Heater output, per the listing

The heat the listing states, next to 5,100 BTU and a 400 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

50 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.

1,500 W / 5,100 BTU, up to 400 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 400 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.

12 flame colors, 12 ember-bed colors. Classic orange for winter evenings, something bolder when friends are over, or just the embers glowing behind a movie. How real each setting looks is for your eyes to judge in the photos and videos; the count is the seller's. Our flame effects guide sorts the settings you'll use from the ones you'll forget.

Living room or bedroom?

For the living room, 50 inches of fire are wide enough to anchor a big wall. A 400 sq ft coverage claim is pitched at a main room, not a box room. All those flame colors are made for showing off when friends come round.

For a bedroom or a study, the timer (up to 8 hours) switches it off after you fall asleep. The thermostat holds the temperature instead of baking the room. The low heat setting is gentle enough for a smaller room.

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 want the chill off one room on cold evenings
You like to change the mood of the room
You hate fiddling with the heat

Skip it if…

You want the flame on its own in summer: the listing we read doesn't say the flame runs without heat
Your wall can't give it 50 in plus the clearances in the manual
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

What Electactic promises

750W energy-saving or 1500W high-efficiency, warming spaces up to 400 sq. ft.

Price and cost per inch of width

$159.98 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated inch of width costs about $3.20. That puts it in the cheaper 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.

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

The Electactic 50" Ultra-Thin Insert earns its place with a 50-inch width and a 1,500 W heater. No buyer reviews yet, so this Electactic recessed or wall-mounted fireplace has to win you over on paper. The catch with the Electactic: no flame-only mode in the listing, while most picks here state one. We'd pick it if you want the chill off one room on cold evenings; otherwise, put it next to the Dimplex IgniteXL 100" Driftwood Kit 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

Run through the flame colors once, then settle on the one that suits the room. The 1,500 W / 5,100 BTU heater takes the chill off the room you sit in.

Day to day

The remote on the sofa arm, the thermostat set once, the timer for bedtime, and a quick dust of the glass now and then. Our maintenance guide has the rest.

Summer

Check whether the flame can run without the heater; the listing we read doesn't say so.

The one thing we'd check first

One thing to settle before the Electactic 50" Ultra-Thin Insert ships: check your wall, because the 50-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

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

1,500 W / 5,100 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 Electactic 50" Ultra-Thin Insert any good?

We rate it 7.0/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

What size and heater output does the Electactic 50" Ultra-Thin Insert state?

Its listing states a 50-inch width, a 1,500 W heater output 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 1,500 W in context for your room.

What power supply does the Electactic 50" Ultra-Thin Insert need?

The listing states 1,500 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 Electactic 50" Ultra-Thin Insert?

Its listing states a 50-inch width, a 1,500 W heater, 12 flame colors, a thermostat and a 8-hour timer. 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 Electactic 50" Ultra-Thin Insert?

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: 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: 1,500 W / 5,100 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.
