What it's made for: a cosy corner that never had a chimney.
The two built-in electric fireplaces closest to it on our rating, with a dated price.
What it has going for it
35 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.
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.
For a bedroom or a study, at 35 in wide it fits a bedroom wall or a study. 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.
The seller states, word for word, in the SimpliFire SF-INS35 35" Built-in listing:
Textured log set creates impressive firebox appeal.
Four flame intensity levels offer a customized fire.
Includes integrated heater for added ambiance and warmth; Unit can be operated with or without heat.
Hold these against the manual of the exact model before you order.
What the SimpliFire SF-INS35 35" Built-in listing names:
Check the opening, the depth and the outlet against your wall before you order.
At the price on Sep 30, 2026, each stated inch of width costs about $39. 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.

Want a wider fire for a bigger wall? The Touchstone Sideline 60" Smart (9.5/10) states 60 in.
Our take
The SimpliFire SF-INS35 35" Built-in earns its place with 35 inches of fire across the wall and a flame that runs without the heat. No buyer reviews yet, so this SimpliFire built-in electric fireplace has to win you over on paper. The catch with the SimpliFire: no heater output in the listing, while most picks here state one. We'd pick it if you have a narrow wall or a bedroom to warm up; otherwise, put it next to the Amantii Panorama Xtraslim Lumina first.
A big, flat box with glass inside: open it with two people and check the front before the cardboard goes out.
Try the flame at a few brightness settings; lower often looks more real at night.
A quick dust of the glass now and then, and a look at the manual's cleaning page once a season. Our maintenance guide has the rest.
Heater off, flame on: the glow stays on the wall in July without warming the room.
One thing to settle before the SimpliFire SF-INS35 35" Built-in ships: check your wall, because the 35-inch figure has to match your opening, and a listing width can mean the frame or just the viewing area.
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.
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.
Treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer.
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 the SimpliFire SF-INS35 35" Built-in stacks up against the closest alternative, the Amantii Panorama Xtraslim Lumina.
| Criterion | SimpliFire SF-INS35 35" Built-in | Amantii Panorama Xtraslim Lumina |
|---|---|---|
| Our rating | 6.0/10 | 6.0/10 |
| Width | 35 in | Not stated |
| App / Alexa | Not stated | Stated |
| Flame without heat | Stated | Not stated |
Both score 6.0/10. The Amantii Panorama Xtraslim Lumina adds app or voice control, while the SimpliFire SF-INS35 35" Built-in brings a wider unit (35 in) and a flame-only mode.
We rate it 6.0/10 (fair). The rating comes from its documented listing alone, as no customer-review record is captured yet.
Its listing states a 35-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.
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.
Its listing states a 35-inch width 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.
