Luku 72 Inch Ultra-Thin Electric Fireplace Insert — 750/1500W Linear Heater, Wall-Mount or Recessed, Adjustable 12-Color Flame, Timer 1-8 Hours

Sleek, ultra-slim 72-inch electric fireplace insert from Luku designed to fit flush into a wall or be used freestanding. The upgraded linear heater delivers selectable 750/1500W output and is sized to warm areas up to 400 square feet. A digital thermostat provides nine temperature settings between 60°F and 99°F for precise climate control without the need for venting or complex installation—offering the convenience of a fireplace without the usual maintenance. Visual and audio effects include 12 selectable flame colors and 13 ember bed lighting options that can be combined to create custom looks. Flame intensity is adjustable, with five distinct movement patterns and optional crackling sound effects offered at three volume levels to enhance realism. The unit includes a 1–8 hour programmable timer for automatic shutoff. Everything required for setup is supplied: the slim fireplace unit, remote control, and complete mounting hardware. The minimalist appearance complements traditional and contemporary interiors while eliminating the space and upkeep of a conventional hearth. Versatile 3-in-1 use as freestanding, wall-mounted, or recessed insert makes it suitable for living rooms, bedrooms, dining rooms, offices, home theaters, and RVs. Built with heat-resistant steel glass and an automatic overheat cutoff at 212°F (requires a 5-minute cool-down before restarting) for added safety.
