This would make it 12 cents an hour to operate. If you plug it in for 10 hours a day, it will be $1.20 a day.
I think a timer that turns it on a couple of hours before you plan to drive in the morning would be more economical. Then it would only use 2 kW/h per day in the morning.

So this means that you'd spend $438.00 a year in electricity on top of your usual operating costs..
Fuel at $2.40 per gallon = 182.5 gallons at 30 mpg = 5,475 miles..about half the annual milage covered by most people..some milage saving !
Well, maybe a little less engine wear too.
