Approximately how many BTUs are contained in 1 gallon of #2 oil?

1. 120,000 BTUs

2. 140,000 BTUs

3. 160,000 BTUs

4. 180,000 BTUs

The correct answer is: 140,000 BTUs

The correct answer is that 1 gallon of #2 oil contains approximately 140,000 BTUs. This value is significant in the context of heating and energy calculations, as it helps professionals determine the efficiency and energy output of oil heating systems. Understanding the energy content of #2 oil is essential for calculating how much fuel is needed for a certain heating demand. For instance, if a heating system requires a specific amount of BTUs to maintain a comfortable temperature, knowing that each gallon of #2 oil provides around 140,000 BTUs allows technicians to estimate fuel usage accurately. This information is also crucial when comparing different heating fuels, as it influences decisions on fuel type and system design based on efficiency, cost, and performance. Being familiar with these values contributes to better energy management and optimization in residential and commercial heating applications.
