When it comes to heating your home, understanding the terminology can sometimes be confusing. Two terms that often get used interchangeably are “fuel oil” and “heating oil.” This can leave many homeowners wondering if there’s actually a difference between the two. The short answer is yes, but it’s a bit more nuanced than you might think.
Let’s clear up the confusion. We’ll explore the relationship between fuel oil and heating oil, explain what you need to know to keep your home warm and your heating system running efficiently, and help you make the best choice for your household.
Fuel oil is a broad term for any petroleum product that is burned in a furnace or boiler to generate heat or in an engine to generate power. These oils are created during the distillation of crude oil. Because “fuel oil” is a general category, it includes several different types, such as kerosene, diesel fuel, and, of course, heating oil.
These different types of fuel oil are graded by weight and viscosity. The grades range from No. 1 (the lightest) to No. 6 (the heaviest). The lighter oils, like kerosene, are more refined and burn cleaner, while the heavier oils are less refined and are typically used in large industrial settings, not for residential heating.
Heating oil is a specific type of fuel oil. It’s the product you use to warm your home if you have an oil-fired furnace or boiler. Think of it this way: all heating oil is fuel oil, but not all fuel oil is heating oil.
In the United States, the heating oil used for residential purposes is typically a blend of No. 1 and No. 2 fuel oils. This specific blend is formulated to provide clean, efficient, and reliable heat for your home. It’s chemically very similar to diesel fuel, but there’s a key difference: heating oil is dyed red to distinguish it from on-road diesel fuel, which is taxed at a higher rate. Using red-dyed heating oil in a diesel vehicle is illegal.
The quality of your heating oil directly impacts the efficiency and longevity of your furnace or boiler. Many suppliers offer low-cost oil that contains high levels of sulfur and other impurities. While the initial price might seem appealing, this cheaper fuel can lead to significant problems down the line, including increased wear on your heating equipment and higher maintenance costs.
