Even though this unit is smaller than the others it’s 1500 watts vs the others with 1400. Not much of a difference but anything helps.
I have a 1400 watt infrared stove heater bought last year here on Woot! and it’s rated at 400 square feet. Somehow this one is rated at 1000 feet so who really knows
I also noticed that, out of the 3 for sale, this one is the only one that mentions having a blower fan. OTOH, the others have the fake flames, but you could bring up a YouTube fireplace video on an old tablet and place it nearby for ambience if that’s one of the factors in the buying decision.
A person could save some serious money while having a more effective blower heater and realistic crackling fire sound effects thru the tablet speaker.
These heaters are fantastic. i have two that I move around the house. Heats up the small guest rooms in no time and makes the larger rooms comfortable right away and toasty after an hour or so. Last one I bought on the mothership for $105.
