A gallon of jet fuel supplies 126,000 BTU. So...a million BTU is less than 8 gallons.
Propane = 91,600 btu per gallon
To calculate the BTU needed to heat 10 gallons of water from 32°F to 212°F, you can use the formula: BTU = gallons × 8.34 (weight of water per gallon in pounds) × temperature change (in °F). The temperature change is 212°F - 32°F = 180°F. Thus, BTU = 10 gallons × 8.34 lbs/gallon × 180°F = 15,012 BTU.
#2 fuel oil = 140,000 btu per gallon/10 =14000 btu X 2 =28000 btu
Recommend 400,000 BTU heater
You need to know eactly how many gallons and btu that require for your home.
There is a total of 8 atoms in Ethane.
answer: 7680 btu 1 gallon= 8 lb 130F-50F=80F 12G*8LB*80F=7680 BTU
400k btu
About 0.43 US gallons of oil.
If there are 93,000 btu's per gallon of propane, and you are burning 25,000 per hour. That would be 3.72 hours per gallon or approx .27 gallons per hour. 6.45 gallons per day.
Standard bath is taken to be 20 gallons at 8.35 pounds per gallon and 60 degrees F of heating = 10,000 BTU per bath in round numbers, assuming 100% efficiency water heating.
