This just wasn't what I expected.  I don't know whether to blame the device and take it back, or blame the high ceilings in my house.  I do know that I've set the thermometer on the device to high and it can stay on continuously and never reach the high temperature. 

I like the remote control feature, I don't have to put my feet on the cold floor to turn it off in the middle of the night.

 It doesn't radiate heat for a long distance, you can stand inches in front of it and not feel heat.  Wonder if my device is defective?
