1gal. Propane = 91600 BTUs
1gal. Kerosene = 135000 BTUs
To heat 1,000,000 BTUs it would cost:
10.91 gals of Propane x (price per gal) = Cost (to heat 1mil btu)
7.4 gals of kerosene x (price per gal) = Cost (to heat 1mil btu)
Remember this is at 100% efficiency.
If you are working with something less efficient you must multiply the fuel btu by the efficiency.
For example:
Propane Furnace that is 80% efficient.
1,000,000 / (91600 x .8) = 13.6 gals
13.6 gals x (price per gal) = Cost (to heat 1mil btu)
Kerosene furnace that is 60% efficient.
1,000,000 / (135,000 x .6) = 12.3 gals
12.3 gals x (price per gal) = Cost (to heat 1mil btu)
Hope this helps
good luck
The biggest differece is in ther SPELLING and no. of LETTERS.
natural gas hv 10 digits and propane hv 7 digits
One pound of propane will produce 21,622 BTU's. 20 pounds of propane will produce 432,440 BTU's. A heater that produces 80,000 BTU's per hour will produce heat for almost 5 1/2 hours.
Type your answer here... there are around 91,600 BTUs in a gallon of propane. The standard BBQ sized bottle of propane contains 11 pounds of propane. Propane weighs about 4.2 pounds per gallon, so that 11 pounds of propane is about 2.5 gallons in its liquid state. That means there is 91,600 BTUs/Gal times 2.5 gallons so a BBQ sized tank of propane contains about 2.3 million BTUs. If your BBQ has a 50,000 BTU burner, on high heat, it will last a bit over 4 and half hours of run time.
$2.70 per gal
Approx 4.4 gallons per hour on full blast.
The price per gallon of propane is $3.16.
Yes. Kerosene has 140,000 btu's per gallon and gasoline has less.
Propane = 91,600 btu per gallon
propane has 21,548 BTU per pound so about 2 1/2 pounds per hour remember that propane is stored in a liquid and you need a big enough tank to allow the propane to change from a liquid to gas.
One pound of propane will produce 21,622 BTU's. 20 pounds of propane will produce 432,440 BTU's. A heater that produces 80,000 BTU's per hour will produce heat for almost 5 1/2 hours.
Natural gas= 1000 btu per cubic ft, propane =2500 btu per cubic ft and #2 fuel oil = 140,000 btu per gallon. Check the availability & prices in your area and you can figure your answer.

One gallon of kerosene will produce 134,000 BTUs of energy when burned.
There is approx 100,000 BTU per gallon of propane. A 100 lb propane tank holds approx 23 useable gallons. So that is 2,300,000 BTU. If the heater ran constantly burning 25,000 per hour that would be 92 hours straight.
the amount used with vary with different models of propane heaters, the volume of water being heated, and the amount of hot water used by the household.. the answer is not definative, but you might be able to get a rough idea by "googling" the manufacturer...
This depends on the cost per kilowatt hour in your area.
which is heavier Propane and Butane are _______ than air:
Propane has a heat content of 19,900 btu/lb net. This means that a 36000 btu/hr heater needs to burn 1.809 lbs of propane per hour to produce this amount of heat. A 40 lb bottle will last about 22 hours if the heater runs continuously.
