What Can I Use Instead of Bioethanol? Best Alternatives

Bioethanol fires are popular for their clean burn and stylish design, but they aren’t the only option. If you’re exploring alternatives due to cost, availability, or performance, this guide compares the best substitutes — from gel fuel to denatured alcohol — so you can enjoy safe, beautiful flames without compromise.

Why Look for Bioethanol Alternatives?

Bioethanol is one of the most popular fuels for modern fires, offering a clean burn, easy handling, and a stylish flame without the need for a chimney or flue. But sometimes, it isn’t the right choice.

You may want more heat output, lower ongoing costs, or simply a substitute when bioethanol isn’t readily available. Whatever the reason, knowing your options means you can keep the atmosphere of a real flame without compromise.

This guide explores the most reliable bioethanol alternatives, what makes them work, and what you need to know before making the switch.

The Leading Substitutes for Bioethanol Fuel

1. Gel Fuel

Gel fuel is often the closest substitute for bioethanol. It’s typically made from isopropyl alcohol mixed with thickening agents, giving it a jelly-like consistency.

Pros:

  • Produces a bright, lively flame.

  • Easy to handle and store in small tins.

  • Minimal odour when burned.

  • No electricity, chimney, or gas connection required.

Cons:

  • Lower heat output than bioethanol.

  • Limited burn time per can.

  • Can cost more per hour of use if you’re running a fire frequently.

Best for: Occasional, decorative use where the look of the flame is more important than long heating hours.

2. Denatured Alcohol / Methylated Spirits

Another option is high-purity alcohol such as denatured alcohol (also called methylated spirits). These fuels share many of the clean-burning qualities of bioethanol.

Pros:

  • Readily available in hardware and camping shops.

  • Burns with a clean, low-odour flame.

  • Affordable compared to gel fuel.

Cons:

  • Can burn with a faint purple or blue flame rather than the golden glow of bioethanol.

  • Some blends include additives that increase odour.

  • Must be handled carefully due to its higher volatility.

Best for: Budget-conscious users who value cost savings and availability over visual flame quality.

3. Isopropyl Alcohol (Rubbing Alcohol, 70–99%)

While not as common for dedicated fire tables, isopropyl alcohol can be used in certain burners designed for liquid alcohol fuels.

Pros:

  • Easy to source in most countries.

  • Burns hot and fast, giving good initial warmth.

Cons:

  • Produces noticeable odour and occasional soot.

  • Shorter burn time compared to bioethanol.

  • Requires careful handling and ventilation.

Best for: Emergency or backup use rather than everyday ambience.

Key Factors to Consider When Choosing an Alternative

Not all fuels behave the same way. Before switching, weigh up what matters most to you:

  • Heat Output: Do you want a cosy warmth or just the atmosphere of a flame? Bioethanol and isopropyl alcohol burn hotter than gel fuel.

  • Flame Aesthetics: Bioethanol gives a bright, golden flame. Substitutes like denatured alcohol may look bluer or less full.

  • Odour & Emissions: Bioethanol is almost odourless. Alternatives can vary — gel is generally mild, isopropyl stronger.

  • Ease of Use: Pre-packed gel tins are simple. Liquid fuels require pouring and more careful handling.

  • Safety & Storage: Always store fuels in original containers, away from heat and children. Avoid overfilling burners and follow manufacturer instructions.

  • Cost & Availability: Bioethanol prices can rise, but bulk buying or exploring alternatives like denatured alcohol may help reduce running costs.

Safety First: What You Need to Know

Switching fuels isn’t just about performance — it’s about safe operation.

  • Check your burner: Not all burners are designed for substitutes. Using the wrong fuel can damage the fire or void warranties.

  • Ventilation matters: Even clean-burning fuels consume oxygen. Always use in well-ventilated spaces.

  • Never mix fuels: Stick to one type of fuel at a time to avoid unpredictable burning behaviour.

  • Cool before refuelling: Flames may be invisible in daylight — always ensure the burner is fully extinguished and cool before topping up.

Which Alternative Is Right for You?

  • If you want style and ease → Gel fuel is a simple, low-mess option.

  • If you’re budget-driven → Denatured alcohol is widely available and cost-effective.

  • If you need a backup in a pinch → Isopropyl alcohol works, but keep it for emergencies.

Final Thoughts

Bioethanol remains one of the cleanest and most stylish fuels for modern fires, but knowing the alternatives means you won’t be left in the cold if supply or cost becomes an issue.

Whether you prioritise design, efficiency, or affordability, there’s a substitute that can keep your flame alive. Just remember: always check your appliance’s fuel compatibility and follow safety best practices.
