Real Living Rooms. Real Cold Winter Nights. Real Log-Flame Insert.
You have an existing mantel surround, a TV console cutout, or a sealed-off fireplace opening. You do not want to gut it, hire a contractor, and pay $2,000 for a real insert. That is what this is for.
4 Things We Care About
Built to Last, Not to Impress
Built for the Existing Fireplace, the TV Stand, and the Long Winter Evening.
Iron and steel housing. Tempered glass front. 1400W, 5,000 BTU, self-regulating. Front-strip vent design pushes warm air out the top so the glass stays cool to touch and nothing hot faces the room. Weighs 13.5 lbs - one person can carry it in from the porch and lift it into an opening without help.
Slide it in tonight. Warm the room while amber log flames dance behind tempered glass. The mantel you sealed off years ago is finally doing something again.
Drop It In. Plug It In. Warm the Room. Watch the Log Flame. Tonight.
Measure your existing opening against 18"W x 17.5"H x 5"D. If it fits, slide it in - the mounting flanges on the corners will screw into wood if you want it locked, otherwise gravity holds it. Plug into a standard wall outlet on its own circuit. Point the remote. Watch the amber logs light up.
No wall bracket to anchor into studs. No drywall to cut. No contractor. No inspection.
Real homeowners. Real insert.
"Our 1960s brick fireplace surround has been decorative-only since we capped the flue during a chimney inspection back in 2003. Twenty years of an empty rectangular hole in the living room wall. My grandson helped me carry The Firebox in from the porch, we slid it into the opening, plugged it in, and I actually cried a little when the flames came on. The room feels warm again, in a way it hasn't since my husband passed. It matters more than I expected."
"Retired mechanical engineer, 40 years in aerospace. I read the spec sheet - 18"W x 17.5"H x 5"D - measured my existing masonry cutout at 20 x 19 x 8, saw it would fit with a half inch of margin on each side, and ordered it. Kill-A-Watt reads exactly 1400W on high. It has a remote and touch buttons on the top. That's it. No app, no WiFi, no Alexa sync, no cloud account to create. In 2026 that's not an oversight, that's the point."
"Small mountain cabin in the Berkshires. The original wood stove hearth is a flat piece of bluestone about 3 feet wide. I set The Firebox right on top - no bracket, nothing holding it down but its own weight. The log-flame effect at dusk with the log walls behind it - guests genuinely ask if it's a real fire before they touch the glass. My old wood stove needed hauling logs from the porch in a foot of snow. This one takes a wall outlet. That's the trade I wanted."

Slid straight into our existing 1980s brick surround. Room finally feels used.
We have had a decorative fireplace since we bought the house in 1987 - our previous owner had already sealed the flue. Twenty-seven years of an empty brown-brick hole. I measured the opening at 20 x 19, ordered The Firebox at 18 x 17.5, and my son helped me slide it in on a Sunday afternoon. Plug went into the wall outlet that used to run a gas insert we removed a decade ago. Flames on. My husband did not even look up from his crossword before saying "leave that on for the winter." It has been on every evening for six weeks. The log flame effect is more convincing than I expected in the 5:30 PM dim light. Not real fire, obviously - but real enough that our house feels warm in a way it hasn't.

Retired. Wanted controls I understood. Remote and touch buttons only. Perfect.
Every space heater I looked at came with an app requirement. I do not want an app. I am 68. I want a button, a remote, and a knob if possible. The Firebox has the remote, has touch buttons on the top strip, no app, no WiFi setup, no Alexa. My wife and I set the thermostat to 72 with the remote from the couch and the flame comes on. When we go to bed we press the power button on the top. That is the entire user manual. It is a machine that behaves like a machine, which is what a retired mechanical engineer prefers.

Retrofit into a TV console cutout that came from the factory with a fireplace-shaped hole. Perfect fit.
Bought a large media console from a big-box store six years ago. It came with a rectangular fireplace-insert-shaped cutout in the middle, sold with an optional insert that we never bought. That empty rectangle has annoyed my wife for six years. Measured it at 23 x 18 - The Firebox at 18 x 17.5 slid right in with about 2 inches of margin on each side. Held in by gravity and the flat back of the console. Plugged into the surge protector behind the console. Wife stopped complaining, which is the review.

