What is the primary purpose of a fuel oil pump in the system?

The primary purpose of a fuel oil pump in a heating system is to deliver oil to the burner at the proper pressure. This functionality is crucial because maintaining the correct pressure ensures that the fuel oil can be effectively atomized and mixed with air for efficient combustion. Proper atomization is critical for achieving optimal burning conditions and for maximizing energy efficiency while minimizing emissions.

The burner relies on the fuel oil pump to provide a consistent and adequate supply of fuel at the right pressure which enables the burner to operate smoothly and reliably, promoting proper heat generation. Without this function, the burner may experience inadequate fuel supply, leading to poor combustion performance and potential equipment issues.
