our power requirements guide explains the difference.

Heat for your room

1,500 W / 5,118 BTU 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.

Frequently asked questions

Is the Dimplex IgniteXL 100" (XLF100) any good?

We rate it 6.8/10 (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 IgniteXL 100" (XLF100) state?

Its listing states a 100-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.

What power supply does the Dimplex IgniteXL 100" (XLF100) need?

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.

What do you get with the Dimplex IgniteXL 100" (XLF100)?

Its listing states a 100-inch width, a 1,500 W heater and a flame that runs without the heat. 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 IgniteXL 100" (XLF100)?

Your wall: 100 in wide, per the listing. Measure the cavity or the opening (width, height and the depth the manual asks for) and hold it against the installation drawing of this exact model. Our recessed installation guide has the order. The outlet: ask an electrician for a quote before you order, and check whether the unit can also plug in. Our power requirements guide explains the difference. Heat for your room: 1,500 W / 5,118 BTU stated. Treat it as supplemental heat for one room.
