Heater output, per the listing

The heat the listing states, next to 2,559 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

What changes in your evenings

36 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.

1,500 W / 2,559 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.

3 flame 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 a bedroom or a study, at 36 in wide it fits a bedroom wall 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. The flame runs without heat, so it can glow on a warm night too.

On balance it is happiest in a bedroom, a study or a cosy corner.

Great for you if…

You have a narrow wall or a bedroom to warm up
You want the chill off one room on cold evenings
You like to change the mood of the room

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

$219.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated inch of width costs about $6.11. 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.

Our take

The verdict

Our favourite thing about the Giantex 36" Electric Fireplace Insert is 36 inches of fire across the wall, closely followed by 1,500 watts of supplemental heat. No buyer reviews yet, so the Giantex 36" Electric Fireplace Insert has to win you over on paper. Our main reservation: no word on the supply it needs. We'd pick it if you have a narrow wall or a bedroom to warm up; otherwise, put it next to the BETELNUT 50" Wall/Recessed 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 / 2,559 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

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 order the Giantex 36" Electric Fireplace Insert: check your wall, because the 36-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 / 2,559 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 Giantex 36" Electric Fireplace Insert any good?

We rate it 7.2/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

What size and heater output does the Giantex 36" Electric Fireplace Insert state?

Its listing states a 36-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 Giantex 36" Electric Fireplace 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 Giantex 36" Electric Fireplace Insert?

Its listing states a 36-inch width, a 1,500 W heater, 3 flame colors, a flame that runs without the heat, 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 Giantex 36" Electric Fireplace 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 / 2,559 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.
