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 does it take to boil 1 gallon of water?
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.
Is 8000 BTU good for cooking?
So would an 8,000 BTU burner be sufficient? ... You'll want a higher BTU output to reach your boiling temperature quickly . Ranges with versatile burners can make cooking a breeze by giving you the flexibility to cook a wide range of foods on a single burner.
How much heat is required to boil the water?
Why It Matters. Phase changes in pure water occur at a specific temperature. At 1 atm, water freezes at 0° C and boils at 100° C. 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 .
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.
How long does it take 2 gallons of water to boil?
How long does it take to boil a gallon of water? If you are boiling water on a usual stove in a tank that conducts heat well, then it will take you approximately one hour to see the one gallon of water (if the water was cold when you started to simmer it).
Does higher Btu use more electricity?
BTU – British Thermal Unit – BTU is a very common term when it comes to HVAC equipment. One BTU is the amount of energy it takes to raise one pound of water one degree Fahrenheit. The higher the BTUs, the more power the system has .
How many BTUs do I need to cook?
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 10000 Btu enough for BBQ?
The industry standard for BTUs needed for a grill is between 75 and 100 BTUs per square inch of heating surface. ... Typically, a grill with between 80 to 100 BTUs per square inch of cooking surface will provide fast and consistent heat.
What happens to the water as it boils?
When water is boiled, the heat energy is transferred to the molecules of water , which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
Where did the water go after boiling?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air .
Why is heat required to boil water?
Boiling water is an endothermic process, which supplies heat to the water molecules, increasing their potential energy. The applied heat causes the water molecules to move further away from each other without causing any increase in overall temperature.
How many BTUs do I need to heat 4000 square feet?
| Home Size (Heating): Standard Climate Very Hot Climate | 3,500 square feet 157,500 BTU 105,000 BTU | 4,000 square feet 180,000 BTU 120,000 BTU | 4,500 square feet 202,500 BTU 135,000 BTU | 5,000 square feet 225,000 BTU 150,000 BTU |

How do you calculate BTU for a burner?
- Determine the energy output of the stove from the label on the back of the unit or from the manufacturer's information. ...
- Total the watts for the four heating elements. ...
- Divide by 1,000 to get the total kilowatts of output. ...
- Multiply by 3,412.12 to get the total BTUs per hour.
How many BTUs do I need to deep fry?
Single and double burners are readily available at any good outdoor outfitter. 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.
