7.3Good · out of 10Rated from the listing's specs, no buyer reviews yet

The Masarflame 36" Retro Insert ticks most of the boxes we care about: 36 inches of fire across the wall, 1,500 watts of supplemental heat and a flame that runs without the heat. With a timer as well, it suits a cosy corner that never had a chimney.

Heater output, per the listing

The heat the listing states, next to 5,000 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

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 / 5,000 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.

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 400 sq ft coverage claim is pitched at a main room, not a box room.

For a bedroom or a study, at 36 in wide it fits a bedroom wall or a study. The timer switches it off after you fall asleep. 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

$339.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated inch of width costs about $9.44. 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 B07ZVRBRGR), where today's price, stock and seller apply.

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

Our take

The verdict

Our favourite thing about the Masarflame 36" Retro Insert is 36 inches of fire across the wall, closely followed by 1,500 watts of supplemental heat. No buyer reviews yet, so the Masarflame 36" Retro Insert has to win you over on paper. The catch with this Masarflame built-in electric fireplace: watts and square-footage claims are the seller's, so your room, windows and insulation decide what you really feel. We'd pick the Masarflame if you have a narrow wall or a bedroom to warm up; 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 1,500 W / 5,000 BTU heater takes the chill off the room you sit in.

Day to day

The remote on the sofa arm, 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 add the Masarflame 36" Retro Insert to your cart: 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

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

1,500 W / 5,000 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 Masarflame 36" Retro Insert 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 Masarflame 36" Retro Insert state?

Its listing states a 36-inch width, a 1,500 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 1,500 W in context for your room.

What power supply does the Masarflame 36" Retro Insert need?

The listing states 120 V and a 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 Masarflame 36" Retro Insert?

Its listing states a 36-inch width, a 1,500 W heater, a flame that runs without the heat and a 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 Masarflame 36" Retro 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: 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: 1,500 W / 5,000 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.
