The Fundamentals Of Fuel Oil Furnace Schematic Diagrams



In order to fully understand how fuel oil furnaces work, it’s important to gain an understanding of the fuel oil furnace schematic diagrams. These diagrams provide a way for technicians and homeowners to troubleshoot and repair their own systems, allowing them to save money and time. Understanding how to read these diagrams is essential for anyone wanting to install, use or maintain a fuel oil furnace.



With an understanding of these diagrams, you will be able to quickly identify any potential issues with the fuel oil furnace, as well as quickly determine if the system has been set up properly. This will save you time and money, and ultimately give you peace of mind knowing that your furnace is running as efficiently as possible.



Components of a Fuel Oil Furnace



Fuel oil furnaces are highly efficient and typically use natural gas, propane, or fuel oil as an energy source. The components of the furnace consist of a combustion chamber, a heat exchanger, a power-vent fan, an evaporator coil, an expansion tank, a flue, and a vented chimney. Each of these components are connected in such a way that the fuel oil is heated within these chambers, which then heats the air to create hot air for your home.



The Heat Exchanger



The heat exchanger is a large metal plate located in the middle of the furnace. This plate transfers the heat from the burning fuel oil to the air in the chamber before it’s released into your home. The heat exchanger contains multiple small tubes that help circulate the hot air, and can be found in either steel or cast iron.



The Power-Vented Fan



The power-vented fan helps bring cool fresh air into the furnace, and exhausts the hot air from the combustion chamber. This fan is located at the back of the furnace, and is usually powered by an electric motor or a battery. It works to pull the hot air out of the furnace and then pushes it back into the home through the vents.



The Expansion Tank



The expansion tank is used to store excess pressure that builds up in the furnace due to the heat produced by the furnace. It reduces the pressure, allowing the furnace to run more safely and efficiently. This tank should be checked regularly to ensure it is in working condition and the proper levels of pressure are being maintained.



The Flue



The flue is the metal tube that runs from the top of the furnace to the outside wall of your home. This tube allows the hot air from the furnace to escape safely from your home. It is important to ensure that the flue is clear to allow for proper airflow and reduce the chances of carbon monoxide buildup.



Fuel Oil Furnace Schematic Diagrams



Fuel oil furnace schematic diagrams are invaluable tools for anyone wanting to understand how their furnace works. These diagrams provide a visual representation of all of the components in the furnace and how they connect to one another. With just a simple glance, it’s easy to spot any potential problems or areas of concern. Furthermore, these diagrams will also help you to identify parts and components in the event of a breakdown, enabling you to find the right part quickly and easily.
