The Dimplex Revillusion 36 Inch Built-in Electric Firebox is designed to provide both aesthetic appeal and functional heating, making it a solid choice for large rooms. One of its standout features is the Revillusion Flame Technology, which creates a lifelike flame effect, enhanced by mood lighting options in blue or red. This can add a cozy atmosphere to any space. With a heating capacity of up to 8,794 BTUs, it effectively serves as a supplemental heat source, making it suitable for larger living areas.

In terms of size, the firebox has a depth of 12.07 inches and a width of 37.17 inches, which allows for a built-in installation that can save floor space. The decorative brick surround adds a stylish element, complementing various interior designs. It also comes with a multi-function remote control, providing convenience when adjusting settings or flame intensity.

On the downside, the installation type is built-in, which may require more effort and planning compared to portable options. It also needs to be hardwired, so professional installation may be necessary unless you're experienced with electrical work. Additionally, while it offers a good heat output, it functions best as a supplemental heat source rather than a primary one. Safety features are adequate, but it’s advisable to ensure that the firebox is positioned correctly and not obstructed. Its energy consumption is rated at 2503 watts, which, while reasonable, could affect electricity bills if used frequently.
