Key takeaways
- Measure twice: Record the opening width, height, depth, and available clearance. A trim frame can hide small gaps, but it cannot fix an insert that is too large.
- Match heat to the room: Most 1,500-watt models are supplemental heaters for a modest room, while 750-watt mode is useful for gentler warmth and lower electrical demand.
- Plan the controls: Remote controls are convenient, while Wi-Fi and app support are worthwhile if you want schedules or smart-home integration. Physical buttons remain valuable when the remote disappears.
- Inspect the flame system: Adjustable brightness, flame colors, ember effects, logs, crystals, and fuel-bed lighting all change the look. More settings are not automatically more realistic.
- Think like an installer: Check outlet placement, ventilation guidance, mounting hardware, timer behavior, thermostat operation, and overheat protection before closing up a wall or mantel.
What's inside
Choosing an electric fireplace insert is less about chasing the biggest flame display and more about fitting a convincing, useful heater into the space you already have. Cabinet openings are rarely perfectly standard, wiring can be awkward, and a unit that looks excellent in a listing may be noisy, shallow, or underwhelming once installed.
This guide takes a practical DIY-maker view of the current field. I’m looking at installation flexibility, heat output, controls, flame customization, noise, and everyday usability—not just how dramatic the product photos appear. Measure the opening first, confirm your circuit can handle the heater, and treat flame effects as ambiance rather than a substitute for whole-room heating.

The Best Electric Fireplace Insert Heaters (2026) Reviewed
Best Overall: Touchstone Sideline 50-Inch Smart Insert
The Touchstone Smart Electric Fireplace—The Sideline 50″ combines a broad recessed design with Wi-Fi, Alexa compatibility, a thermostat, and a substantial selection of ember and flame effects. Its log and crystal hearth options make it especially adaptable during a remodel, though its 50-inch width demands careful framing and a properly planned electrical route.
Best for Maximum Visual Customization: 65-Inch App-Controlled Insert
This 65″ Electric Fireplace Insert offers wall-mounted or recessed installation, app and remote control, and 13 flame and fuel-bed colors. It is a strong choice for a media-wall project where the fireplace needs to act as a visual anchor, but measure the wall carefully and confirm that the extra width will not overwhelm nearby furniture.
Best Traditional Log-Set Look: PuraFlame Western
The PuraFlame Western Electric Fireplace Insert keeps the design familiar with a black surround, log-focused presentation, remote control, and a fire-crackling sound feature. At roughly 33 1/16 inches wide by 25 9/16 inches high, it is a sensible candidate for updating an existing fireplace opening without building an oversized feature wall.
Best Freestanding Conversion: 24.5-Inch Wi-Fi Log Set
This 24.5″ WiFi Freestanding Electric Fireplace Log Set is made for a different kind of DIY project: placing a compact insert inside an existing hearth or fireplace cavity without committing to a full recessed installation. App control, a nine-hour timer, thermostat, multiple flame colors, and adjustable brightness give it useful flexibility for rental-friendly or reversible upgrades.
Best Compact Insert: 23-Inch Low-Noise Model
The 23″ Electric Fireplace Insert is a straightforward option for smaller openings, with a log set, remote, four flame-brightness levels, an eight-hour timer, and overheating protection. Its 1,400-watt heater is slightly below the common 1,500-watt class, which can be helpful where electrical capacity is a concern; the compact dimensions still need to be checked against the opening and trim.
Frequently Asked Questions
Can an electric fireplace insert heat a whole room?
Usually, it is best viewed as supplemental heat. A typical 1,400- or 1,500-watt heater can make a noticeable difference in a reasonably sized, closed room, but insulation, ceiling height, drafts, and the room’s existing heating system matter just as much as the advertised wattage.
Is recessed installation difficult for a DIYer?
The carpentry is often manageable, but electrical work deserves more care. Use an appropriate outlet and circuit, follow the manufacturer’s clearance requirements, avoid pinching cords behind the unit, and hire a qualified electrician when new wiring or hardwiring is involved.
Can I use the flame effect without turning on the heat?
Most electric inserts are designed to operate the flame display independently from the heater. That makes them useful year-round, but verify the control layout before installation so you can disable heat easily from the remote or touch panel.
Are smart fireplace inserts worth the extra cost?
They can be, particularly when the fireplace is part of a media wall or daily routine. Wi-Fi adds scheduling and voice-control convenience, but a reliable remote and physical controls may be the better value if you rarely automate household devices.
Final Thoughts
For a polished built-in project, the Touchstone Sideline is the most feature-rich pick, while the PuraFlame Western suits a classic hearth makeover. Choose the compact 23-inch model for tighter openings, or the freestanding Wi-Fi log set when you want a less permanent installation.
