The classic flame spectra fire infrared electric fireplace Insert not only looks like a wood-burning fireplace but also feels like one with its integrated quartz infrared heater. Capable of producing 5,200 BTUs of supplemental heat, you'll be able to warm areas as large as 1,000 sq. ft. This is typically more than enough heat to help keep the damp chill of winter at bay. The firebox includes a realistic log set that looks just as great when the unit is off as when it is on. The all LED-lit 3D spectra fire plus flame technology boasts a stunning fire appearance that appears to rise from in front of, between, and behind the log set. For a more contemporary look, the unit also comes with large glass crystals which can be used in place of the log set. Choose from 5 flame colors, 5 flame speeds, and 5 flame brightness levels to create a customized look. The unit also includes a multi-function remote control that allows you to adjust all the various settings from the comfort of your chair.
