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 many BTUs Do I need to boil water?
You have all heard of the BTU of heat energy (British Thermal Unit), it takes one BTU to raise one pound of water one degree Fahrenheit. So if the water in the pan on the stove is put in at 32°F, it will then require 180 BTU’s to bring the water to boiling temperature, or 212°F.
How many BTUs Do I need to boil 5 gallons of water?
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 BTUs does it take to boil 1 pound of water?
That one pound of water must absorb 970 Btu’s before it all turns to steam, and will stay at 212°F during the process. That’s one match required to raise the temperature by one degree, and then almost 1,000 matches to boil off the water while not raising the temperature.
How many BTU’s can a gallon of water absorb when it is taken from 62 F and turned into steam?
It is the process of vaporization that water exerts its maximum cooling action; one gallon of water will absorb approximately 1,250 BTU’s going from 62 Degrees F to 212 degrees F.
How many BTUs does it take to raise 1 degree?
It takes 0.24 BTU of heat to change the temperature of one pound of air by one degree F.
How many BTUs do I need to deep fry?
But be sure you get a unit with something in the neighborhood of 30,000 B.T.U.’s. This provides enough juice so that when frying, you can get oil back up to heat very quickly. This means you can cook for a big crowd, which is kind of the point of the exercise. Once you have the power, you will need the pan.
How long does it take to boil 6 gallons of water?
Depends on the BTU output of the burner, and a few other variables. Looks like that’s a Dark Star? If so, that’s comparable to the SQ14 I used to use. With that, it would take me about 45-50 minutes to get 6 or 7 gallons from room temp to a boil, and about 20-25 to go from mash temps to a boil.
Is 18000 Btu enough for cooking?
Middle: 2,000–10,000 BTUs. Mid-range BTUs are good for everyday cooking like sauteing and frying. High: 12,000–18,000 BTUs. These high BTU burners are meant for high heat cooking like searing and stir-frying.
What hotter boiling water or steam?
Boiling water is a saturated liquid vapor mixture but steam is either a saturated vapor or a superheated vapor. Steam can be superheated only when the applied temperature is greater than the saturated temperature for a given pressure. Hence steam is always hotter than boiling water.
How hot can steam get under pressure?
Example: The temperature of 250 psig pure steam is always 406°F. Heat of Saturated Liquid (Column 4). This is the amount of heat required to raise the temperature of a pound of water from 32°F to the boiling point at the pressure and temperature shown. It is expressed in British thermal units (Btu).
How many BTUs would you need to raise 45 pounds of water 18?
Using the same logic, you can heat 45 pounds of water by 2 degrees with 245=90 BTU. And you can heat it by 18 degrees with 4518 BTU.
How do I calculate BTU?
The British Thermal Unit (BTU) is the amount of energy needed to heat a single pound of water by 1°F. 1 BTU is equivalent to 1055 joules.

How do you calculate BTUs of water?
The simple formula for water is System Delivered BTU = 500 x GPM x System Water Temperature Change.
How hot is a BTU?
The British thermal unit (BTU or Btu) is a unit of heat; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units.
