What Is Bioethanol Fuel? A Complete Guide for Fireplace Owners
Bioethanol fuel powers modern ventless fireplaces with real flames, zero smoke, and no chimney required. It's the reason you can install a fireplace virtually anywhere - living rooms, bedrooms, media walls, even apartments without flues.
But not all fuel is created equal. The purity, manufacturer, and formulation affect everything from burn time, to odour, to warranty coverage. Choose the wrong fuel, and you risk poor performance, unpleasant smells, or voiding your guarantee.
This guide explains what bioethanol fuel actually is, how much it costs to run (real figures), how to store it safely, and which brand to choose for your specific fireplace.
Understanding Bioethanol Fuel
At its core, bioethanol is plant-based ethanol (ethyl alcohol, C2H5OH) - the same alcohol found in alcoholic drinks, but denatured to make it unfit for consumption. It's produced through fermentation of biomass, typically sugarcane, corn, or other crops.
For fireplace use, the fuel must reach 96.6% purity through multiple rectification processes. This pharmaceutical-grade standard ensures clean combustion without smoke, soot, or toxic by-products.
Why Bioethanol Is Carbon Neutral
Unlike fossil fuels that release stored carbon, bioethanol is part of a closed cycle. The plants absorb CO2 during growth. When you burn the fuel, that same CO2 returns to the atmosphere. The net effect is zero additional carbon - making bioethanol fuel environmentally friendly compared to gas, coal, or oil.
What Happens When You Burn It?
Complete combustion of bioethanol produces three things:
- Heat - at 90%+ efficiency (gas boilers achieve 60-80%)
- Water vapour - slight humidity increase, minimal
- Carbon dioxide - offset by plant absorption, so carbon neutral
Notice what's missing: no smoke, no ash, no soot, no particulates, no creosote. This is why bioethanol fireplaces need no chimney, flue, or external venting.
Manual vs Automatic Fireplaces: The Fuel Difference
Manual fireplaces burn liquid fuel directly. The flame heats the ethanol to around 80°C, producing vapours that combust. Some vapours escape before burning, which can create slight odour - especially with lower-quality fuel.
Automatic fireplaces (like Planika's BEV technology) convert liquid to vapour before combustion using an integrated generator. This vapour burns completely with no odour and maximum efficiency. Important: Never use 100% ethanol in automatic fireplaces - the purity can damage electrical components. Always use formulated fuel at 96.6-97%.
Pick Fanola if:
- You own any Planika automatic fireplace (Neo, FLA4, FLA4+, Primefire, Panorama, Forma)
- You want to keep your warranty intact
- You prioritise minimal odour
- You want EU environmental certification
Pick e-NRG if:
- You own an EcoSmart fireplace or any other manual fireplace
- You have a manual fireplace (check compatibility first)
- You want a particularly vibrant flame aesthetic
⚠️ Critical: Using the Wrong Fuel Voids Your Warranty
Planika explicitly requires Fanola for their automatic fireplaces. Using e-NRG or other brands may invalidate your warranty and can damage electrical components. For manual fireplaces, you have more flexibility — but always check your user manual.
The True Cost of Running a Bioethanol Fireplace
Let's talk numbers. Bioethanol fuel isn't cheap, but it's predictable. Here's what you'll probably spend.
Current Fuel Prices (2026)

Hourly Running Costs by Burner
Different burners consume fuel at different rates:
| Burner | Consumption | Cost/hour | Typical evening (4 hrs) |
|---|---|---|---|
| Neo 1000 | ~0.7L/hr | ~£2.80 | ~£11.20 |
| FLA4 990 / Primefire | ~0.75L/hr | ~£3.00 | ~£12.00 |
| FLA4+ 990 (economy mode) | ~0.5L/hr | ~£2.00 | ~£8.00 |
Weekly, Monthly, Annual Costs
Assuming you use your fireplace 4 hours per night, 5 nights per week (typical weekday evening use):
- Weekly: £40-60 (depending on burner model)
- Monthly: £160-240
- Yearly: £1,920-2,880 (based on consistent autumn/winter use)
Summer usage is typically lower, so real annual costs may be £1,400-2,000 for most households.
💡 How to Reduce Fuel Costs
The FLA4 range lets you adjust flame height. Running at 50-60% power cuts consumption to ~0.5L/hour - saving you £40-60 per month compared to maximum output. You still get beautiful flames and adequate heat, just more economically.
Storing Bioethanol Fuel Safely
Fuel storage is straightforward but important. Here's how to do it right.
Storage Requirements
- Keep in original containers - they're designed for safe storage
- Cool, dry location - away from heat sources, sunlight, ignition
- Out of reach - children and pets shouldn't access it
- Well-ventilated area - garage, shed, or utility room is ideal
- Upright position - prevents leakage
Shelf Life - Stored correctly, bioethanol fuel lasts 2-3 years. Keep containers sealed, avoid temperature extremes, and discard if fuel appears cloudy or contaminated.
Transportation Tips
- Ensure containers are tightly sealed
- Keep upright and secure in your vehicle
- Don't leave in direct sunlight for extended periods
- Never transport with ignition sources (cigarettes, lighters)
Safety Guidelines
Bioethanol is safe when handled properly. Follow these rules.
Refuelling Your Fireplace
- Only refuel when completely cool - never add fuel to a hot or burning fireplace
- Don't overfill - leave expansion room in the tank
- Clean spills immediately - wipe any spilled fuel before lighting
- Store fuel away from the fireplace during refuelling
-
Follow manufacturer's guidance - you should always get a user manual
During Operation
- Never move a lit fireplace - wait until fully cooled
- Maintain clearances - keep curtains, furniture, fabrics away
- Ensure ventilation - 1 air change per hour (modern homes achieve this naturally)
- Supervise the fire - don't leave burning for extended periods unattended
If You Spill Fuel
- Extinguish any flames immediately
- Ventilate the area thoroughly
- Absorb with cloth or paper towels
- Dispose of contaminated materials safely
- Don't relight until area is completely dry and vapour-free

High-quality fuel like Fanola and e-NRG produce minimal to no odour in automatic fireplaces. Manual fireplaces may have slight odour during lighting and extinguishing, but this dissipates quickly. If you notice persistent smells, check your fuel quality - cheap or contaminated fuel is usually the culprit.
Yes - it's classed as carbon neutral. The plants absorb CO2 as they grow. When burned, that CO2 returns to the atmosphere. Nett effect: zero additional carbon. Plus, no smoke, soot, or particulates means cleaner local air quality than wood or coal.
Automatic fireplaces display fuel levels on the control panel or via smartphone app. Burn times vary by model: Neo lasts up to 4 hours, FLA4/Primefire up to 8-9 hours, FLA4+ up to 26-30 hours. Never let the tank run completely dry - refill when the low-fuel warning appears. Always make sure the fire is off before you refuel.
Not recommended. Different manufacturers use slightly different formulations and additives. For best performance and warranty compliance, stick with one brand.
Bioethanol freezes at -114°C - far below any UK winter temperature. However, extreme cold can make containers brittle. Store at normal room temperature for best results.
Extinguish flames immediately, ventilate the area, absorb with cloth or paper towels, and dispose of contaminated materials safely. Don't relight until the area is completely dry and vapour-free. For large spills, contact your local authority for disposal guidance.
