What Does it Mean to Bleed a Furnace?


You may or may not have heard the term before, but either way it’s a term that all heating oil dealers are familiar with. Bleeding a furnace is done in order to remove air from the fuel lines in the event that the furnace runs out of oil to burn. While this important maintenance task is best done by a professional, understanding why it’s important will help you determine when you need to call Fsi Oil and Propane.


Why is Bleeding a Furnace Necessary?


When a tank runs out of oil or any other heating fuel, the equipment will continue to try and draw fuel in. Instead, air is pulled into the fuel lines. The process of bleeding will remove the air from the lines and keep the heating system working optimally.


How does Bleeding the Furnace Work?


Bleeding a furnace is a lot like changing the oil of your car. It’s a time-consuming process, but it’s necessary! When a Fsi Oil and Propane technician comes to your home, he or she will first cut off the power to the furnace and open the bleeder valve to let air out of the unit. Once the air is cleared, additional cleaning or refilling of the furnace may be necessary before it’s turned on again.


Often times when the bleeding process is finished, and it may take more than one cycle to complete the process, you’ll find your furnace operates more quietly and efficiently – consuming less fuel and burning the fuel more cleanly. It’s important to call and schedule a bleeding if you ever run out of fuel or if your heating system seems a big more sluggish than usual. Call Fsi Oil and Propane today to learn more!
