BTU to Heat Water Calculator

Formula

To calculate the BTUs required to heat water:

\[ BTUs = G \times \Delta T \times 8.34 \]

Where:

\(BTUs\) is the amount of energy required in British Thermal Units
\(G\) is the number of gallons of water
\(\Delta T\) is the temperature change in degrees Fahrenheit
8.34 is the number of BTUs required to raise one gallon of water by one degree Fahrenheit

What is a BTU?

A British Thermal Unit (BTU) is a unit of heat energy. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. BTUs are commonly used in the power, steam generation, heating, and air conditioning industries. Understanding BTUs is essential for calculating the energy required to heat or cool a given amount of water or air.

Example Calculation 1

Let's assume the following values:

Number of Gallons of Water (G) = 10
Temperature Change (ΔT) = 50°F

Using the formula:

\[ BTUs = 10 \times 50 \times 8.34 = 4170 \text{ BTUs} \]

The BTUs required to heat the water is 4170 BTUs.

Example Calculation 2

Let's assume the following values:

Number of Gallons of Water (G) = 20
Temperature Change (ΔT) = 30°F

Using the formula:

\[ BTUs = 20 \times 30 \times 8.34 = 5004 \text{ BTUs} \]

The BTUs required to heat the water is 5004 BTUs.
