What is the heat content of a gallon of No. 2 fuel oil?

The heat content of No. 2 fuel oil is approximately 140,000 BTUs per gallon. This measurement is critical for HVAC professionals as it helps in calculating fuel needs for heating systems and ensuring efficient operation of oil burners. Understanding the heat content allows for proper sizing of equipment and predicting energy costs based on fuel consumption during heating cycles.

Options that present values lower or higher than 140,000 BTUs do not typically align with accepted industry standards. For practical purposes, knowing that No. 2 fuel oil offers a reliable energy output of around 140,000 BTUs assists technicians in providing accurate estimates and ensures that installations and maintenance practices are effective and efficient.
