10 Best Infrared Fireplace Insert Heater 2025 in the United States

The Duraflame Freestanding Electric Fireplace Stove Heater is a solid choice for adding warmth and ambiance to rooms up to 1,000 square feet. Its 5,200 BTU infrared heat efficiently supplements home heating, potentially lowering your energy bills by focusing warmth where it’s needed most. The unit’s size (about 24" wide, 13" deep, and 23.4" high) and freestanding design make it portable and easy to move between spaces. It features a charming bronze finish with side viewing windows and a glass door that opens, adding to a cozy, traditional look.

The realistic 3D flame effect with glowing logs is a highlight, offering adjustable brightness and the ability to run the flames without heat for year-round ambiance. The adjustable thermostat and flame controls are simple to use, letting you find a comfortable temperature and flame appearance. Safety-wise, it includes automatic timed shut-off, which helps prevent overheating.

Installation is straightforward since it’s freestanding and vent-free, requiring no special setup beyond plugging it in. Maintenance is minimal, mainly cleaning the glass and surfaces. The unit runs on standard electric power with 1,500 watts consumption, which is typical for heaters in this size class. Some limitations include the need for assembly and the reliance on batteries for the remote control, which may require occasional replacement. The heating capacity is suitable for medium-sized rooms but might not be enough for larger open spaces. The style leans traditional, so it may not fit all modern decors. This Duraflame heater offers a convenient, energy-conscious option for those wanting a portable infrared fireplace insert with attractive flame effects and user-friendly controls, well suited for living rooms or cozy areas up to 1,000 sq ft.

The Dimplex Revillusion 36" Built-in Firebox is a stylish and functional option for those looking to add both warmth and ambiance to their living space. It offers a heating capacity of up to around 4400 BTU, suitable for heating small to medium rooms efficiently. The unit’s size—just over 37 inches wide and about 12 inches deep—makes it a good fit for built-in installation in a variety of room layouts, whether centered or in a corner. One of its standout features is the Mirage Flame Panel, which creates a very realistic flame effect thanks to partially frosted acrylic that avoids unwanted reflections, enhancing the cozy atmosphere without the glare typical of many electric fireplaces.

This fireplace provides three power levels (1375, 1975, and 2575 watts), giving some flexibility in heating output and energy use. Installation is straightforward, as it can be surface-mounted and plugged in or recessed and hardwired, but it requires some care due to its weight (about 75 pounds) and hardwired power source. Safety-wise, it is vent-free and includes standard protections, but because it’s vent-free, good room ventilation is important. Maintenance is minimal since it uses LED flames and does not produce real combustion by-products. While it doesn't have a digital thermostat control, it allows you to adjust heat levels manually, which keeps things simple but might feel less convenient for some.

Combining elegant design with reliable heating and a visually appealing flame effect, this electric fireplace insert is a solid choice for anyone wanting a built-in solution that balances style and function.

The Touchstone Smart Electric Fireplace - The Sideline is a stylish and modern infrared fireplace insert designed for recessed in-wall installation. With a heating capacity of 1,500 watts, it can provide warmth to spaces up to 400 square feet, making it suitable for living rooms or bedrooms. One of its standout features is the realistic flame effect, offering 30 ember color and flame options, which can create a cozy atmosphere without the need for actual fire. Users will appreciate the convenience of controlling the fireplace through a remote, smart devices, or voice commands via Alexa or Google Home, enhancing user-friendliness.

Installation is straightforward, and the unit is ventless, meaning it doesn't require extensive ductwork. It stays cool to the touch on its sides and back, providing added safety, particularly in homes with children or pets. The option to run it with just the flame effect without heat is a great feature for warmer climates or ambiance without warmth.

While the Sideline can heat a room, it shouldn't be relied upon as a primary heat source. The heater is effective for taking the chill off, but larger spaces may require additional heating solutions. Additionally, the fireplace needs a minimum of 8 inches of clearance from televisions or mantels, which may limit installation options in some rooms. Another consideration is the use of two AAA batteries for the remote control, which aren't included, and those looking for a plug-in option will need to ensure they have the appropriate circuit, as the unit draws up to 12 amps.
