cost of energy together with fluctuating natural gas and fuel oil prices have
raised questions at properties that have the ability to use natural gas and
either #2 or #6 oil regarding a cost comparison between fuels.
the most cost-effective fuel at any given time, do the following:
1. Check a natural gas bill
to determine the cost per therm of natural gas.
2. Multiply the above figure
by 10. Example .75 therm x 10 = $7.50
This is the cost per dekatherm.
3. If #2 oil is used,
multiply today’s price $1.1530 x 7.067 = $8.15. This is the equivalent cost
of a dekatherm of gas.
4. If #6 oil is used,
multiply today’s price .9819 x 6.689 = $6.57
This is the equivalent cost of a dekatherm of gas.
5. Another way of calculating
this would be:
There is approximately 40% more
BTU’s in a gallon of #2 oil than in a therm of natural gas. Take price per
therm and multiply by 1.4 to get equivalent cost of a gallon of #2 oil. (In
example above, .75 therm x 1.4 = $1.05 gal.
is approximately 46% more BTU’s in a gallon of #6 oil than in a therm of
natural gas. Take therm price and multiply by 1.46 to get equivalent cost of a
gallon of #6 oil.
above .75 per therm x $1.46 = $1.10 gal. Please not that you may use either
system 2, 3 and 4 - or 5 and 6. You don't have to use both.
For the above
examples, a dual fuel system using natural gas or #2 oil would save by using
natural gas. However, a dual fuel system would save using natural gas or #6 oil.
Prices should probably be checked weekly to determine the best price.
