February's bill is here.
February:
513 kWh
137 therms of natural gas
1174 heating degree days and 0 cooling degree days
29 day bill
Considering the time frame of this bill, I'm calling this marginally acceptable. I had hoped the attic insulation would contribute a bit more. Heating degree days went down by 35%, and actual billing days went down by 20%. Yet, gas therm use only went down 40%. Considering it was 35% warmer this really isn't great at all. According to
TimJFowler's formula, I dropped my consumption per heating degree day by a whopping 3.5%. It looks like I'll be looking into air infiltration as soon as I can.
