10 Best Electric Fireplace Insert No Heat 2025 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 R.W.FLAME 36 inch electric fireplace is a sleek and modern option designed for wall mounting, fitting well within standard wall studs (2x4 or 2x6). Its ultra-thin depth of just under 4 inches makes it less bulky than older models, which is great if you want a flush, minimal look. The flame effect is highly customizable, offering 12 different colors and flame bed styles along with adjustable brightness and speed, controlled either by a remote or a touch screen. This gives you plenty of options to create a cozy, realistic ambiance without needing actual heat.

It has heating capability (up to 1500 watts) suitable for around 400 square feet, but it also functions well without heat, adding versatility. Safety features like ETL certification and auto-shutoff if it gets too hot provide peace of mind. The design includes a sleek black painted metal finish that fits modern interiors nicely. One minor drawback is that installation requires a proper wall opening between 31 and 35 inches wide, so some wall modification might be needed. While the flame effects are impressive for the price, they don’t perfectly mimic real flames, which could matter if you’re after maximum realism. The noise level is low, which is a plus for quiet environments.

This model is ideal for anyone looking for a stylish, energy-efficient fireplace insert to visually enhance a living room or common area without relying on heat. It’s especially useful if you want remote operation and customizable lighting effects. For those needing the fireplace mainly for heating large spaces or seeking ultra-realistic flame effects, other options might be more suitable.

The R.W.FLAME 42IN electric fireplace insert is a sleek and slim option that fits easily into wall-mounted spaces, thanks to its thin 3.86-inch depth. This makes it suitable for standard wall studs, either 2x4 or 2x6, which is helpful if you want a recessed look without taking up much room. It features adjustable flame colors and brightness with 12 LED flame modes and 5 speed settings, which gives a nice customizable flame effect that looks quite realistic. You can control it via a remote or a touch screen, adding convenience.

This fireplace offers heat with 750W and 1500W settings, and also supports a no-heat flame-only mode, perfect if you want the ambiance without warming the room. The design is modern with a black painted metal and tempered glass finish that looks clean and attractive. Safety is well addressed with ETL certification and an automatic shutoff to prevent overheating. However, the actual heating is best for smaller spaces up to about 400 square feet, so it might not suffice as a main heat source for larger rooms.

While the flame effect is adjustable and smooth, it operates quietly and focuses on aesthetics, so it may not fully replicate a traditional fireplace's warmth or crackle sound. This model is well suited for someone looking for a stylish, easy-to-install electric fireplace insert that prioritizes adjustable visual effects and safety over strong heating.
