We Know: All About Oil Furnaces Work
How do oil furnaces work?
Forced air oil furnaces burn oil that is stored in a tank as a fuel source. The oil flows through a pipe to a combustion chamber in which the fuel is atomized. High-voltage electrodes ignite the atomized oil. From the heat exchanger, it goes to the flue gas exhaust chamber. The heat is then directed by a forced air circulating fan. Some newer oil furnaces have a higher efficiency rating because they use a secondary heat exchanger and an auxiliary fan.
The appropriate furnace size for your house is dependant on the number of BTUs (British Thermal Units) it needs to maintain adequate warmth. Furnaces that are too small are ineffectual, while furnaces that are too large cost more and are less efficient because of constant on and off cycling.
What are the advantages to oil furnaces?
The advantage to heating with oil is that it may be available when other forms of fuel, such as natural or propane gas, are not.
What are the disadvantages to oil furnaces?
Each oil furnace is a little different, but here are some common problems:
