Ethanol Fireplaces

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.

Bioethanol and gas ventless fireplaces differ fundamentally in combustion emissions, infrastructure requirements, and fuel delivery, making them suited to different priorities and spaces.

EcoSmart Fire bioethanol fireplaces are approved for both indoor and outdoor use. Their combustion produces only water vapour and minimal CO₂, with no smoke, soot, or toxic gases entering your living space. Gas ventless fireplaces, by contrast, release carbon monoxide and nitrogen dioxide indoors, which is why they're limited to outdoor use only. This emissions difference is the core distinction: bioethanol's clean burn supports indoor air quality; gas requires outdoor deployment.

Infrastructure-wise, bioethanol fireplaces need no gas line connection; you refuel manually from e-NRG bottles. Gas ventless models require a permanent liquefied petroleum or natural gas line, professional installation, and annual inspection and servicing. If your space has no existing gas infrastructure, bioethanol eliminates the cost and complexity of installation.

Maintenance also differs. Bioethanol requires cleaning after the first 50 litres of fuel burned and then periodically depending on usage. Gas units demand annual professional servicing and vent checks. Both achieve ~90% thermal efficiency, but bioethanol's user-managed refuelling and maintenance suit flexibility-conscious owners; gas suits those with existing supply and regular service budgets.

Your EcoSmart Fire ethanol fireplace will burn between 8 and 13 hours on a full burner, with the exact duration determined by your flame setting. The range gives you control over the experience.

A lower flame setting extends burn time and creates a subtle, intimate ambience perfect for a long evening. Higher flame settings deliver a more dramatic visual impact and warmth, though they'll reduce runtime. Adjusting the flame via the slide or hinge mechanism changes oxygen supply to the burner, so you get more hours of gentle glow or fewer hours of bold presence, whatever suits the occasion.

You can also extinguish the burner mid-burn if needed. Simply turn it off and allow the burner to cool for 60 minutes before relighting. The vapours need that cooling time.

The burner capacity varies across our range, so compact models sit toward the lower end of the 8–13 hour spectrum while larger burners reach the upper end.

Ethanol fireplaces work by burning bioethanol fuel, a clean-burning renewable alcohol made from fermenting plant sugars, in a self-contained, stainless-steel burner. When you ignite the fuel with a lighting rod, it combusts at the fuel surface, producing heat, water vapour, and minimal CO₂; there's no smoke, soot, or ash.

The real innovation is in flame stabilisation. EcoSmart Fire burners use physical regulators, including steel wool in compact models like the AB3 and baffle inserts in larger burners, to control fuel evaporation and distribute the flame evenly. This not only stabilises the flame but optimises fuel efficiency, extending burn times to 7–13 hours depending on burner size and capacity.

Shutting down is equally straightforward. A slider or hinge mechanism closes off oxygen, extinguishing the flame in seconds without any residual smoke or smell. Because combustion requires no flue, chimney, or gas line, ethanol fireplaces are truly ventless; the burner stays sealed until you're ready to refuel.

This combination of clean combustion chemistry and elegant mechanical control is what makes ethanol fireplaces such a flexible heating and ambience solution.

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.

Yes, you can turn off your EcoSmart Fire bioethanol fireplace at any time, even if fuel remains in the burner. Simply close the slider or lift the lid to shut off the flame immediately. The shut-off mechanism is designed for your control, particularly in situations where you need to leave the house, since it's not safe to leave a burning fireplace unattended.

For best results when relighting, wait at least 60 minutes after extinguishing to allow vapours to dissipate. This prevents a strong initial ignition when you restart the flame. If you need to refuel after extinguishing, the burner must be cool to room temperature before adding fresh bioethanol. These waiting periods are simply the correct way to use the fireplace responsibly, ensuring a smooth relight and safe operation.

Yes, ethanol fireplaces produce genuine, clean-burning heat that meaningfully warms spaces. EcoSmart Fire bioethanol fireplaces deliver quantified heat output across burner sizes: compact burners like the AB3 produce 2 kilowatts (5,800 BTU/h) and warm spaces around 20 m² [215 ft²], whilst larger models like the XL900 output 4 kilowatts (15,000 BTU/h) and effectively heat areas up to 60 m² [646 ft²].

The real advantage lies in the ventless design: heat efficiency exceeds 90 per cent because all thermal energy stays in your room, unlike traditional vented fireplaces that lose approximately 30 per cent through the chimney.

To choose the right burner, match it to your room size. Smaller burners suit compact rooms around 20 m², mid-range burners heat spaces of 40–60 m² comfortably, and larger configurations work for open-plan interiors. Burner selection also affects burn duration, with most models running 7–14 hours depending on flame height; consider both your heating needs and intended use.

EcoSmart Fire bioethanol fireplaces run on e-NRG fuel, available here .
⁠The actual cost per hour depends on your burner size and flame adjustment.

Consumption ranges from 0.31 litres per hour on compact burners to 1.1 litres per hour on larger models. Using a mid-size burner at full flame, an evening's three to four hours of operation costs approximately USD $10-15. If you adjust the flame to lower settings, consumption drops by 30-50%, extending burn time and reducing fuel costs proportionally. A 5-litre fill typically provides 7–14 hours of burn time, depending on your flame setting and burner size.

The appeal of bioethanol is predictable operational cost with no installation complexity. You’re not financing chimney construction, gas plumbing, or annual servicing. You’re buying fuel when you want to use the fireplace. Bioethanol’s 90-95% thermal efficiency means more of the fuel’s energy becomes usable heat, rather than escaping up a flue. Your actual running cost sits well below traditional fireplaces when you factor in the installation and maintenance savings.

For cost-conscious buyers, adjustable flame control is a practical tool. Lowering the flame doesn’t diminish the visual impact significantly, but it can cut your fuel consumption and cost by nearly half.

Like all fireplace solutions, bioethanol fireplaces can be safe with proper precautions around children and pets. EcoSmart Fire recommends installing certified fire screens, maintaining safe distances from hot surfaces, and never leaving the fire unattended. Children should always be supervised, and pets kept away from the unit during operation due to high surface temperatures.

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.
