10 Best Electric Fireplace Inserts 2025 in the United States

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 Touchstone Smart Electric Fireplace - Sideline 36" is an excellent choice for those looking to add a stylish and functional electric fireplace to their home. Its recessed design allows for a clean, modern look, making it a great fit for living rooms or bedrooms. One of the standout features is its realistic flame effect, which includes 30 ember color/flame options that can create a cozy atmosphere or a more dramatic effect depending on your preference.

In terms of heating, this unit offers a decent heating capacity of 1,500W, which is suitable for rooms up to 400 square feet. It can warm a cool space, but it should not be relied upon as a primary heat source. The remote control and smart features, including compatibility with Alexa and Google Home, enhance convenience by allowing you to adjust settings from your couch or even via your smartphone.

Installation is straightforward, as it can be mounted in a wall or used in an existing fireplace opening. The unit is also ventless, which means it won't require any chimney or external venting, making it a flexible option for various home designs. Additionally, it remains cool to the touch on the sides and back, enhancing safety, especially in homes with children or pets. Some users may find the heating output a bit limited compared to traditional fireplaces, especially in larger spaces. The requirement for 8 inches of clearance from a TV is also something to consider when planning your installation. Lastly, it operates on a maximum of 12 amps, so ensure your electrical circuits can handle that alongside other devices.

The Dimplex Revillusion 42 Inch Built-in Electric Firebox is a solid choice for those wanting a realistic-looking electric fireplace insert that fits into a built-in setup. Its 42-inch size is fairly standard, making it suitable for medium to larger living rooms. The standout feature is the Revillusion flame technology, which creates flames that look much more natural compared to typical electric fireplaces, especially combined with the handcrafted faux logs and the weathered concrete interior for added realism.

Heating-wise, this firebox can warm up to 1,000 square feet, which covers an average-sized room efficiently. It uses a ceramic heater that provides about 5,118 BTUs—enough to supplement your main heating system comfortably. The heater can also be turned off if you want just the flame ambiance without heat. Installation is straightforward since it doesn’t need venting, gas lines, or complex tools. The included 120V plug kit means you can plug it into a standard outlet right away or hardwire it for a cleaner look. This flexibility helps with various installation preferences. It’s designed for built-in placement, either centered or in a corner.

The firebox is relatively heavy at over 110 pounds, so installation may require some help. While the flame effect is impressive, it may be less bright in very sunny rooms. The price reflects its advanced flame technology and realistic design. This Dimplex Revillusion firebox suits anyone wanting a visually appealing, built-in electric fireplace with good heating power and flexible installation options. It combines style and function nicely but may require a bit of effort to install due to its weight.
