GAS BURNING APPLIANCE

COST PER HOUR CALCULATION

LP

1 gallon weighs 4.24 lbs.

1 gallon produces appoximately91,500 BTU

20 lb tank holds about 4.72 gallons

4.72 gallons produces about 432,000 BTU

Cost of a gallon in 100 lb and smaller tanks is about \$2.70 here in Dayton. In larger tanks it comes down to about \$2.10 per gallon.

YOUR COST MAY DIFFER SIGNIFICANTLY FROM THESE

At \$2.70 the cost per 1,000 BTU is \$.0295 (less than 3_)

“              “    10,000 BTU is \$.295 (less than 30_)

“              “    91,500 BTU is \$2.6992 (less than \$2.70)

At \$2.10 the cost per 1,000 BTU is \$.0229 (less than 2 1/3_)

“              “    10,000 BTU is \$.229 (less than 23_)

“              “    91,500 BTU is \$2.095 (\$2.10)

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.

 At \$2.70 Cost At \$2.10 Cost 90,000 BTU system \$2.65 \$2.06 150,000 BTU system \$4.42 \$3.43 270,000 BTU system \$7.96 \$6.18 415,000 BTU system \$12.24 \$9.50
