10 Best Electric Fireplace Insert No Heat 2026 in the United States

The R.W.FLAME 68 inch electric fireplace is a sleek, ultra-thin unit designed to fit flush within a wall or recessed space, making it a good option for rooms where space is tight or a clean look is desired. Its slim depth of just under 4 inches makes installation easier in standard 2x6 stud walls. You can control the fireplace either via a touch screen or a remote, offering convenience and flexibility. The flame effects are notable with 12 different color options and adjustable brightness and speed, allowing you to create a cozy or vibrant ambiance. This electric insert also features an automatic flame mode that shifts colors and brightness for a more natural flame look.

Although it provides heat with two adjustable power settings, its main appeal is the visual effect, fitting the category of non-primary heat electric fireplaces well. The unit is ETL certified, ensuring safety with an auto-shutoff feature to prevent overheating. The design is contemporary and practical, featuring a black painted metal frame that should blend into most interior styles. It covers a heating area of up to 400 square feet, suitable for medium-sized rooms but may not replace central heating.

One downside is its weight, around 64 pounds, which could make installation a bit challenging without help. This fireplace insert is a solid choice if you want a stylish, low-noise flame effect with optional gentle warmth, especially for living rooms or similar spaces.

The Dimplex Revillusion 42 Inch Built-in Electric Firebox offers a visually appealing option for those looking to add ambiance to their living space without the need for actual heating. The size and dimensions (12.13"D x 43.25"W x 26.63"H) make it a substantial addition to any room. Its standout feature is the revillusion flame technology, which creates a very realistic flame effect. The herringbone brick interior with natural soot markings enhances its authentic look and feel, supported by the realistic faux log set molded from real wood.

The front glass panel further adds to the visual appeal, making the flames look like they are dancing around the logs naturally. Installation is flexible, with the included 120V plug kit allowing for either a plug-in or hardwired setup, which can help achieve a cleaner look depending on user preference. The control options include a multi-function remote, making it convenient to operate. The design and finish, featuring a painted metal build and a brick interior, add a touch of elegance and sophistication to the room.

Additional features such as the corded special feature and vent-free ventilation type make installation and use straightforward. At 112.7 pounds, it is quite heavy, which may require assistance during installation. Also, while it can provide heating for up to 1,000 square feet, the heater can be deactivated, which is ideal since the category focus is on no-heat electric fireplace inserts. Its weight and popularity might be points to consider.

The Dimplex Revillusion 36 Inch Built-in Electric Firebox offers a visually striking flame experience with its specialty Revillusion flame technology, which mimics natural fire very realistically. Its 36-inch size fits well into many spaces, and the herringbone brick background with natural soot details adds an authentic touch to the look. Installation is flexible—you can simply plug it into a standard outlet using the included 120V plug kit or choose to hardwire it for a cleaner appearance, making it suitable for various room setups without needing gas lines or venting.

The insert comes with beautifully handcrafted faux logs that look like real wood, enhancing the cozy fire illusion. Controls are straightforward, and the unit includes a remote for easy operation. While it includes a ceramic heater capable of warming spaces up to 1,000 square feet, this heat function can be turned off if you want just the flame effect without warmth, which fits this category well. The unit weighs about 30 pounds and is designed to be built-in with a painted finish that complements the brick-style design.

One consideration might be the somewhat limited color options—mainly brick tones—and the need to consider the 12-inch depth to ensure it fits your space. While it’s excellent for creating ambiance, the heat output, although sufficient for small to medium rooms, may not replace a main heating source. If you want a stylish, easy-to-install electric insert that offers both heat and a convincing flame effect, this Dimplex model is a strong choice that balances aesthetics and function.
