Ethanol Fireplaces

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.

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.

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.

As a room-vented design, ventless bioethanol fireplaces are regulated under product safety standards (UL 1370, EN 16647, ACCC) rather than traditional building codes that govern gas or wood-burning installations. EcoSmart Fire ventless fireplaces meet these safety standards and require no chimney, gas lines, or electrical hookups, which eliminates many code compliance complexities. Because bioethanol combustion produces no smoke or harmful emissions, ventless fireplaces bypass venting and structural requirements that apply to conventional fireplaces.

Regulations do vary by jurisdiction, so we recommend consulting your local building authority during the design phase to confirm any region-specific requirements for your project. Key installation specifications, such as 600 mm [23.6 in] clearance from combustibles and adequate room volume (typically 40–110 m³ for most residential models), are designed to ensure safe operation and are integrated into all EcoSmart Fire product documentation.

The ventless design simplifies the approval process because it eliminates the need for multiple trades (gas fitting, electrical, ventilation) and their associated code pathways. This makes ventless fireplaces particularly practical for retrofits, multi-residential applications, and properties where traditional fireplaces aren't viable.

Yes, room-vented bioethanol fireplaces do produce water vapour through combustion, and condensation can occur in spaces that are undersized or poorly ventilated. EcoSmart Fire's design addresses this directly: minimum room volume requirements are scaled to each burner's heat output, ensuring moisture disperses safely across the air volume rather than accumulating on surfaces.

Smaller burners (around 4 kW) need at least 110 m³ [3,885 ft³], whilst larger burners (13 kW) require 330 m³ [11,654 ft³] or more. This scaling ensures combustion byproducts, including water vapour and carbon dioxide, are diluted proportionally to the burner's output.

In properly sized rooms with normal air circulation (doors, windows, existing HVAC), condensation is not an issue. Problems arise only when a fireplace is oversized for its space or installed in a room with poor air exchange; matching the burner size to the room prevents either outcome.

Separately, ambient moisture from external sources, such as humid storage environments or spilled water, can contaminate the burner reservoir and prevent ignition. This is a maintenance concern distinct from normal combustion, resolved by draining, drying, and refuelling with fresh bioethanol.

Clean-burning bioethanol fireplaces in Australia must comply with the Consumer Goods (Decorative Alcohol Fuelled Devices) Safety Standard 2017 (Federal Register reference F2017L00909). Introduced in July 2017 and enforced by the ACCC, it applies in every state and territory and uses the European standard EN 16647:2015 as its technical benchmark.

To comply, a bioethanol device must be permanently fixed, or have a dry weight of at least 8 kg with a footprint of 900 cm² or more. The fuel system must include a flame arrester or an automatic fuel pump, and the unit must carry the prescribed permanent safety warning.

EcoSmart Fire bioethanol fireplaces are built to satisfy this standard, alongside UL 1370 listing and EN 16647 BSI certification.

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

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.

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.

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.
