10 Best Electric Insert For Fireplace 2025 in the United States

The Dimplex IgniteXL 74" Built-in Linear Electric Fireplace is a stylish modern option designed to fit into a wall space, measuring roughly 74 inches wide and about 6 inches deep, making it suitable for medium to large rooms. It provides a decent heating capacity of about 5,118 BTUs, which should comfortably warm spaces up to 1,000 square feet, so it’s a good choice if you want supplemental heat rather than a primary heat source. One of its standout features is the Multi-Fire XD technology, which creates very realistic and vibrant flame effects with adjustable colors, enhancing the ambiance year-round even without heat.

Installation requires hard-wiring at either 120V or 240V, with 240V recommended for better heat output. It’s designed as a built-in unit, so some wall modification is needed, which might not be ideal if you want a quick setup. A remote control allows easy adjustment of flame settings and temperature, adding convenience. Energy-wise, it draws up to 2,500 watts at full power, so it’s not the most energy-saving option but typical for this size of electric fireplace.

Safety features include vent-free operation and a reputable design from Dimplex, which generally ensures reliable performance. On the downside, at 103 pounds, it’s quite heavy, and the mounting hardware isn’t included, so professional installation is recommended. Some users may find it less powerful compared to traditional fireplaces, but it avoids the mess and hassle of venting and fuel. This fireplace suits those wanting a large, visually impressive built-in electric model that adds heat and atmosphere to bigger living spaces, provided they’re prepared for a more involved installation and power requirements.

The Dimplex Revillusion 42 Inch Built-in Electric Firebox is a solid choice if you're looking for an electric insert that combines realistic visuals with effective supplemental heating. Its standout feature is the Revillusion flame technology, which creates flames that closely mimic a natural fire, enhanced by handcrafted faux logs and a herringbone brick interior that adds to the cozy, authentic look. The unit covers heating for up to 1,000 square feet, suitable for medium-sized living rooms, and you can turn the heater off if you just want the ambiance without heat.

Installation is relatively simple since it requires no venting, gas lines, or complicated setup—just plug it into a standard outlet or hardwire it for a cleaner appearance. The included multi-function remote adds convenience for controlling flames and heat from across the room. At just over 43 inches wide, it fits well in built-in spaces, but its depth of about 12 inches means you’ll need enough room behind your wall or cabinet.

With a weight of over 110 pounds, installation might require more than one person and some effort in handling. While the flame effect is impressive, purists looking for fully lifelike fire might notice it’s still a simulation. This electric insert suits those wanting easy installation, good heating coverage, and a very realistic flame effect without the hassle of venting or fuel, making it a practical and attractive addition to many homes.

The Touchstone Smart Electric Fireplace - The Sideline 36" offers a stylish and functional addition to any room, particularly benefiting those who want a cozy atmosphere without the hassle of traditional fireplaces. With 30 ember and flame options, it creates a realistic look that can enhance any home décor. The 1,500W heater can efficiently warm a room up to 400 square feet, making it suitable for living areas or bedrooms, although it won't replace a primary heat source entirely.

One of its strong points is the installation flexibility; it can be recessed into a wall or mounted on the surface, fitting seamlessly in existing fireplace openings. Plus, the ventless design ensures that you won’t need to worry about exhausting air or complicated venting systems, which can simplify setup. The fireplace is also equipped with smart features, allowing you to control it through Alexa, Google Home, or a mobile app, adding a modern touch to its operation.

However, there are a few considerations. The fireplace requires a minimum 8 inches of clearance from a TV or other heat-sensitive items, which may limit placement options in some rooms. While it provides a pleasant warmth, users need to keep in mind that it’s not intended to warm larger spaces or replace central heating. Some users might find the reliance on AAA batteries for the remote a bit inconvenient, as these are not included with the product.

The Touchstone Sideline Electric Fireplace is a great choice for those seeking a blend of ambiance and modern convenience, especially if you appreciate the aesthetic of a traditional fireplace without the maintenance. It's ideal for anyone looking to enhance their home environment while enjoying the benefits of a safe, ventless heating option.
