## How many BTUs do you need to boil water?

A BTU (British Thermal Unit) describes the amount of energy to raise 1 lb of water 1 degree Fahrenheit in one hour. Water equals 8.3 lbs per gallon. To boil one gallon of water starting 70°F in 1 hour you will need 8.3 x (212-70) = **1,178.6 BTUs**.

## 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 do I calculate BTU?

For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: **(desired temperature change) x (cubic feet of space) x .** **133 = BTUs needed per hour**.

## How many BTUs does it take to raise air 1 degree?

It takes **0.24 BTU** of heat to change the temperature of one pound of air by one degree F.

## Does higher BTU use more gas?

The higher the BTU capacity of a gas burner, **the hotter the burner can get**; the hotter the burner, typically the faster the cooking times. But while BTU measures heat production, it doesn’t necessarily translate into better cooking performance. … Some ranges “cycle” heat for low-temperature cooking.

## How many BTUs do I need to heat a room calculator?

Chart of Recommended Heating BTU Per Square Foot

Room/Area Size: | Examples: | Ave. Recommended BTU: |
---|---|---|

100-200 sq ft | Small den or office | 4,000-8,000 BTU |

200-300 sq ft | Den, office, small bedroom | 7,000-15,000 BTU |

300-400 sq ft | Efficiency apartment | 12,000-18,000 BTU |

400-500 sq ft | Studio/1-bedroom apartment, Tiny house | 15,000-24,000 BTU |

## How do you calculate boiling time?

Using the formula **Pt = (4.2 × L × T ) ÷ 3600** you can calculate the time it takes to heat a specific quantity of water from one temperature to another temperature.

## How do you calculate BTUs of water?

**BTU = Flow Rate In GPM (of water) x (Temperature Leaving Process – Temperature Entering Process) x 500.4***Formula changes with fluids others than straight water.

## 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.
