What is the minimum oil pump pressure required?

The minimum oil pump pressure required is 100 PSI. This pressure is essential to ensure that the oil is adequately delivered to the heating system, providing efficient combustion and consistent operation. At this pressure, sufficient force is generated to overcome any resistance in the lines, filters, and burner nozzles, which is crucial for optimal performance. Maintaining this level of pressure contributes to proper fuel atomization, improving the heating efficiency and reducing the risk of incomplete combustion, which can lead to safety hazards and increased emissions. Understanding the necessity of this pressure not only aids in compliance with safety regulations but also supports the effective maintenance of heating systems.
