Yep, that is what I run. Measured it the other day, on a killawatt meter, while breaking in my new inverter. 280W? something like that. I might need to find one with a high/low setting, sometimes all I need is a gentle warm breeze.Have you tried an electric throw? I know they all have crap reviews, but I’ve been doing OK. I think they’re all around 100W and they out the heat right on you. Hand warmers are key, too!
Having a throw rug beneath my feet helped, basement floor is concrete of course, with some thin flooring on it. Having two computers running around the clock keeps the room warm, but not the floor, go figure.
