The Prism Insert

The Prism Insert 1400W electric fireplace insert. 23 inches wide with three selectable flame colors (amber, blue, purple) at 3 brightness levels each. 5,000 BTU. 400 sq ft coverage. White handheld remote plus front-panel touch controls. Drops into an existing masonry fireplace opening, TV console cutout, or cabinet opening — or sits freestanding on a hearth stone. Quiet operation. ETL certified. We'll say it before you do Every 1500W-class electric fireplace on the market makes essentially the same heat. Ours, the one at the big-box store, the one your neighbor bought online — watts in equals BTU out. Anyone telling you their fireplace is "more efficient" is selling you a story. What actually differs about The Prism Insert is the flame options. Most electric inserts give you a single amber flame effect. The Prism gives you three: the traditional amber log flame, a cool blue flame, and a purple flame — each at 3 brightness levels. Amber every night if that's what you want. Blue when the room feels too warm-toned. Purple in October if that's your thing. Not what you bought a fireplace for, maybe. Turns out it's worth it. And where it fits. This is not a wall-mount modern panel like the Crystal Panel line. This is an insert. It drops into the rectangular opening you already have — the masonry fireplace surround that has sat sealed and empty since the last chimney inspection, the TV console with the factory-made fireplace cutout you never bought the insert for, the built-in cabinet with a fireplace-shaped hole your carpenter left for you. Or it sits freestanding on a flat hearth stone with nothing holding it down but its own weight. No wall-mount bracket. No drywall to cut. No contractor. What Actually Differs 23 inches wide, 18 inches tall, 7 inches deep. Sized to drop into standard mid-width rectangular openings that already exist in a lot of homes: 1970s-1990s masonry fireplace surrounds, factory-cut TV console cutouts, and modular cabinet openings sized for a 23-inch insert. Measure your existing opening. If it's at least 23" wide, 18" tall, and 7" deep, this fits. Mounting flanges on the corners let you screw it into a wooden surround if you want it locked in — otherwise gravity holds it in place. Three selectable flame colors, 3 brightness levels each. The Prism Insert lights the log bed in amber (the traditional log-fire look), blue (a cool contemporary mood), or purple (a stylized decorative effect no other insert in this class offers). Each color has 3 brightness settings: low for evening ambience, medium for a normal-looking fire, high for full glow. Switch between them from the couch with the white handheld remote. Realistic amber log-flame effect. Molded resin log bed with LED backlighting behind tempered glass. The amber flame is convincing at normal viewing distance in evening light — the primary setting most people leave it on. It is still an LED effect — no wood, no smoke, no smell. 1400W. 5,000 BTU. 400 sq ft coverage. Same effective heating power as most 1500W-class competitors. Rated to warm a well-insulated 400 sq ft room to comfortable temperature. In a drafty 800 sq ft great room, the Prism will feel warmer near it but the far corners will still need your regular heat. Quiet operation. Low background fan noise — quiet enough to hear the TV over without turning it up. Noise level is a spec most fireplace listings hide because most inserts in this class are louder than they let on. White handheld remote + touch panel. That's it. Small white handheld remote for the couch. Touch buttons on the top strip for flame color, brightness, power, timer, and thermostat. Adjustable thermostat 62°F–82°F. 0.5–7.5 hour timer in half-hour increments. No phone app. No WiFi setup. No Alexa configuration. No cloud account. If you have felt like every appliance in your house has become a Bluetooth-pairing exercise, that absence is the point. Overheat shutoff. Cool-touch tempered glass. ETL certified. Element cycles down automatically if the housing overheats. Tempered glass front stays cool to touch. Iron and steel housing. Front-strip vent moves warm air out the top so nothing hot faces the room. Full ETL certification — the same certification the brand-name inserts carry. Perfect For An existing masonry fireplace surround that has been sealed off and sitting empty (any opening at least 23" × 18" × 7"). A TV media console with a factory-made rectangular fireplace-insert cutout in the middle. A built-in cabinet or bookshelf with an opening around the right size. Freestanding on a flat hearth stone, raised stone platform, or slate ledge. A small-to-medium room, home office, guest bedroom, or cabin — anywhere 300–400 sq ft with an outlet nearby. Rental apartments where you can't modify the wall but there's an existing decorative fireplace opening. Anyone who wants flame-color options — amber for every day, blue or purple when you want the room to feel different. People who want a fireplace without an app, cloud account, or WiFi setup.

There is no wall-mount bracket in the box. If you have a bare wall and want a modern flat panel hanging on it, this is not the right product — look at The Crystal Panel line instead. This is an insert designed to drop into an existing rectangular opening. It is not warmer than a competitor's 1500W insert. Same class of heater core. If you need to warm a larger room, this doesn't do that — a single 1400W unit warms a well-insulated 300–400 sq ft room, no more. For a bigger room you need central heat or a second unit. It is not smart-home compatible. No app. No WiFi. No Alexa integration. No IFTTT triggers. Remote and top-panel touch buttons only. If you want to say "Alexa, turn on the fireplace," this doesn't do that — look at The Crystal Panel line. The blue and purple flames are stylized, not realistic. The amber flame is convincing at normal viewing distance in evening light. Blue and purple do not attempt to look like real fire — they read as decorative colored light. If you want ONLY realistic flame every night, amber-only inserts like The Firebox or The Brickstone are fine choices too. It is not a real fire. The molded log bed and colored flame effect look good at normal viewing distance, but it is an LED-lit visual effect. No wood, no smoke, no crackling, no chimney draw. It should not be left running unattended in heat mode. The overheat shutoff and 0.5–7.5 hour timer exist because unattended space-heater use is how house fires happen. Use the timer. Never leave heat mode on when you leave the house or go to sleep. Flame-only mode (no heat, ~12W draw) is safe to leave overnight. It draws roughly 12A at 1400W. Plug directly into a wall outlet on its own circuit, not a power strip or extension cord. If the outlet is on a shared circuit with a microwave or window AC, you'll trip the breaker. It does not fit every opening. Measure yours: 23" wide × 18" tall × 7" deep minimum. A too-small opening will not accommodate this. If your opening is narrower, look at The Firebox at 18" wide instead. If your opening is 26+ inches and you want a matching brick interior, look at The Brickstone. Check before ordering.
