I purchased 2 weeks ago and explained the room was under the stairs and fairly open - it is smallish room though. I ran it pretty much all day yesterday (10 hours) - on max/ 6 - without the fan which gets too noisy other than at the start when I have it on. It does pump out heat if you are standing above it but it's definitely no good for this sort of room which has open areas on two sides and no door. In a bedroom or living area where you can close the area off might be okay. I'm off to buy another radiant heater to replace the one which broke after many years of good service and which seems to work better in my living room or at least make you feel warm!
