Keep reading to learn more about these gases and ensure your next BBQ is a hit.

Butane and Propane Gas

Are you wondering, what are the pros and cons of gas BBQ? The answer lies in understanding the difference between propane and butane. While both are commonly used for barbecues, they have distinct characteristics that make them suitable for different situations.

Basic Descriptions and Properties

Propane is a highly flammable hydrocarbon gas used widely for heating and cooking. It's known for its low boiling point of -42°C, making it suitable for colder climates.

Propane is often stored in green canisters and referred to as patio gas. Butane, also a flammable hydrocarbon, has a higher boiling point at -2°C, making it ideal for warmer weather. It is commonly found in blue canisters and is used in portable cooking appliances.

Propane cylinder sizes range from 3.9kg to 47kg, while butane cylinders are typically smaller, ranging from 4.5kg to 15kg.

Common Uses of Each Gas Type in the UK

Propane is favoured for larger BBQs with three or more burners, as it performs well in various weather conditions and is effective throughout the year. It's commonly used in standard garden and larger event BBQs.

Butane, being more efficient in warm weather, is better suited for smaller, portable BBQs and tabletop grills used for casual cooking. It's a popular choice for camping and single-burner applications, where simplicity and portability are essential.

Comparison of Propane and Butane

Propane Characteristics

Propane is widely favoured by BBQ enthusiasts across the UK, commonly housed in green canisters and referred to as patio gas. This gas is particularly suitable for medium-sized gas BBQs, where a 5kg gas bottle can provide enough fuel for approximately ten robust BBQ sessions.

For larger setups involving BBQs with five or more burners, larger quantities such as a 10kg or even a 13kg bottle may be required. These larger canisters ensure sufficient gas for prolonged cooking periods or when hosting sizable groups, making it a reliable choice for serious grillers.

Butane Characteristics

Butane is typically found in blue canisters and is the preferred choice for smaller, more portable BBQs that utilise camping gas. It performs exceptionally well in warmer weather conditions but might not be as effective when the temperature drops.

The compact and lightweight nature of butane canisters makes them ideal for easy transportation, fitting perfectly with casual, spontaneous BBQ outings and smaller family events where simplicity and mobility are valued.

Key Differences Between Propane and Butane

Boiling Points and Their Implications

Propane, with a boiling temperature of -42°C, can vaporise even under extremely cold conditions, making it highly suitable for consistent use throughout the year, regardless of temperature.

Butane, which has a boiling point of -2°C, tends to be less effective in colder weather because it does not vaporise as readily, leading to reduced efficiency when the temperature drops.

Pressure Differences and Relevance to Outdoor Storage

Propane exerts a higher pressure than butane at the same temperature, enhancing its suitability for outdoor storage and utility in diverse weather conditions.

This characteristic ensures that propane can maintain its effectiveness and safety as an outdoor fuel source, even when temperatures are volatile or particularly low.

Efficiency Comparisons in Varied Weather Conditions

Butane is notably more energy-efficient in warmer weather, making it an excellent choice for summer barbecuing. In contrast, its efficiency significantly decreases in colder weather.

Propane, conversely, maintains a high level of efficiency across a broad spectrum of temperatures, which supports reliable and flexible usage for grilling throughout the year.

Appearance and Packaging Differences

Butane is commonly stored in blue canisters, which are easily distinguishable from the red or green canisters used for propane. Green canisters are often specifically labelled as patio gas, a popular choice for BBQ enthusiasts.

This colour-coded system not only aids in quick identification but also promotes safety and appropriate handling of the different types of gases used for various heating and cooking needs.

What Is The Best Gas For BBQ UK?

In the UK, choosing the right gas for your BBQ largely depends on your specific BBQ model and weather conditions.

Propane is typically the preferred choice for many gas BBQs, especially useful for those planning to grill during the colder months because it performs reliably throughout the year. For smaller, portable BBQs often used in warmer weather, butane could be a more cost-effective option.

It’s important to refer to your BBQ’s manual to confirm the appropriate type of gas to use, ensuring your grilling experience is both safe and effective (1).

Frequently Asked Questions

What Are the Cons of Gas BBQ?

While convenient, gas BBQs can be more expensive initially than charcoal models due to the cost of the unit and the gas. They also may not provide the same smoky flavour that charcoal BBQ enthusiasts favour.

Additionally, gas BBQs require a steady supply of propane or butane, which means planning for gas refills and ensuring proper storage of spare gas canisters.

Is Gas or Propane BBQ Better for Both Indoor and Outdoor Use?

Propane gas BBQs are generally recommended for outdoor use only due to safety concerns with carbon monoxide buildup, which can be hazardous indoors. Indoor BBQ options typically utilise electric grills because they don’t produce carbon monoxide.

Propane is a popular choice for outdoor cooking due to its efficiency in various weather conditions and wide availability. If you need gas for indoor portable heaters, butane is a popular choice as it performs well in warmer temperatures and is relatively easy to handle.

Can I Interchange Regulators Between Propane and Butane Gas Bottles?

It is not advisable to interchange regulators between propane and butane canisters due to differences in pressure and fittings. Each type of gas requires a specific regulator that matches the pressure requirements and connector type of the gas canister.

Using the wrong regulator can lead to gas leaks and pose serious safety risks.

Can I Use Liquefied Petroleum Gas in My BBQ?

Yes, you can use liquefied petroleum gas (LPG) in your BBQ, including propane and butane gases. These types of gas are commonly used for BBQs due to their high energy output and clean burning properties.

How Do I Know How Much Gas Is Left in My BBQ Gas Cylinder?

You can use the water method to determine how much gas is left in your BBQ gas cylinder. Gently pour warm water down the side of the canister and then feel for a temperature change with your hand.

The part of the canister that remains cool to the touch indicates the remaining gas level, as the liquid gas inside absorbs heat. This simple technique helps you gauge how much gas you have left to ensure you're well-prepared for your next BBQ session.

Conclusion

In conclusion, choosing the right gas for your BBQ involves understanding the characteristics and applications of propane and butane. Propane is ideal for consistent and versatile outdoor grilling across various temperatures, making it suitable for year-round use in the UK.

Butane, while cost-effective for casual and portable grilling in warmer conditions, has its limitations in colder weather. Always consult your BBQ’s manual to select the correct gas type, ensuring safety and efficiency in your grilling adventures.

Whether you opt for propane or butane, proper maintenance and adherence to safety guidelines are essential for a successful BBQ experience.
