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 fast will 15 000 BTU boil water?
On a 15,000 BTU burner, with water starting at 50°F it would take 12-15 minutes for 6 quarts (1.5 gallons) of water to boil. And 20-25 minutes to bring 12 quarts (3 gallons) of waters to a boil.
How much energy does it take to boil water?
The energy required to change water from a liquid to a solid is 333.7 kJ/kg while the energy required to boil water is 2257 kJ/kg. The amount of energy needed to change the phase of water to a gas from a liquid is 540 times the amount of energy needed to raise the same amount of water 1° C.
How many BTU does it take to boil 5 gallons?
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 20 gallons?
Water that is at boiling has 180 btus in it, per lb. That means 20 gallons as accumulated about 120,000 btu.
Is 12000 Btu burn enough?
For most users, one power burner (12,000 BTUs or higher) is more than adequate—especially when paired with two medium-strength burners and one low burner for simmering. If you do a lot of cooking that requires quick high heat, such as stir-frying or searing, you may want to push the power up.
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.
Is it cheaper to boil water with gas or electric?
Because gas is cheaper than electricity, it works out slightly cheaper to boil water on a gas hob than using an electric kettle, as long as you are boiling just the quantity you need and switch off the hob as soon as it has boiled.
How long does it take to boil off a gallon of water?
How long does it take a gallon of boiling water to evaporate? If we boil water it takes, for example, 5 minutes to reach the boiling point. If we continue heating, it will take another 20 minutes or so before the water has completely evaporated (which is good, because it gives us time to save our kettle).
How much does it cost to boil a gallon of water?
It is generally accepted that it costs about 1¢ to 2¢ to heat a gallon of water. The exact amount will depend on the efficiency of your water heater, whether you use gas or electric and exactly what your electric or gas costs are.
How many BTU 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.
What’s the meaning of BTU?
British Thermal Units (BTU) are traditional units for heat. Each propane burner differs in terms of design and efficiency. That means that the higher the BTU doesn’t always mean the better the burner. For brewing 5 to 10-gallon batches, burners with 50,000 to 100,000 BTU/Hr will all get the job done.
How many BTU do I need for a shrimp boil?
For backyard use, he recommends a 50,000 BTU burner and a regulator, a safety device that goes between the tank and the burner that will stop the flow of propane if the line ruptures. The height of the burner is important, too. It should not have a high center of gravity in case anybody bumps into it.
What are BTU units?
A British thermal unit (Btu) is a measure of the heat content of fuels or energy sources. It is the quantity of heat required to raise the temperature of one pound of liquid water by 1 degree Fahrenheit at the temperature that water has its greatest density (approximately 39 degrees Fahrenheit).
