36-Inch Electric Fireplace Insert with Sound

★★★★☆ 4.9 (31 reviews)

Standard masonry fireboxes tend to land in the mid-thirties, which is exactly the gap this 36-inch insert fills. It needs an opening 32.4-35.5" wide, 25.7-26.8" high, and 8.5" deep at minimum, with overall dimensions of 36"W × 27"H × 8.9"D. Nothing to mount and nothing to vent, so it sits in the opening, plugs into a standard outlet, and works. The flame is the reason to pick it. Twelve flame colors, 12 ember bed colors, and a top ambient light each run independently across five speed and brightness settings, layered over a simulated firewood crackle. Customers describe it as beautiful and very real looking, and at 45.3 pounds it's manageable enough for one person to position with care. Heating covers up to 450 square feet at 750W or 1500W, with an Eco mode that adjusts power and fan speed against room temperature so you're not micromanaging a dial. The 60-99°F thermostat, 0.5-9 hour timer, and digital readout are reachable by remote or by the onboard buttons. CSA certified with child lock and passive overheat protection, and it runs flame-only when the heat isn't welcome. One-year warranty, with support that answers year-round.
