Types of Heating Oil in the UK: A Comprehensive Guide
Heating oil remains a vital energy source for many households and businesses in the UK, especially in rural areas where natural gas supply is limited. Understanding the different types of heating oil available can help consumers make informed decisions about efficiency, cost, and environmental impact. This article explores the main types of heating oil used across the UK.
What is Heating Oil?
Heating oil is a liquid petroleum product used primarily to heat buildings via oil-fired boilers or furnaces. Its stored in tanks and burned to generate heat, making it a popular choice in places off the gas grid. In the UK, heating oil plays an essential role in maintaining warmth during colder months.
Main Types of Heating Oil in the UK
There are primarily two types of heating oil widely used in the UK: Kerosene (also known as 28-second oil) and Gas Oil (also referred to as red diesel or 35-second oil). Each type has distinct characteristics suited to different applications.
1. Kerosene (28-Second Oil)
Kerosene is the most common type of heating oil used by UK households. It is a refined petroleum product that is relatively clean-burning compared to other oils. Kerosene is sometimes called 28-second oil due to its viscositymeasured by the time it takes to flow through a specific size nozzle at 20C (28 seconds).
-
Usage: It is mainly used in domestic heating systems, particularly in oil-fired boilers for homes.
-
Advantages: Kerosene burns cleanly, producing fewer emissions compared to heavier oils, and it offers high energy content, providing efficient heating.
-
Cost: Generally, kerosene is more expensive than red diesel due to taxes but is preferred because it is suitable for residential use and approved for domestic boilers.
-
Environmental impact: It emits carbon dioxide like all fossil fuels but less soot and particulates, making it slightly better for indoor air quality.
2. Gas Oil (Red Diesel or 35-Second Oil)
Gas oil, also known as red diesel, is a heavier and less refined form of heating oil. It is dyed red in the UK to distinguish it from regular diesel fuel for vehicles because it benefits from a lower tax rate.
-
Usage: It is primarily used for commercial heating, agricultural machinery, and industrial boilers. While it can be used for heating, red diesel is not permitted for domestic heating in many cases due to tax regulations.
-
Advantages: Gas oil is typically cheaper than kerosene because of the reduced tax. It has a slightly higher viscosity (hence 35-second oil) and may require different burner settings.
-
Cost: Lower than kerosene due to tax exemptions on specific uses, but legal restrictions apply on its domestic use.
-
Environmental impact: It tends to produce more soot and particulate matter than kerosene, which can affect boiler maintenance and emissions.
Emerging Alternatives and Trends
As the UK moves toward greener energy, alternatives to traditional heating oil are gaining attention. Bioheating oil, made from renewable sources such as vegetable oils and animal fats, is increasingly mixed with conventional heating oil to reduce carbon emissions. These blends can be used in existing oil boilers with little or no modification.
Furthermore, there is a growing push towards heat pumps and electric heating systems, which, combined with renewable electricity sources, offer cleaner alternatives to fossil fuel heating.
Conclusion
Understanding the types of heating oil available in the UK is essential for consumers seeking efficient, cost-effective, and environmentally conscious heating solutions. While kerosene remains the go-to for domestic heating, gas oil serves industrial and agricultural purposes. As the energy landscape evolves, greener alternatives like biofuels and electric heating are becoming more accessible, promising a warmer, cleaner future for UK homes and businesses.
