What is the ideal net stack temperature range for oil furnaces?

The ideal net stack temperature range for oil furnaces is typically between 400 to 500 °F. This temperature range is crucial for ensuring optimal combustion efficiency and proper functioning of the furnace. When the stack temperature falls within this range, it indicates that the oil is being efficiently burned and the heat exchange process is functioning effectively. It helps in minimizing the formation of soot and reduces the potential for fuel condensation, which can lead to flue gas condensation issues. Maintaining the stack temperature in this range also contributes to optimal system performance and longevity. As a result, the selection of this specific temperature range reflects the operational standards established for oil-fired heating systems, ensuring they operate efficiently and effectively.
