I can't afford this.

Why does my electric furnace use twice as much energy as my neighbor's? I live in a townhome development and we have the same floor plan.

My electric bill for the past two months has been $400 each month and I can't figure out why. I live a roughly 1900 sq ft townhome that is new; construction finished around October 2008. My neighbor's electric bill was about $200 over the last month. The only relevant difference I can think of is that I have the end unit in our row and he doesn't. I keep the heat set at 66 degrees in the house and the average temperature in my city was 41 degrees in December, for what it's worth.
I have been checking my meter since I got my latest bill and I am on pace for another $400 bill this month. Through switching breakers off and the process of elimination, I determined that the heater is the issue. I averaged about 5 kwh per hour of electric usage over the last couple months, compared to 1kwh per hour when I shut off the heat or cut the breaker. There was one hour where the heater was running full-time to re-heat the house after cutting the heat off and that used 16kwh for that hour.
My neighbor is using about 2.5 kwh per hour on his last bill compared to my 5kwh.
My heater isn't blowing all the time, but when it does it uses an insane amount of power.
Is my end unit the culprit? I have a hard time imagining that it would cause me to double my heating costs. Does it make sense that my heating unit would draw more power than it should when it's running, but no power when it's not?
Oh, and a final data point. I was not the first person to move in to my section of townhomes, and the other end unit was occupied well before mine. My electric meter is reading more than twice is high than everyone else's. If it was an increased bill due to having the end unit, the other end unit would have a reading like mine, wouldn't it?
