Touchstone Fireplug 38″ Electric Fireplace Insert

Best for converting existing fireplaces to a modern, fully electric unit. This insert is designed to fit openings around 36.75″ to 44″ with trim adjustments, providing a built-in look for existing masonry or prefab fireplaces. It features a realistic flame effect with a crackling sound option, plus a 1500W heater for supplemental heat. The unit supports a 110-120V outlet and can be hard-wired for in-wall installation. The 38″ width makes it a strong fit for standard 36–38 inch openings with trim customization.
Who it’s best for: Homeowners upgrading an existing wood or gas fireplace who want a seamless, built-in appearance with optional crackling sound and modern controls. This is a solid choice for multi-room living spaces where a wide viewing area is preferred.
Why selected: It combines realistic flames, optional audio ambience, and flexible installation in a recessed footprint, balancing ease of install with a wide visual flame. A potential limitation is the need for proper firebox opening adjustments and professional help for in-wall wiring in some homes.
Modern Ember Highmark Traditional 38 Inch Built-in Smart Fireplace Insert

Best for tech-forward homes that want voice control and vivid flame customization. This insert includes remote control and Wi-Fi with Alexa compatibility. It offers multiple flame colors, speeds, and brightness settings, along with a choice of ember bed colors. The heat can be set to a room temperature or left off for ambiance year-round. Realistic resin logs and crystal embers enhance the visual depth.
Who it’s best for: Buyers seeking smart-home integration and flexible ambiance options. It suits media rooms or living areas where lighting and temperature preferences vary by season.
Why selected: The broad color and flame-speed suite provides a highly customizable atmosphere. A limitation could be the need for reliable Wi-Fi connectivity to maximize smart features.
BVIUNTWO 38 Inch Electric Fireplace with Mantel

Best for a freestanding, mantel-inclusive setup with three-sided glass for a panoramic flame view. This model provides 3D flame effects with a log-and-ember bed, and a mantel that adds decorative space for media gear or decor. It also supports a heat function for comfortable room warmth during colder seasons and can operate with or without heat for ambiance.
Who it’s best for: Those wanting a stylish, freestanding unit that doubles as a media console or decorative focal point in a living room or bedroom.
Why selected: The three-sided glass display and hidden storage options make it a strong visual centerpiece. A potential limitation is that the size and mantel may require a larger room footprint and careful layout planning.
R.W.FLAME 36 Inch Recessed Electric Fireplace

Best for space-conscious rooms that still want a wide flame view. This recessed model measures 36 inches with a slim profile and supports two heating modes (750W and 1500W). It offers multiple flame color options, speed settings, and a timer. The compact footprint makes it a practical fit for bedrooms or smaller living spaces.
Who it’s best for: Buyers needing a recessed, slim option that preserves wall space while delivering a broad flame display.
Why selected: Its adjustable heat and color/speed options provide flexible ambiance control. Caution: Slightly narrower than a true 38″ unit, so it’s best matched to openings near 36 inches with precise measurements.
Electactic 36 Inch Electric Fireplace Insert Ultra-Thin

Best for ultra-thin wall installations where depth must stay minimal. This insert offers 750W and 1500W heating modes, 12 flame colors, and 12 ember bed colors, along with a timer and touch screen controls. It is designed to be nearly invisible in a modern wall setup, maximizing the flame display without a bulky frame.
Who it’s best for: Builders or renovators prioritizing a minimal profile with high customization for color and lighting.
Why selected: The ultra-thin design makes it ideal for wall projects where depth is a constraint. Caution: Some users may prefer a model with a larger viewing area for a true 38″ feel.
Buying Guide
- Fit and opening size: Measure your fireplace opening or wall space carefully. Inserts typically require precise width and height with trim allowances. Some models offer trim kits or adjustable tops to accommodate larger openings.
- Heat needs: Consider your climate and room size. Most 1500W models heat up to 400+ sq ft, while 750W options suit smaller spaces. If you only want ambiance, choose a model with heat off option.
- Flame realism and features: Look for flame color options, flame speeds, ember bed colors, and optional crackling sound. Some models include real logs or crystal embers for authentic visuals.
- Smart features and control: Decide whether you want remote control, app control, or voice integration with Alexa/Google Assistant. Wi-Fi-enabled units enable scheduling and remote adjustments.
- Installation considerations: Recessed in-wall inserts require electrical outlets or hard-wiring. Mantel units add decorative space but may demand more room planning. Professional installation is recommended for in-wall wiring and safety.
- Maintenance and safety: Ventless operation reduces smoke and ash, but ensure proper clearance from combustibles and follow manufacturer guidelines for usage. Look for cool-to-the-touch sides and automatic shutoff.
