YOUR COSTS MAY DIFFER SIGNIFICANTLY FROM THESE

To calculate:

  1. Divide the cost per gallon by the number of BTU produced by a gallon. This will give you the cost for 1 BTU
  2. Multiply this result by 10,000 to get the cost per 10,000 BTU.
  3. To determine the cost per hour – Multiply the cost for 10,000 BTU by the number of 10,000 BTU segments there are in the BTU rating of your appliance.

 

Example: A 90,000 BTU appliance has 9. Multiply the 10,000 BTU cost by 9.

                A 150,000 BTU appliance has 15. Multiply the 10,000 BTU cost by 15.
