This electric fireplace insert delivers 5120 BTU of infrared quartz heat across roughly 1000 sq.ft., managed by a thermostat that holds between 70 and 95 degrees Fahrenheit. Control runs three ways through the app, a voice assistant or the remote, with Alexa and Google Assistant both supported. Resin lemon-wood logs sit behind the glass for a convincing bed, five flame options and five brightness levels adjust the look, and a 0.5 to 8 hour timer handles bedtime.
