Heating oil, also known as fuel oil, is a petroleum-based product used for heating purposes in homes, commercial buildings, and municipal facilities. It is composed of hydrocarbons derived from crude oil, specifically those in the 14- to 20-carbon atom range. During the oil refining process, these hydrocarbons condense between 250 and 350 °C, resulting in a liquid fuel with distinct properties.
Key Facts
- Composition: Heating oil consists of petroleum-derived hydrocarbons in the 14- to 20-carbon atom range that condense between 250 and 350 °C during oil refining.
- Similarity to diesel fuel: Heating oil is chemically similar to diesel fuel used for motor vehicles, but it may have different sulfur content regulations.
- Blended heating oil: Some heating oil suppliers offer blends of petroleum distillate and biofuels, typically with a 5% biofuel content.
- Usage: Heating oil is commonly used for home heating in furnaces or boilers, as well as in commercial and municipal buildings.
- Storage: Heating oil is often stored in above-ground storage tanks (ASTs) located in basements, garages, or outside adjacent to the building. It can also be stored in underground storage tanks (USTs).
- Environmental concerns: Leaks from heating oil tanks and piping can be an environmental concern, and regulations are in place to ensure proper transportation, storage, and burning of heating oil.
- Heating oil in the United States: Heating oil is widely used in the northeastern states of New York and Pennsylvania, as well as in New England, accounting for 85% of total U.S. residential heating oil use.
- Heating oil imports: U.S. refineries supply most of the domestic heating oil demand, but imports supplement the supply during winter, particularly in the Northeast region.
Chemically, heating oil is similar to diesel fuel used in motor vehicles. However, regulations governing the sulfur content of these fuels may differ. Heating oil typically has a higher sulfur content than diesel fuel, although in the United States, most heating oil is now “ultra-low sulfur heating oil” (ULSHO), meeting the same low sulfur standards as diesel fuel.
Blended Heating Oil and Usage
Some heating oil suppliers offer blended heating oil, which combines petroleum distillate with biofuels. These blends typically contain 5% biofuel content, providing a cleaner-burning and lower-carbon alternative to traditional heating oil.
Heating oil is primarily used for home heating in furnaces or boilers. It is also utilized in commercial and municipal buildings for space and water heating purposes.
Storage and Environmental Considerations
Heating oil is commonly stored in above-ground storage tanks (ASTs) located in basements, garages, or outside adjacent to the building. Underground storage tanks (USTs) can also be used, but they are less common due to their higher installation and maintenance costs.
Leaks from heating oil tanks and piping pose environmental concerns, as they can contaminate soil and groundwater. Various federal and state regulations are in place to ensure the proper transportation, storage, and burning of heating oil, classifying it as a hazardous material (HazMat).
Heating Oil in the United States
Heating oil is widely used in the northeastern states of New York and Pennsylvania, as well as in New England. These regions account for approximately 85% of total U.S. residential heating oil consumption.
U.S. refineries supply most of the domestic heating oil demand. However, during the winter season, imports supplement the supply to meet the increased demand, particularly in the Northeast region.
Conclusion
Heating oil plays a significant role in providing warmth and comfort in homes and buildings, especially in regions with colder climates. Its composition, usage, storage, and environmental considerations are important factors to consider for safe and efficient heating operations.
