Heater output, per the listing

The heat the listing states, next to a 450 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

21 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, up to 450 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 450 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 450 sq ft coverage claim is pitched at a main room, not a box room.

For a bedroom or a study, at 21 in wide it fits a bedroom wall or a study. 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 want the glow all year, heat or no heat

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

$109.98 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated inch of width costs about $5.24. 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

We like the Electactic 21" Insert Log Heater Set for a 21-inch width and a 1,500 W heater. No buyer reviews yet, so this Electactic electric fireplace insert has to win you over on paper. The catch with the Electactic: no word on the supply it needs. We'd pick the Electactic 21" Insert Log Heater Set 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

Try the flame at a few brightness settings; lower often looks more real at night. The 1,500 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

Before you add the Electactic 21" Insert Log Heater Set to your cart: check your wall, because the 21-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 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 Electactic 21" Insert Log Heater Set stacks up against the closest alternative, the BETELNUT 50" Wall/Recessed.

Criterion	Electactic 21" Insert Log Heater Set	BETELNUT 50" Wall/Recessed
Our rating	7.1/10	7.2/10
Width	21 in	50 in
Coverage claim	450 sq ft	400 sq ft
Flame without heat	Stated	Not stated

Pick the BETELNUT 50" Wall/Recessed if you want our higher-rated option (7.2/10), with a wider unit (50 in); stay with the Electactic 21" Insert Log Heater Set for a bigger coverage claim (450 sq ft) and a flame-only mode.

Frequently asked questions

Is the Electactic 21" Insert Log Heater Set any good?

We rate it 7.1/10 (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 21" Insert Log Heater Set state?

Its listing states a 21-inch width, a 1,500 W heater output and freestanding installation. Those are the maker's figures, so tape the width on the floor and check it against your wall and your TV before you order. Our supplemental heat planner puts 1,500 W in context for your room.

What power supply does the Electactic 21" Insert Log Heater Set 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 21" Insert Log Heater Set?

Its listing states a 21-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 Electactic 21" Insert Log Heater Set?

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 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.
