Bioethanol Fuel

Bioethanol fuel produces only heat, water vapour, and carbon dioxide when burned: no smoke, soot, or ash. You may notice a minimal, barely perceptible scent only at ignition and extinguishing; this is normal for high-quality ethanol formulations.

Unlike wood fires or traditional gas fireplaces, e-NRG bioethanol fireplaces produce no residue or emissions that damage surrounding surfaces or degrade indoor air quality. The combustion process is clean and complete, certified to UL 1370 (USA), EN 16647 (Europe/UK), and ACCC safety standards (Australia). This makes them safe for indoor and ventless installation.

Adequate ventilation is required because any fire consumes oxygen: minimum 5.7 m³ [200 ft³] of air per 1,000 BTU/hour of appliance rating. If your room is smaller than this volume, you can crack a window to at least 25.4 mm [1 in.] or leave doors to adjacent rooms open. Like any combustion appliance, consider consulting a physician if anyone in your household has significant respiratory sensitivities; this applies equally to wood fires or gas appliances. Always use e-NRG branded fuel to ensure consistent, clean combustion. Non-approved fuels may affect emission performance.

If your order includes e-NRG and EcoSmart Fire, you will receive a separate confirmation for e-NRG. We do our best to closely align the delivery of each shipment so you can begin using your EcoSmart Fire immediately.

e-NRG bioethanol is a high-quality, clean-burning fuel specifically formulated for use in liquid ethanol-fuelled ventless fireplaces. Also known as denatured alcohol or ethanol, bioethanol is a naturally derived fuel made from fermented plant sugars. e-NRG is the only brand of bioethanol that has been tested with and recommended for use in EcoSmart Fire burners. The burning of this fuel creates nothing more than heat, water vapour and carbon dioxide – a cleaner heating solution for you and the environment.

Bioethanol fuel doesn't expire abruptly, but it does degrade over time. e-NRG bioethanol maintains full potency for three years when stored in sealed, unopened containers, but degradation accelerates once containers are opened or exposed to heat and light.

To assess whether your fuel is still usable, look for signs of degradation: discolouration, a noticeably different smell, or visible separation in the container. These indicate moisture absorption or chemical breakdown. If the fuel looks and smells normal, it's safe to use; if you're uncertain, dispose of it safely and purchase a fresh supply.

Sealed containers last longer than opened ones. Once opened, fuel begins absorbing moisture from the air, shortening its shelf life considerably. Storage temperature matters too: keeping fuel around 20°C (68°F) in a basement extends longevity, while temperature swings above 25°C accelerate evaporation. Never store fuel in direct sunlight or near heat sources.

e-NRG bioethanol is a renewable energy source produced from 96–97% pure ethanol by volume, with the remainder consisting of water and safety denaturants. The fuel is made by fermenting dedicated corn crops to convert plant sugars into ethanol, then refined through multi-stage distillation to precise specifications.

This narrow purity range is engineered for performance and safety. Below 96%, incomplete combustion creates odours and soot, requiring extra maintenance. Above 97%, the fuel evaporates too rapidly, potentially compromising burner seals. The 96–97% range is the engineered sweet spot that balances thermal efficiency with reliability.

The denaturants (such as Bitrex or methanol) are added at minimal levels to meet safety compliance requirements without affecting flame quality or odour. e-NRG’s production chain includes batch testing for impurities and moisture, ensuring consistent quality across every bottle.

When burned, e-NRG bioethanol combusts cleanly to produce only heat, water vapour, and carbon dioxide. There is no soot, smoke, ash, or toxic emissions. The process is carbon neutral: the CO₂ released during combustion equals the CO₂ absorbed by the corn crops during growth.

No, you don't need a traditional chimney or flue. That's why bioethanol burners are called "ventless." However, like any open flame, a bioethanol burner does consume oxygen and produces carbon dioxide and water vapour, so adequate fresh air circulation is essential.

Unlike wood or gas fireplaces that require a dedicated flue, e-NRG bioethanol burners need no structural ventilation system. As a renewable energy source, bioethanol burns cleaner than fossil fuels, but the ambient air exchange requirement remains: simply cracking a window or ensuring natural air circulation prevents oxygen depletion and CO₂ build-up.

The practical requirement depends on burner capacity. Smaller burners perform well in rooms of 40 cubic metres [1,413 cubic feet] with a slightly open window; larger models (up to 110 cubic metres [3,885 cubic feet]) require proportionally more air circulation. The key is ensuring the space can exchange air naturally, whether through a cracked window (around 25 mm), a vent, or existing room ventilation.

Think of it like this: any flame consumes oxygen. Bioethanol's clean combustion means no toxic emissions, but the chemistry still requires fresh air. A slightly opened window is usually sufficient.

No. As a renewable energy source, e-NRG bioethanol combustion produces no toxic compounds. Unlike wood fires (which emit carbon monoxide and particulates) and gas systems (which produce nitrogen oxides), bioethanol burns completely to heat, water vapour, and minimal CO₂, the same byproducts of human respiration.

Bioethanol's clean combustion comes from its molecular structure: when pure ethanol (96–97% alcohol content) burns, it undergoes complete oxidation with oxygen, leaving no carbon monoxide, nitrogen oxides, volatile organic compounds, or particulate matter. This is why bioethanol fireplaces operate safely indoors without requiring a flue or external venting to remove toxins.

The distinction matters for indoor air quality. Wood fires release carcinogenic particulates that settle on surfaces and linger in air. Gas heaters produce invisible nitrogen oxides requiring ventilation. Bioethanol eliminates both hazards at the combustion stage. There is nothing toxic to vent away.

Ventilation requirements for e-NRG installations address oxygen replenishment for room air quality, not toxin removal. This safety feature, combined with UL 1370 certification, makes bioethanol fireplaces suitable for indoor and outdoor use without the air quality compromises of traditional heating.

Bioethanol can be wiped up with either a paper or cloth towel. Paper towels can be disposed of in regular trash bins. Though not toxic, it is recommended that you wash hands immediately after coming into contact with e-NRG.

Store bioethanol fuel in approved containers at a cool, stable temperature between 15–25°C [59–77°F] to preserve purity and combustion performance. For residential use, most jurisdictions permit up to 20 litres [5 gallons] of bioethanol indoors without special permitting; anything beyond this requires an approved flammable liquid storage cabinet with double-walled construction and spill containment.

Keep fuel in tightly sealed containers in a well-ventilated area away from heat sources, direct sunlight, and ignition sources (sparks, electrical outlets, open flames). A basement or cool cupboard works well; avoid attics and uninsulated sheds where temperature fluctuates. Temperatures above 25°C accelerate evaporation and reduce shelf life, so consistent cooling preserves the fuel’s effectiveness longer.

e-NRG bioethanol maintains full potency for three years in sealed containers; proper storage extends this reliability. Transfer fuel using approved jerry cans with safety spouts and use bonding straps if handling large volumes to prevent static discharge, a critical safety practice for any flammable liquid.

Never pour fuel over open flames or fill appliances directly from the storage container. For spills and disposal, follow your local environmental and fire safety guidelines, as requirements vary by jurisdiction.

For detailed regulatory guidance, consult your local fire authority or relevant safety standards body. In Australia, AS 1940:2017 governs flammable liquid storage requirements.
