Ethanol Fireplaces

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.

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.

⁠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.

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.

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.

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.

No, bioethanol fireplaces do not need electricity to operate. EcoSmart Fire bioethanol fireplaces run purely on liquid bioethanol fuel, with no power cord, no gas line, no flue, and no utility connections required.

That independence opens placement options a traditional fireplace cannot match. Without hardwired services, the fireplace can sit centred on a freestanding wall, inside bespoke joinery, on an apartment balcony, or anywhere a traditional fireplace simply can't go. Ignition is manual using the supplied Lighting Rod or Fire Lighter, a refillable butane wand, and the flame is adjusted by hand at the burner.

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.

Bioethanol fireplace heat output from EcoSmart Fire ranges from around 2 kW (6,180 BTU/h) for a compact burner to 13 kW (45,870 BTU/h) for a large multi-burner configuration, with efficiency greater than 90%. Because these fireplaces are ventless, no heat escapes up a flue, so all thermal output stays in the room.

Output scales with burner size and room volume:

• Compact burners: 2 kW (6,180 BTU/h), suited to spaces from about 15 m2 [161 ft2]
• Mid-range burners: 3 to 4 kW (11,430 to 15,290 BTU/h), covering 40 to 65 m2 [431 to 700 ft2]
• Large multi-burner Flex layouts: up to 13 kW (45,870 BTU/h), covering up to 195 m2 [2,099 ft2]

Adjustable-flame models let you modulate the output below maximum, and a single fill delivers 7 to 14 hours of burn time depending on flame height. Configured to the space, an EcoSmart Fire fireplace adds immediate, ambient warmth as a sculptural focal point. Output varies with flame height setting and installation configuration.

Yes, ethanol fireplaces are legal in Australia when they meet the Consumer Goods (Decorative Alcohol Fuelled Devices) Safety Standard 2017, the country's mandatory product safety rule for clean-burning bioethanol fireplaces. Full-size models that satisfy the weight, footprint, and stability requirements are sold and installed lawfully across every Australian state and territory.
