Thanks for finding that!
I only used my heat for about 6 hours the entire month. I don't see how I could have used 40 or 50 dollars worth of heat in 6 hours! Even if I used 100 kWh in that short time, that's only a hair over 7 dollars.
I'm going to just turn the breakers off to the entire apartment when I'm not home! lol
edit: seriously though, the month of february I'm going to experiment by not turning the heat on at all. Not one single time will my heat be turned on. Extra blankets and sweatpants here I come.