Contractor quoted $2,800 to convert my sealed-off fireplace to a gas insert. This was $250.
The masonry fireplace in our 1970s ranch has been sealed since we bought the house - the chimney needed a full rebuild that we were not going to pay for. Contractor came out to quote a gas insert conversion: $2,800 for the insert, $1,600 for the gas line, plus permit inspection. About $4,800 total. I ordered The Firebox for $250 and it slid straight into the existing opening. Plug in a nearby outlet. Done. Yes it's an electric log flame, not real gas. But at 5% of the cost and no permit, I can live with the tradeoff.

HVAC tech. 1400W tested with the meter, warms my 300 sq ft office as advertised.
HVAC / electrical tech, 22 years in the trade. Put a clamp meter on the plug: reads exactly 12A at 120V under load = 1440W. Label says 1400W. Close enough that I have zero complaints. Coverage rating is 400 sq ft - I put mine in my 300 sq ft home office and it goes from 62 to 72 in about 20 minutes and holds it. Would not try to heat a 600 sq ft open-plan room with this. Sized right for the small-to-medium room, which the label honestly says.

Guest bedroom retrofit into an old brick fireplace surround. Guests love it.
Small guest bedroom in our old farmhouse has an original small brick fireplace opening - long since sealed. Fit The Firebox into the opening and set the flame on low, thermostat 68. First guests to use the room this winter were my in-laws over Thanksgiving. They came out of the room the first morning saying "your guest room is the coziest room in the house now." That is quite a compliment given my mother-in-law's standards.

Sign In to ContinueDifferent product family entirely. The Crystal Panel line is designed to hang flat on a wall like a mounted TV - great for a modern living room where you don't have an existing fireplace. The Firebox is designed to drop into something that already exists: an old masonry fireplace opening, a TV console cutout, a cabinet opening, or a flat hearth stone. If you have a rectangular hole in your wall or your furniture that has been sitting empty, this fills it. If you have a bare flat wall and want something modern hung on it, look at the Crystal Panel instead.
No. It is an LED-lit visual effect behind a tempered glass front, with a molded resin log bed that lights up. The flames are convincing at normal viewing distance, especially in evening light, but there is no combustion, no real fire, no wood being burned. That's the tradeoff: you get a warm glow with no smoke, no ash, no chimney inspection, no wood to haul.
Any opening at least 19" wide, 17.5" tall, and 5" deep with a wall outlet within cord reach. Common installs: an existing sealed-off masonry fireplace, a TV console with a fireplace-shaped cutout, a cabinet or built-in with a rectangular opening, or freestanding on a flat hearth stone / raised platform. There is no wall-mount bracket - this product is not designed to hang on a bare wall. If that's what you need, look at the Crystal Panel line instead. Do NOT install into a working chimney flue where a real fire has ever burned - the flue soot could damage the electronics.
Wipe the tempered glass front with a soft dry cloth every few weeks to keep dust off the flame view. Occasionally vacuum the front-strip vent with a brush attachment to keep dust from building up on the heating element. Do not use liquid cleaners or sprays anywhere near the vent or the top control panel. Do not open the housing - there are no user-serviceable parts inside.
The flame-only mode (no heat) draws roughly 12-14W - about the same as a nightlight - and is designed for that. The heat mode should not be left running unattended, ever - that's true of any space heater. Use the 0-6 hour timer if you want the heat to run for a set period and then shut itself off. Never leave heat mode on when you leave the house or go to sleep.
At 18 x 17.5 x 5 inches and 13.5 lbs it will physically fit in a large RV or fifth-wheel with a built-in fireplace cutout. Draw is 1400W (about 12A at 120V), which means it needs its own dedicated circuit and will not run off a small inverter or off-grid solar setup unless you have significant generator capacity. If your generator is 3000W+ continuous, it will run fine. Small 1000W-1500W inverters cannot handle it.

Another cold night is coming. You already know what it feels like.
Every 1500W-class heater on the market makes the same heat. What differs about this one: 18 inches of realistic amber log flame behind tempered glass, dropping straight into the existing fireplace opening, TV console cutout, or cabinet opening you already have. No contractor. No permit. No app to configure. Plug it in tonight and the room finally feels the way you wanted it to feel.
