1. No. 2 Heating Oil (Home Heating Oil)

No. 2 heating oil is the most commonly used fuel in residential heating systems. It is similar in composition to diesel fuel and is known for its high energy content, making it an efficient choice for heating homes. Typically delivered by truck and stored in a tank on the property, No. 2 oil is refined from crude oil and has a red dye added to distinguish it from untaxed diesel fuel used in vehicles. It burns cleanly and provides consistent heat output, making it the preferred choice in many areas.

2. No. 1 Heating Oil (Kerosene)

No. 1 heating oil, commonly referred to as kerosene, is a lighter and more refined type of fuel than No. 2 oil. Its lower viscosity allows it to flow more easily at low temperatures, making it suitable for outdoor tanks or in areas where freezing temperatures are common. Kerosene burns cleaner and produces less carbon buildup, which can reduce maintenance needs in heating systems. It is often used in portable heaters and in homes with less sophisticated heating systems.

3. Bioheat (Biodiesel Blends)

Bioheat is an eco-friendly alternative to traditional heating oils, made by blending standard heating oil (usually No. 2) with biodiesela renewable fuel derived from vegetable oils, animal fats, or recycled cooking grease. The blends can range from 2% to 20% biodiesel (B2 to B20). Bioheat reduces greenhouse gas emissions and promotes cleaner burning, which can extend the life of heating equipment. Its compatible with most existing oil-burning furnaces and is growing in popularity due to its environmental benefits.

4. No. 4 and No. 6 Heating Oils

These heavier oils are typically not used in residential settings. No. 4 oil is a blend of No. 2 and No. 6 oil and is used in some commercial or industrial applications. No. 6 oil, also known as bunker fuel, is extremely thick and requires heating before use. It is generally used in large industrial boilers and ships. These oils are less refined, more polluting, and are being phased out in many regions due to environmental regulations.

Choosing the Right Type

When selecting a type of heating oil, consider factors such as local climate, storage needs, environmental impact, and furnace compatibility. No. 2 heating oil remains the standard for most homes, but Bioheat offers a sustainable option with lower emissions. Kerosene may be necessary in colder climates where freezing is a concern.

Understanding the differences between these heating oil types helps homeowners and businesses choose the best fuel for their needs, improving energy efficiency, reducing maintenance costs, and supporting cleaner energy practices.

What is HVO Fuel?

HVO is classified as a second-generation biofuel, produced by hydrotreating vegetable oils or animal fats to remove oxygen and impurities. This process results in a paraffinic hydrocarbon fuel that closely resembles fossil diesel in its chemical composition, offering excellent combustion properties. Unlike conventional biodiesel (FAME), HVO is free of sulphur, oxygen, and aromatics, which means it burns cleaner, has a longer shelf life, and performs better in cold weather.

One of the most significant advantages of HVO is its drop-in nature it can be used as a direct replacement for diesel in existing engines and fuel infrastructure, requiring no modifications. This feature makes it highly attractive to sectors such as transportation, construction, agriculture, and logistics, where engine compatibility and fuel reliability are critical.

No. 2 Heating Oil: The Residential Standard

No. 2 heating oil is the most widely used fuel for residential heating systems. Its a distillate fuel, similar in composition to diesel, and is known for its high energy content. Most home furnaces and boilers are designed to burn No. 2 oil, making it the go-to choice for many households.

Modern No. 2 heating oil is typically ultra-low sulfur (ULSHO), containing less than 15 parts per million (ppm) of sulfur. This results in cleaner combustion, reduced emissions, and improved air quality. It is delivered to homes by truck and stored in an on-site tank, ensuring consistent availability throughout the heating season.

No. 1 Heating Oil: Light and Cold-Resistant

No. 1 heating oil is a lighter and more refined version of heating oil, closely related to kerosene. It has a lower viscosity, allowing it to flow more easily and perform better in extremely cold weather. Because of its cold-weather advantages, No. 1 oil is often used in outdoor tanks and mobile heating units.

This type of heating oil also burns cleaner than No. 2, producing fewer particulates and less soot. However, it provides slightly less heat per gallon and tends to be more expensive. No. 1 heating oil is best suited for specific applications or climates where cold resistance is a priority.

No. 4 Heating Oil: Heavy-Duty Industrial Fuel

No. 4 heating oil is a blend of distillate and residual fuel oil, making it thicker and more energy-dense than No. 1 or No. 2. It is primarily used in commercial and industrial boilers where high-volume heating is required.

Due to its higher viscosity, No. 4 oil often needs to be preheated before it can be burned efficiently. It also produces more emissions, so it is subject to stricter environmental regulations and is generally not recommended for residential use. Its cost-efficiency makes it suitable for institutions or businesses with large-scale heating demands.

Bioheat Fuel: The Sustainable Alternative

Bioheat is a renewable, environmentally friendly type of heating oil made by blending biodiesel with traditional No. 1 or No. 2 oil. Biodiesel is produced from renewable resources such as soybean oil, used cooking oil, or animal fats.

Bioheat fuel can be used in existing oil heating systems without modifications, offering a seamless way to reduce carbon emissions and dependence on fossil fuels. Common blends range from B5 (5% biodiesel) to B20 (20% biodiesel), with higher blends providing even greater environmental benefits.

Conclusion

Choosing the right fuel depends on your specific heating system, climate, and environmental priorities. Among the various types of heating oil, No. 2 is ideal for most homes, No. 1 serves colder climates or portable needs, No. 4 is reserved for industrial use, and Bioheat is a smart, green alternative. By understanding these options, you can ensure a warm, efficient, and sustainable heating solution.

What Is Red Diesel?

Red diesel is essentially the same as standard (white) diesel in terms of performance and composition, but its dyed red to signify its off-road use exemption from full fuel duties. It is illegal to use red diesel in regular road vehicles in most countries. Instead, it's intended for:

• Farm equipment (tractors, harvesters, irrigation pumps)

• Construction machinery (excavators, cranes, loaders)

• Generators and backup power systems

• Boats and marine vessels (in certain jurisdictions)

• Commercial heating systems

Because of the reduced tax, red diesel is considerably cheaper than road diesel, making it a cost-effective option for fuel-intensive operations.
