There Are Normally 4785 Heating Degree Days a Year
So, divide by three and that's your projected annualized cost of heating your home:
4785/3 = $1,595
(Don't ask why, but it is all spelled out below under "Heating Degree Days."
Based on Duke's filings for January I'm raising my normalized cost $300 to $1,895 on an annual basis -- for one house.
