## How many BTU does it take to convert water to ice?

It might also be termed the latent heat of melting, or the latent heat of freezing. When one pound of ice melts, it absorbs 144 BTU’s at a constant temperature of 32° F., and if one pound of water is to be frozen into ice, 144 BTU’s must be removed from the water at a constant temperature of 32° F.

## How many BTUs does it take to melt a pound of ice?

One pound of ice requires 144 Btus to melt. The amount to melt one ton of ice is 288,000 Btu’s (144 x 2,000). Dividing that over 24 hours, one ton of refrigeration equals 12,000 Btu/hr (288,000 / 24).

**How hot is a BTU?**

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).

### How many BTU does it take to raise 1 gallon of water 1 degree?

A British Thermal Unit (BTU) is a measurement of heat energy. 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 will 1 gallon of water absorb?

The answer then is 1 gallon of water will absorb 1,251 BTUs going from ambient temperature (assumed to be 62o F) to 212o F.

**How many Btus are in a 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. 1 Ton = 25 Million (app.)

#### How many BTU does it take to change water to vapor?

LATENT HEAT OF VAPORIZATION For water in an open pan, it is 970 Btu per pound, so 20 pounds of water at 212° requires 20 × 970 or 19,400 Btu to turn it into steam or water vapor, also at 212°F.

#### How many BTU do I need to heat a 12×12 room?

How many btu do I need to heat 3,000 square feet?

Room/Area Size | Heating Capacity(BTU) |
---|---|

100 sq ft | 4,000-6,000 BTU |

200 sq ft | 9,000-11,000 BTU |

300 sq ft | 12,000-16,000 BTU |

400 sq ft | 18,000-22,000 BTU |

**What is a good BTU for water heater?**

A common input is 34,000 BTUs on a 40-gallon tank and 36,000 BTUs on a 50-gallon tank. The higher the BTU input and efficiency, the faster the recovery. Electric water heaters typically have one 5,500-watt or two 4,500-watt elements. Two lower-kilowatt elements will heat much faster than one higher-wattage element.

## How do you calculate BTU for a room?

Step 1: Measure The Square Footage (Length, Width, Height Exact To 0.25 Ft)

- Square Footage = Measured Length x Measured Width.
- Square Footage = 16 3/4 ft (Length) x 14 1/2 ft (Width) = 243 sq ft.
- BTU Requirement = 500 sq ft x 20 BTU per sq ft = 10,000 BTU.
- Accurate BTU Calculation = 20,000 BTU * 1.1 + 600 BTU = 22,600 BTU.

## How many BTU does it take 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 BTU do I need for 150 square feet?**

6,000 BTUs

150 – 250 sq. feet: 6,000 BTUs.

### How many BTU is 144 square feet?

How many btu do I need for my room?

Room Type | Room Size | Recommended BTU |
---|---|---|

10 x 10 room | 100 sq ft | 5,000 BTU |

12 x 12 room | 144 sq ft | 5,000 BTU |

12 x 24 room | 576 sq ft | 12,000 BTU |

13 x 13 room | 169 sq ft | 6,000 BTU |

### How many BTU is a 60 gallon water heater?

Cyclone 60 Gallon 120,000 BTU Natural Gas Commercial Water Heater.

**What is the significance of BTU in water heater?**

The BTU rating on a water heater indicates the number of pounds of water that that water heater can heated by 1 °F in 1 hour. For instance, the left panel in the image above is from a 40-gallon gas water heater rated 34,000 BTUs. This means that this water heater will heat 34,000 lbs.
