Using the Fuel
Comparison Tool

To use this helpful fuel price comparison tool, you will need your last energy bill. First, find the type of fuel you use in the leftmost column, titled Fuel Type. Then, using your last energy bill, enter the bill total into Bill Total box in the correct row.
Then look for the total number of units of fuel you used. The example below shows a sample bill for Gas, which is measured in Therms. For this example, we would enter 19 into the box marked Therms. Oil is measured in gallons, as is Propane. If you use electricity, you'll need to enter the quantity of kilowatt-hours (KWH) used. Gas users please note: Do not use the rate quoted per Therm. This is irrelevant. The real cost of gas heat is measured to include all service charges, etc. That is why you enter the total amount billed, and the total Therms used, to get an accurate rating.
Finally, enter the approximate efficiency of your furnace, as a percentage. There's no need to use the % sign, however; just enter in the number. If you don't know your furnace's efficiency, just use 75, and it will still help you compare the different fuels against each other.
When you have finished, click "Calculate" to see your cost in dollars per kilowatt-hour appear in the rightmost column, titled Real Cost. The higher the number, the more expensive the energy source is at this time.
To compare this fuel with a different fuel, simply fill out another row in the form and click "Calculate" and compare the two costs. You can compare as many different fuels as you like, and you can change the numbers and then click "Calculate" again to get a new total. Or, you can compare your current furnace to a new furnace by changing the efficiency rating.
Summary:
If you have a dual-fuel furnace, the chart and indicator above can help you determine when you can save money by switching fuel sources. If you are considering changing from one fuel to another, or installing a newer, more efficient furnace, you can use the chart to see if you would be better off with oil, gas or propane at the new efficiency level.
