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

No. 2 heating oil is the most commonly used type for residential heating. It is a distillate fuel similar in composition to diesel fuel and is used in oil-fired furnaces and boilers. It burns cleanly, is relatively efficient, and is widely available in North America and Europe. Because of its widespread use, No. 2 heating oil is often simply referred to as home heating oil.

No. 2 oil must meet specific standards for sulfur content and combustion quality. In many regions, ultra-low sulfur heating oil (ULSHO), which contains 15 parts per million (ppm) of sulfur or less, has become the standard. ULSHO offers environmental benefits, reducing sulfur dioxide emissions and promoting cleaner indoor air.

2. No. 1 Heating Oil (Kerosene)

Kerosene, or No. 1 heating oil, is a lighter and more refined product than No. 2 oil. It has a lower gel point, making it suitable for use in outdoor storage tanks during extremely cold weather. Kerosene burns cleaner than No. 2 oil and produces fewer pollutants, though it is usually more expensive.

Due to its lower viscosity and cleaner burn, kerosene is often used in mobile homes, modular housing, and some space heaters. It is also suitable for use in locations where venting is difficult.

3. Biodiesel Blends (Bioheat Fuel)

Biodiesel blends, commonly marketed under the name Bioheat, are a newer, renewable option made by blending traditional heating oil with biodieselfuel derived from vegetable oils, animal fats, or recycled cooking oils. Bioheat blends range from B5 (5% biodiesel) to B20 (20% biodiesel) or higher.

Bioheat offers significant environmental advantages by reducing greenhouse gas emissions and reliance on fossil fuels. It is compatible with most existing oil-fired heating systems with little or no modification, making it a convenient and eco-friendly alternative.

4. Diesel Fuel as a Substitute

In emergencies, diesel fuel can be used as a substitute for heating oil. Since No. 2 heating oil and diesel are very similar, diesel is often used when homeowners run out of heating oil and need a temporary replacement. However, this should only be a short-term solution due to cost differences and potential tax issues.

Conclusion

Heating oil comes in several forms, each suited to different needs, climates, and environmental goals. No. 2 heating oil remains the most common for residential use, while No. 1 oil and biodiesel blends offer alternatives with specific benefits. As energy efficiency and sustainability become more important, cleaner-burning and renewable options like Bioheat are expected to play a growing role in the future of home heating. Choosing the right type of heating oil ensures comfort, efficiency, and responsible energy use throughout the colder months.

What is HVO Fuel?

HVO fuel is a type of renewable diesel produced through a process called hydrotreatment. In this process, natural oils and fats are treated with hydrogen under high pressure and temperature to remove oxygen and impurities, resulting in a clean, paraffinic hydrocarbon fuel. Unlike conventional biodiesel (FAME), which contains oxygen, HVO fuel closely resembles fossil diesel chemically, offering improved stability and combustion characteristics.

Because of its chemical makeup, HVO fuel meets the EN 15940 standard for paraffinic diesel, ensuring consistent quality and suitability for use in any diesel engine without modifications.

Environmental Benefits of HVO Fuel

One of the key advantages of HVO fuel lies in its ability to significantly reduce greenhouse gas emissions. Depending on the feedstock, HVO can reduce lifecycle CO? emissions by up to 90% compared to traditional diesel. It also produces lower levels of harmful pollutants such as nitrogen oxides (NOx), particulate matter, and carbon monoxide, contributing to improved air quality and reduced health risks, particularly in urban areas.

Moreover, HVO fuel supports the circular economy by utilizing waste materials like used cooking oil and animal fats, which might otherwise be discarded. This reduces dependence on virgin crops and helps mitigate land-use concerns associated with first-generation biofuels.

Engine Compatibility and Performance

A major benefit of HVO fuel is its drop-in capability. It can be used pure (100% HVO) or blended with conventional diesel in any proportion, making it simple for industries and transport fleets to switch without modifying engines or fuel systems.

In terms of performance, HVO fuel boasts a high cetane number, which enhances combustion efficiency and engine responsiveness. Its excellent cold-flow properties mean it performs well in low temperatures, unlike some biodiesel blends that can gel or thicken. Additionally, HVO fuel tends to produce less engine deposit build-up, potentially reducing maintenance costs and extending engine life.
