Understanding the Different Types of Heating Oil
Heating oil is a widely used fuel for home heating systems, especially in regions with harsh winters. It powers furnaces and boilers, providing a reliable source of warmth during the colder months. While many people refer to heating oil types as a single product, there are actually several types, each with distinct characteristics. Knowing the differences can help homeowners choose the best option for efficiency, performance, and environmental impact.
No. 2 Heating Oil
No. 2 heating oil is the most common type used in residential heating. It is similar to diesel fuel and is known for its high energy content, making it highly efficient. This type of oil is typically delivered by truck and stored in aboveground or underground tanks. No. 2 oil burns cleanly in well-maintained systems and is compatible with most oil-fired furnaces and boilers. It is the standard fuel for home heating due to its availability and cost-effectiveness.
No. 1 Heating Oil
No. 1 heating oil is a lighter, more refined version of No. 2. It has a lower viscosity and a lower pour point, meaning it flows better in colder temperatures. This makes it a good choice for outdoor storage tanks and regions with extremely cold winters. Although it has slightly less energy content than No. 2, its resistance to gelling in low temperatures can be crucial for reliable heating. It is often used as a blend with No. 2 oil to improve winter performance.
Kerosene
Kerosene is another type of heating fuel that is more refined than both No. 1 and No. 2 oils. It is commonly used in space heaters, portable heating units, and mobile homes. Kerosene has excellent cold-weather properties and burns very cleanly, producing minimal soot and emissions. It is typically more expensive, but its clean burn and safety in ventless systems make it a valuable option for specific heating needs.
Bioheat® Fuel
Bioheat® is a modern, renewable alternative that blends traditional heating oil with biodiesel made from plant oils or recycled fats. It is available in various blends (such as B5, B10, and B20) and can be used in existing heating oil systems without modification. Bioheat® reduces greenhouse gas emissions and supports energy sustainability.
Conclusion
Understanding the different types of heating oil helps homeowners make informed decisions based on climate, system compatibility, and environmental impact. Whether choosing standard No. 2 oil or a cleaner option like Bioheat®, selecting the right fuel ensures reliable, efficient home heating.
