10 Best Infrared Fireplace Insert Heater 2025 in the United States

The Touchstone Sideline Elite Smart 60” Electric Fireplace is a stylish option designed for in-wall installation, making it suitable for modern homes. Its sleek black frame and large flame viewing area contribute to its aesthetic appeal, while the realistic flame effect, featuring 60 color combinations and various intensity settings, enhances the cozy atmosphere traditionally found in fireplaces. The unit operates with a heating capacity of 1,500 watts, providing supplemental heat with adjustable thermostat settings ranging from 68 to 88 degrees Fahrenheit, which allows users to customize their comfort level. Additionally, it supports both plug-in and hardwired installation, offering flexibility based on your home’s needs.

On the flip side, while the installation is user-friendly, it may still require some basic DIY skills, which could be a hurdle for some homeowners. The 5 1/2-inch depth is relatively slim, but it’s crucial to ensure there is adequate wall space for proper placement and ventilation. The remote control feature adds convenience, though it's important to note that batteries are not included. Furthermore, while it provides a nice range of flame colors and effects, some users might find that the heater's output is more suitable for small to medium rooms, making it less effective in larger spaces.

The Touchstone Sideline stands out for its advanced features, including smart device compatibility and flame memory settings, which enhance user experience. However, as with any electric heater, relying solely on it for primary heating might not be ideal during extremely cold weather. With its combination of beauty and functionality, this fireplace is an excellent choice for anyone looking to upgrade their living space while enjoying the ambiance of a real flame.

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.
