I just converted over to NG and have yet to receive my first bill. I just checked my gas company's website to see what gas is going for and also to see what it costs when compared to oil. Here is the current pricing through my gas company: http://www.soconngas.com/MediaLibrary/2/3/Content Management/SCG/Your Business/PDFs and Docs/Rate RSH.pdf "RATE PER MONTH: (Ccf 100 cubic feet) (a) Delivery Service: Customer Charge: $13.00 Delivery Charge: First 30 Ccf : $0.9489 Per Ccf Over 30 Ccf : $0.3474 Per Ccf Sales Services Charge: $0.0363 Per Ccf" Now assuming 1 CF (Cubic Feet) of NG = Approximately 1,000 BTUs, 1 CCF = 100 CF = 1 Therm, and that one gal. of #2 oil has 139,000 btu. This means it takes 139 cu ft of NG to equal 1 gal. of #2 oil. So 139 cu ft = 1.39 CCF = 1 gal. of #2 oil, correct? So if I've historically used say 500 gal. of #2 per year for heating/DHW (and that my boiler efficiencies are unchanged), based on the above number this is equal to about 695 CCF of NG, correct? So assuming NG prices were fixed for the year (I know this is a poor assumption) and that I used a full 30 CCF each month of the year, are my figures bellow correct? ($13 x 12mo)+(30 CCF x 12mo x ($0.9489 + $0.0363)) = $510.67 for the first 360 CCF (or equivalent to 259 gal. of #2 oil). The remaining 335 CCF I use over the course of the year should cost me: (335 x ($0.3474 + $0.0363)) = $128.54. So I'm coming up with a yearly total of only $639.20 for the equivalent of 500 gal. of home heating oil. This seems very cheap, have a made a mistake somewhere??? If my math is correct, this works out to the equivalent to $1.28/gal. of #2 heating oil. Can this be correct?
