Fuelling Sustainability: The Benefits of Using HVO in Your Rayburn Cooker

Posted on May 10, 2023 in Brands

Rayburn cookers have been a popular choice for many UK households for over 70 years. Their reputation for versatility, energy efficiency and durability has made them a household name. While Rayburn cookers are traditionally fuelled by oil, gas or solid fuels, there's a new, sustainable fuel in town: HVO (Hydrotreated Vegetable Oil). In this article, we'll explore the advantages of HVO in Rayburn cookers and what to consider before making the switch. If you're looking for a more sustainable and cost-effective way to power your Rayburn cooker, then keep reading!

What is HVO?

HVO is a renewable fuel made from vegetable oils that has been treated with hydrogen to remove impurities to produce a cleaner-burning fuel. HVO is a great sustainable alternative to fossil fuels and can be used in a variety of applications, including in Rayburns.

Rayburn central heating models offer the ultimate flexibility and controllability for all your heating and cooking needs. Cast-iron cooking and heating all wrapped in one stylish range. These models are available with a wide range of boiler sizes powered by HVO (95% Hydrotreated Vegetable Oil), natural gas or LPG. Whatever your requirement, Rayburn provides a highly efficient and truly versatile solution for your home.

Benefits of HVO

One of the benefits of using HVO is that it produces fewer emissions than traditional fossil fuels. HVO is a low-carbon fuel that can help reduce greenhouse gas emissions and air pollution. This makes it an ideal choice for people who are concerned about the environmental impact of their cooking.

Another advantage is that it can help reduce running costs. HVO is a cheaper alternative to traditional fossil fuels and can help reduce energy bills over time. Additionally, because HVO is a renewable fuel, it is not subject to the same price fluctuations as fossil fuels, making it a more stable and predictable fuel source.

In addition to the environmental and cost benefits, using HVO in Rayburn ranges can also improve the performance of the stove. HVO has a higher cetane rating than diesel or heating oil, which means it burns more cleanly and efficiently. This can lead to better heating and cooking performance, as well as a longer lifespan for the stove.

Converting to HVO

To convert a Rayburn range to run on HVO, the first step is to consult with a professional installer. They can assess the range and determine if any modifications are necessary to accommodate the new fuel. Once the modifications are made, the range can be fuelled with HVO just like it would with oil, gas, or solid fuels.

Please note that not all Rayburn cookers are suitable for conversion to run on HVO. Some older models may not be compatible with the fuel, so it's important to consult with a professional installer before making any modifications.


HVO can have a lower energy density than traditional fossil fuels, which means that more fuel may be needed to achieve the same heating output. However, this can be mitigated by making sure that the Rayburn cooker is properly adjusted to run on HVO, and by using a high-quality, consistent source of HVO.

Another potential drawback is that HVO has a higher pour point (the temperature at which the fuel becomes too viscous to flow) than traditional heating oil. This means that in colder temperatures, the HVO may become too thick to flow through the fuel lines and into the burner. However, this issue can be addressed by using a winter blend of HVO that has a lower pour point.

Overall, while there are some considerations and potential drawbacks to using HVO in Rayburn cookers, many users find that the benefits of this renewable, sustainable fuel outweigh any potential drawbacks. As always, it's important to consult with a professional before making any modifications to your Rayburn cooker or fuel system.


In conclusion, HVO is a renewable fuel that offers many benefits for people who use Rayburn ranges. It is a sustainable alternative to traditional fossil fuels that can help reduce emissions and lower running costs. Converting a Rayburn range to run on HVO is a great way to reduce your carbon footprint and enjoy a more sustainable and efficient cooking experience.
