Basically 1 BTU will move 1 pound of water 1 degree Fahrenheit. There are 8.35 lbs in 1 gallon. There are 8.35*5=41.75 lbs in 5 gallons. To take water from 75 to 212 therefore requires: (212-75)*41.75=5720 BTU.

How many BTU does it take to boil 1 gallon of water?

One BTU is the amount of heat energy required to raise one pound of water by 1ºF. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1ºF.

How much energy does it take to boil 1 gallon of water?

Water requires the input of 4.2 KJ to raise each kilogram by 1 degree centigrade. A gallon of water weighs 3.79 kilograms. Assuming you’re raising it from 20C to 100C, the energy required is 4.2 KJ * 3.79 kg * 80C = 1273.44 KJ, or roughly one-third of a kilowatt-hour to bring the water to a boil.

How many BTU do I need for brewing?
