Five thousand BTU covers a room of about 400 sq ft, and the built-in thermostat holds it between 62 and 82 degrees rather than cycling between blast and off. Flame brightness runs on 3 levels, the timer offers seven settings from 30 minutes to 6 hours, and the blower stays under 50 dB so dialogue on the screen is not competing with it. The 58 x 16 x 32 in case surrounds a 24.17 x 5.10 x 17.52 in insert on a 6 ft cord, with the remote effective to 13 ft. Countertop rating is 66 lbs; shelves take 20 to 33 lbs by position. Total weight is 110 lbs.
