10 Best Electric Fireplace Inserts 2026 in the United States

The Touchstone Sideline 72" electric fireplace insert is a strong choice for anyone wanting a large, visually impressive fireplace that fits flush in a wall. At 72 inches wide and just 5.5 inches deep, it suits medium to large rooms and can easily replace or upgrade an existing fireplace opening. The realistic flame effect is a standout feature, offering 30 adjustable ember colors and flame intensities, which adds a cozy and authentic feel. You can customize it further by using logs, crystals, or a mix of both. Heating-wise, it provides up to 1500 watts (about 5000 BTUs), enough to comfortably warm up a space around 400 square feet, making it a good supplemental heat source but not a main heater. The heater vents face forward, so you can safely mount it just 8 inches below a TV. Installation is straightforward since the unit is ventless and designed for in-wall mounting; it can also be hardwired or plugged in. The sides and back stay cool to the touch, which improves safety.

For convenience, the Sideline comes with a remote, and smart features let you control it via Alexa or a mobile app, although it requires a WiFi setup and AAA batteries for the remote. Energy use is moderate, with a max draw of 12 amps, so it's best not to overload the circuit with other high-power devices. It is important to measure your space carefully before buying to ensure a perfect fit. While the flames look very realistic, the heating power won’t replace a central heating system in colder climates. Those wanting a stylish, modern electric fireplace that doubles as mood lighting and offers smart controls will find the Touchstone Sideline 72" delivers well, blending safety, efficiency, and aesthetic appeal.

The Dimplex IgniteXL 74" is a sleek, modern built-in electric fireplace designed to fit nicely in a variety of indoor settings such as living rooms, hotels, or restaurants. Its large size (over 74 inches wide) makes it a striking visual centerpiece. The standout feature is the Multi-Fire XD technology, which creates realistic, lively flames that can be customized in color and brightness, adding a cozy and attractive ambiance year-round.

Heating-wise, it delivers up to 5,118 BTUs, which can warm spaces up to about 1,000 square feet, making it suitable for medium to large rooms. Installation requires a hardwired connection (120V or 240V), with 240V providing the best heat output. Mounting hardware is not included, so some preparation is needed. The fireplace includes a remote control for easy adjustment of flame settings and temperature, supporting convenience and comfort. Its vent-free design and metal construction add safety and durability, though users should ensure proper installation by a professional due to electrical requirements.

This fireplace is energy efficient compared to traditional fireplaces and offers a good balance of heat and style. Its weight (over 100 pounds) and built-in nature mean it’s best suited for those committed to a fixed installation rather than a portable option. The product is ideal for anyone looking to add both warmth and modern flair to a sizeable indoor space, provided they are comfortable with the installation demands.

The Napoleon CLEARion 60-Inch Built-In See-Through Electric Fireplace is a stylish, contemporary insert that offers a unique two-sided, see-through design, making it great for adding ambiance to adjoining rooms. Its 60-inch width is quite large, so it's best suited for spacious areas or open layouts. Heating-wise, it provides up to 10,000 BTUs, which comfortably warms rooms up to about 800 square feet, making it suitable as a supplemental heat source rather than a primary heater for very large spaces. The flame effects are adjustable and come with crystal media and logs, which add to the visual appeal.

A notable feature is the Privacy Glass, allowing you to switch between transparent, semi-transparent, and opaque glass, giving you control over how much you want the flame to stand out or blend in. Installation requires direct wiring to 120V or 240V outlets and is designed for built-in setups, so professional installation might be needed. Energy efficiency is decent for an electric fireplace, with a vent-free design that minimizes heat loss. Safety features include a blower for even heat distribution and an adjustable thermostat to prevent overheating.

The included remote control adds convenience for adjusting heat and flame settings from across the room. One downside is the fairly heavy weight (over 170 pounds), which may make installation more challenging. Also, as it’s a premium model, the price might be higher than simpler inserts. If you want a modern, visually striking fireplace that also delivers reliable supplemental heating, the Napoleon CLEARion is a strong option, especially for larger living spaces.
