10 Best Electric Fireplaces For Large Rooms 2025 in the United States

The Touchstone Sideline Elite Pro 72" is a well-designed electric fireplace ideal for large rooms up to about 400 square feet. Its 1500W heater delivers decent warmth with an adjustable thermostat, making it a reliable supplemental heat source for living rooms or spacious offices. The fireplace offers flexible installation options — it can be wall-mounted or recessed, fitting neatly thanks to its slim profile and sizeable dimensions (72" wide). This makes it a stylish centerpiece that blends easily with modern decor.

One standout feature is its customizable flame effects: you get 6 flame colors, 13 downlighting colors, and realistic ember bed details like crushed glass and driftwood, all enhancing the ambiance beautifully. The built-in crackle sound adds a cozy, authentic fire experience. For ease of use, it supports smart home integration with Alexa and WiFi, allowing remote and voice control of flame settings, heat, and timers. This is a big plus for modern households. Energy-wise, the fireplace is vent-free and reasonably efficient for its size, but as with most electric heaters, it’s best seen as a supplementary heat source rather than a primary one.

The unit weighs 83 pounds and requires careful measurement before installation due to its size. A minor downside is that while it offers rich visual and sound effects, it may not generate enough heat for very large or poorly insulated rooms alone. Also, the price point tends to be higher than more basic models due to its premium features. Considering these points, the Sideline Elite Pro is an excellent option if you want a large, elegant electric fireplace with great ambiance, smart controls, and solid heating for large rooms, provided you plan your installation space carefully.

The Touchstone Sideline Elite Smart 60” electric fireplace is a strong choice for heating and decorating large rooms with its 1,500-watt heater capable of warming up to about 400 square feet. Its sizable 60-inch width and slim, recessed design fit neatly into walls, offering a modern and sleek look without taking up floor space. Installation is intended for in-wall mounting, which gives a clean finish but requires precise measurements and some DIY effort or professional help.

This model shines in creating ambiance with up to 60 flame and media color combinations, including realistic logs, driftwood, and crystals, all controllable via remote or smart devices. It also remembers your flame preferences and supports thermostat control between 68-88°F, so you can keep your room cozy without constantly adjusting it. Energy-wise, the 1,500-watt power use is typical for supplemental heating, but it’s not designed to replace central heating. Safety is enhanced by vent-free operation and heat vents positioned on the upper front, along with recommendations for clearance above the unit.

Control options are versatile, including a remote, smart device connectivity, and even operation through a wall switch. The fireplace requires 2 AAA batteries for the remote, which aren’t included, and the installation depth of about 5.5 inches means you need a suitable wall cavity. While the flame effects look impressive, some users might find the need for careful measuring and in-wall installation a bit challenging. This fireplace suits homeowners wanting a stylish, efficient heat source with strong ambiance in a living room or large bedroom who are comfortable with recessed installation.

The Dimplex IgniteXL Bold 100-in Electric Fireplace is a highly versatile and modern option for large rooms. Its installation flexibility allows you to set it up as a front-facing, right corner, left corner, or bay installation, which is ideal for various room layouts. It can be hardwired to either a 120-volt or 240-volt circuit for a clean, seamless look. This fireplace is capable of heating areas up to 1,000 sq ft, making it suitable for large spaces.

The ComfortSaver heating system ensures efficient heat distribution, while the Multi-Fire XD Flames provide a realistic and multi-layered flame effect that can be operated with or without heat, enhancing the ambiance of your room with both crystals and a driftwood log set. Additionally, the remote control and Flame Connect App offer convenient control options for heat output and other settings. The energy efficiency can be optimized with the eco mode.

The fireplace is vent-free, reducing installation complexity and potential safety issues related to ventilation. On the downside, the unit is quite heavy at over 220 pounds, which may complicate installation and relocation. Its high price point could be a concern for some buyers. Despite these drawbacks, the Dimplex IgniteXL Bold is a strong candidate for those seeking a stylish and effective heating solution for large rooms.
