Ethanol Fireplaces

EcoSmart Fire ethanol fireplaces produce minimal odour during normal operation. You may notice a brief, faint scent when lighting or extinguishing, comparable to blowing out a candle. This is caused by denaturants in the fuel that prevent human consumption. The scent's intensity depends entirely on fuel quality.

EcoSmart Fire fireplaces are engineered exclusively for e-NRG Bioethanol, formulated to 96-97% purity with odour-minimising denaturants that reduce fusel alcohols (compounds creating unpleasant smells in lower-grade fuels) to barely perceptible levels. Using other fuels may affect performance and warranty coverage.

If you ever notice an unusual smell, the fix is straightforward: ensure you're using e-NRG Bioethanol and that the burner is clean and debris-free. Once properly fuelled, the smell will not return.

A ventless ethanol fireplace works through complete combustion of bioethanol vapour, burning cleanly into heat, water vapour, and minimal CO₂ with no flue or chimney required. Unlike traditional fireplaces, no external ventilation infrastructure is needed.

Bioethanol is pure ethanol fuel (96–97% alcohol by volume), produced through fermentation of corn and plant sugars. When liquid bioethanol sits in the burner tray and is lit, it vaporises and burns above the burner surface, creating a real, visible flame. Because the process is nearly complete oxidation (ethanol vapour combining with oxygen drawn from the room), it generates no soot, smoke, or ash.

The byproducts, primarily heat, water vapour, and the same CO₂ humans exhale, discharge directly into the living space. This room-vented principle is what eliminates the need for a chimney or external vent. Because no heat is lost through a flue, ethanol fireplaces typically achieve thermal efficiency above 90%.

When bioethanol is sourced from sustainably managed renewable feedstock, the carbon cycle is considered carbon-neutral, as CO₂ released during combustion approximately balances what the source crops absorbed during growth.

Bioethanol fireplaces with adjustable flame control do not require a chimney, flue, or permanent ventilation system. The clean combustion of bioethanol releases only water vapour and a small amount of carbon dioxide, with no smoke or soot that would need extraction through a dedicated exhaust pathway.

What replaces the chimney is adequate room volume and natural air infiltration. Minimum room sizes are specified per burner. In very compact rooms, a window openable to 25 mm [1 in] or an adjacent open door provides sufficient air exchange.

This chimney-free design underpins the installation freedom EcoSmart Fire bioethanol fireplaces are known for: zero-clearance inserts, freestanding pieces, and existing fireplace conversions all become viable without structural works.

Bioethanol fireplaces are environmentally friendly in ways that go beyond zero emissions. They produce no ash, soot, or residue, leaving nothing to dispose of, and their ventless design eliminates the environmental cost of infrastructure like chimneys, flue systems, or gas plumbing. The fuel comes from renewable agricultural byproducts: sugarcane, corn, grain, and beetroot.

Because combustion releases only the CO2 that the crops absorbed during growth, the fuel cycle is carbon-neutral. When combined with the fireplace's design durability and longevity, a bioethanol fireplace becomes a low-impact choice for years of use. EcoSmart Fire products meet international safety standards (UL 1370-16, EN 16647) and carry sustainability certifications across manufacturing, reinforcing the brand's commitment to responsible production.

Room-vented ethanol fireplace running costs depend on burner size and flame height, since combustion directly controls fuel consumption. Smaller burners consume around 0.31 litres per hour at minimum flame, mid-range around 0.5 L/h, and larger burners up to 1.1 L/h at full flame. At current bioethanol fuel pricing (typically USD $4-6 per litre retail), this translates to roughly $1.24-$6.60 per hour depending on the model and flame setting you choose.

The room-vented design gives you a real cost advantage: because there is no flue, 100 per cent of the combustion heat stays in the room. Every litre of fuel delivers its full thermal output directly into your space, with no heat loss up a chimney. This means lower fuel bills compared to traditional fireplaces at the same comfort level.

To minimise running costs, simply lower the flame height. Flame control is your cost control: it directly reduces consumption. For bulk fuel purchasing (200 litres or more), per-litre pricing drops significantly. Check e-nrg.com for current pricing and bulk rates.

Ventless bioethanol fireplaces deliver room-vented performance without any of the infrastructure traditional installations require. There is no chimney, flue, or gas line, and combustion is clean, producing no smoke, soot, or ash. The gains are real: heat stays in the room rather than escaping through a flue, and the fireplace can be positioned almost anywhere, from apartments to open-plan living spaces. Managing the trade-offs is equally clear. Bioethanol combustion consumes oxygen, so the room must meet manufacturer-specified minimum volumes, and ventilation needs to remain adequate during use. These fireplaces are designed for supplemental heating, not as a primary heat source, and they require ongoing refuelling since no fuel line connects them. For spaces where a traditional fireplace is impractical, the room-vented ventless format offers genuine design freedom. The cost of that freedom is active fuel management and attention to room conditions during operation, both of which are clearly outlined in EcoSmart Fire's product documentation and third-party certified safety standards.

