No hotspot, and my electric bill actually didn't go up much at all. Marginally. But I did insulate the heck outta the room before I went that route. Heater only turns on for about 2 mins at a time, maybe every 5-10 mins. Depending on how many times I go in or out of the room. Sometimes as long as 20-30 mins.
I like my Dubstep to go Wop Wop Wop Wop
