How To Learn the Component Parts of an Oil Furnace

Houses are kept warm during winter or during cold seasons by furnaces. There are different types of furnaces found in the market, there's gas furnace, propane furnace, an electric furnace and there's also an oil furnace. Most houses or old buildings use an oil furnace to warm the place and also to provide warm water. The heat energy that fuels a furnace could be supplied by combustion, by electricity or through induction. To better understand how oil furnaces keep you warm, it is important to get to know the component parts of oil furnaces. 

The furnace can be divided into three major components and each component has it function. Here is information about how to identify the three major components of an oil furnace and its parts and functions:

1. Combustion

  • Burners - This is where the flame originates from.
  • Heat exchanger - This is the device used for heat transfer from one medium to another.
  • Draft inducer - This is a special fan which is installed in the vent used to vent a furnace.
  • Venting or ventilator - This is where the by products or waste of the combustion in your furnace is exhaled or exhausted. This is also where the release of useful heat passes through for the distribution in your households.

2. Power or control and safety device

  • Controls - The control and safety device of a furnace includes the following parts: ignition control, gas valve, ignitor, transformer, flame sensor, blower control board, limit control, and flame roll out switch.
  • Transformer - It provides twenty four volts of electricity to the power controls. These volts are applied to the thermostat that can be found in the living space.

Each part plays a very important role in how furnaces are controlled and how it safely distributes heat into households. The safety controls act to prevent burner operations whenever other devices in the furnace malfunction. 

3. Blower and air movement

  • Blower - This is the part of the furnace that works hardest and frequently needs repair. The blower also is the part that draws air in which is warmed and the air that will be distributed back into the space that needs heating.

Although oil furnace repairs could be limited to some parts of the furnace like the filters, the blower, the motor belts, the switches and the thermostat, etc., learning about the basic parts of furnaces would greatly help you in troubleshooting and making minor repairs to problems with your furnaces. If trouble continues to persist it is strongly suggested that you hire a professional to take care and repair the furnace. Prices for repair may vary depending on what component or part needs to be repaired.

When all parts of the oil furnace works without a hitch, your household would be provided the heat and the hot water you need to keep warm during cold and winter seasons.