Bioethanol fireplaces produce no carbon monoxide during normal operation. Complete combustion converts bioethanol entirely into water vapour and carbon dioxide, and adjustable flame control across EcoSmart Fire's operating range does not alter this chemistry.

Carbon monoxide results from incomplete combustion, when insufficient oxygen prevents full oxidation of the fuel. EcoSmart Fire burners maintain complete combustion across the full output range. The flame arrestor integrated into the burner prevents fuel vapour flashback and sustains consistent burn conditions throughout each session.

Combustion by-products are carbon dioxide and water vapour, the same gases produced by normal breathing and candle combustion. UL 1370 (USA) and EN 16647 (Europe and UK) independently validate that EcoSmart Fire fireplaces meet safety thresholds for unvented indoor use.

Room-vented bioethanol fireplaces deliver multiple environmental benefits that begin with the fuel itself. Bioethanol's carbon profile is fundamentally different from fossil fuels: the CO2 released during combustion is equivalent to what the source plants absorbed during photosynthesis, cycling existing atmospheric carbon rather than releasing sequestered fossil carbon. The bioethanol used in EcoSmart Fire fireplaces is derived from agricultural by-products and surplus crop production, positioning it as a renewable resource rather than a dedicated energy crop.

Combustion produces only CO2 and water vapour, leaving zero particulates, soot, ash, or harmful gases. Unlike vented fireplaces that lose heat up a chimney, the room-vented design retains all combustion heat within the space, reducing the fuel needed to achieve the same comfort level compared to traditional wood or gas alternatives.

The absence of flue infrastructure eliminates ongoing environmental costs: no chimney maintenance, no structural engineering for venting systems, and no dependency on gas supply chains or electricity grids powered by fossil fuels. From production to operation to end of life, bioethanol fireplaces offer a resource-efficient alternative aligned with sustainable design principles.

Bioethanol fireplace emissions are limited to heat, water vapour, and a small amount of carbon dioxide, with no carbon monoxide, smoke, soot, or ash produced during combustion. The CO2 released is roughly equivalent to two burning candles, which means correctly sized rooms maintain clean indoor air without a flue or chimney.

Clean combustion does depend on fuel purity. High-grade e-NRG bioethanol burns as a complete reaction, producing a steady orange flame from start to finish without the residues that lower-purity fuels leave behind. That's why EcoSmart Fire bioethanol fireplaces won't stain ceilings, dull nearby finishes, or leave ash to clean up between uses.

What the by-products look like in practice:

• Water vapour: a slight, imperceptible rise in humidity, not visible condensation in a correctly sized room
• Carbon dioxide: trace amounts, comparable to candlelight at the same output
• No particulates: no smoke, no soot, no ash, no odour

Ventilation is about keeping fresh oxygen available for combustion, not venting harmful gases. Each burner has a minimum room size, from the VB2 at 45 m3 [1,589 ft3] up to the AB8 at 116 m3 [4,097 ft3], so adequate air supply is a matter of considered installation

Ethanol fireplaces typically don't require building permits in most jurisdictions because the ventless design avoids the restrictions that apply to traditional fireplaces. Since there's no chimney, gas line, or flue to regulate, ethanol fireplaces fall outside the strict building codes created for wood and gas systems. EcoSmart Fire products carry UL 1370 and EN 16647 certification, meeting the safety standards most building authorities reference, which often results in automatic exemption from permit requirements.

Where to verify for your location:

• Contact your local building authority directly with your address and installation plan. Most can confirm permit status in one conversation.
• If you're in an apartment, managed community, or strata scheme, notify your body corporate or residents' committee. Whilst permits may not be required, the organisation may want advance notice of the addition.
• Check with your home insurer. Most policies cover ethanol fireplaces without additional riders, but confirming coverage beforehand simplifies the process should a claim arise.

Jurisdictional variation is minimal. With over 150,000 EcoSmart Fire installations across North America, Europe, the UK, and Australia since 2004, the regulatory picture is consistent: ethanol fireplaces gain approval where they're assessed against safety standards rather than traditional fireplace codes. If your jurisdiction does impose conditions, they're typically straightforward ventilation or room-volume requirements, not permit blockers.
