How many BTU's are approximately contained in one gallon of #2 fuel oil?

One gallon of #2 fuel oil typically contains approximately 140,000 BTUs. This measurement is crucial in the heating industry as it helps professionals estimate heating requirements and make calculations regarding fuel consumption and efficiency. Understanding the energy content of fuel oil allows technicians to determine how much oil is needed to achieve desired heating levels for residential or commercial spaces.

While the actual energy content can vary slightly based on the specific formulation and additives in the fuel, 140,000 BTUs is a reliable figure widely acknowledged in the oil heating industry. This understanding helps ensure that systems are properly sized and that efficiency ratings can be effectively calculated, leading to better service and operational efficiency.
