When sizing a fuel oil system, which factor is primarily considered?

When sizing a fuel oil system, the primary factor considered is maximum capacity. This is essential because the maximum capacity determines the system's ability to meet peak demand and ensure adequate fuel supply for heating and other operational needs. A correctly sized fuel oil system must be capable of delivering enough fuel during the highest consumption periods without running out, which can lead to inefficient operation or service interruptions.

Additionally, understanding maximum capacity allows for the selection of appropriate storage tanks and delivery systems, ensuring that the entire system functions efficiently and complies with safety regulations. While other factors like volume, environmental safety, and cost efficiency are important in the overall assessment of a fuel oil system, they are secondary to ensuring that the system can handle the maximum anticipated load effectively. This ensures reliability and efficiency in fuel delivery and management for the intended application.
