Question 1

How does a ventless ethanol fireplace work?

Accepted Answer

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.

Question 2

Can ethanol fireplaces be used outdoors?

Accepted Answer

Yes. EcoSmart Fire offers dedicated outdoor fireplace categories: fire tables, fire pits, and insert-style units, all rated for outdoor use. These are engineered with weather-resistant materials: mild steel with zinc-sealed high-temperature powder coating, 304-grade stainless steel burners, and toughened glass screens. Fire tables feature handcrafted Fluid Concrete surrounds or Grade A teak; fire pits use weather-resistant Fluid Concrete construction.

To install safely outdoors, follow these clearance guidelines:

2,000 mm [78.7 in] clearance overhead
600 mm [23.6 in] clearance from fixed objects (walls, fences, railings)
Level, non-combustible surface (stone, concrete, pavers; not grass or artificial turf)
12.5 mm [0.5 in] air gap beneath the unit, typically via articulating feet

Because bioethanol produces no sparks, embers, or ash, the units are safe for timber decks when proper clearances are maintained. They're suitable for year-round entertaining. Simply keep burners clean every 50 litres of fuel, and use an All-Season Cover (600D Oxford fabric with UV coating) for storage.

Question 3

What is Australia's mandatory safety standard for ethanol burners? (AU)

Accepted Answer

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, and the burners are O-TL listed to UL 1370.

Question 4

How much does bioethanol fuel cost?

Accepted Answer

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.

Question 5

Can I refill my bioethanol fireplace while it's running?

Accepted Answer

No, never refuel your EcoSmart Fire bioethanol fireplace while it's running or hot. Bioethanol requires careful handling: even if the flame isn't visible, a common occurrence in daylight, the burner remains dangerously hot and volatile vapours persist long after the flame appears extinguished. Contact with any ignition source at this stage can cause serious injury.

Always allow the fireplace to cool completely for at least 60 minutes after shutting off before refuelling. The cool-down is part of the rhythm of responsible ownership. When refuelling, use only the approved Safety Nozzle adapter or Jerry Can with Safety Spout, never pour directly from a bottle over or near the burner. If you spill fuel, remove all ignition sources, open windows and doors for ventilation, wipe the area dry, and wait until it's completely dry before relighting.

UL 1370-certified EcoSmart Fire bioethanol fireplaces are designed for safe indoor use when operated correctly. Pairing the correct cool-down protocol with e-NRG bioethanol fuel ensures consistent performance and safety.

Question 6

Are ethanol fireplaces legal in Australia? (AU)

Accepted Answer

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.

The 2017 standard, administered by the ACCC, sets minimum physical specifications and references EN 16647:2015 for performance and safety. It permits compliant freestanding, wall-mounted, and built-in bioethanol fireplaces. All EcoSmart Fire bioethanol fireplaces meet and exceed the mandatory minimum thresholds of 8 kg and 900 cm², and are independently tested to international standards recognised under the regulation.

Buy from a manufacturer that publishes its compliance documentation, and check that the model carries the Australian standard alongside its international certifications.

Question 7

Are there any building codes or regulations for ventless fireplaces?

Accepted Answer

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.

Question 8

Do bioethanol fireplaces need a chimney or flue?

Accepted Answer

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.

Question 9

Do ethanol fireplaces produce enough heat?

Accepted Answer

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.

Question 10

Can you cook on a bioethanol fireplace?

Accepted Answer

Bioethanol fireplaces are purpose-engineered as decorative appliances, delivering real, adjustable flame ambience without a chimney, gas line, or installation. They are not designed for cooking.

Their burners produce variable, dancing flames optimised for atmosphere, not the consistent, controlled heat that food preparation requires. The burner containers are designed to display flame elegantly, not for direct food contact. There are no temperature controls, cooking grates, or heat-resistant surfaces suited to cookware placement.

EcoSmart Fire bioethanol fireplaces are UL-listed as ventless decorative appliances, which is what they do best: transforming indoor and outdoor gathering spaces with real, clean flame that is immediate, zero-installation, and endlessly adaptable to any setting.

Question 11

Can I extinguish the ethanol fireplace before the fuel has burnt?

Accepted Answer

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.

Question 12

What gases and emissions does a bioethanol fireplace produce?

Accepted Answer

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

Question 13

Are bioethanol fireplaces environmentally friendly?

Accepted Answer

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.

Question 14

Do ethanol fireplaces smell?

Accepted Answer

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.

Question 15

Are ventless fireplaces safe?

Accepted Answer

Ventless bioethanol fireplaces from EcoSmart Fire are safe when properly installed and operated according to guidelines. Unlike gas ventless fireplaces, bioethanol produces only water vapour, heat, and CO2 (comparable to a burning candle), with no carbon monoxide, smoke, soot, or harmful gases. EcoSmart Fire units include integrated safety features: a manual shut-off system, safety glass windscreens, and flame arrestor fuel bottles designed to minimise spill risk. Independently certified to UL 1370-16 and EN16647, the brand has deployed thousands of units across luxury hotels, resorts, and multi-residential buildings globally for over two decades. Proper room sizing and adequate ventilation are essential; refer to product specifications for your model's requirements.

Question 16

Can ventless fireplaces be used as a primary heat source?

Accepted Answer

Ventless bioethanol fireplaces from EcoSmart Fire are designed as supplemental, not primary, heat sources, delivering 2–4 kW for zone-specific warmth. An XL900 burner generates 4 kW and heats approximately 60 m² [646 ft²] effectively. EcoSmart Fire's closed-combustion design retains 100% of generated heat within the room, unlike vented gas systems that lose up to 30% through flues, making every kilowatt of output directly useful. Because combustion draws on room oxygen, adequate room ventilation is required during operation; EcoSmart Fire specifies minimum room volumes for each fireplace to maintain indoor air quality. This design is intentionally optimised for room-scale supplemental heating rather than whole-home continuous output. For whole-home heating, a dedicated primary system remains essential. For creating focal-point warmth in a living room, study, or outdoor entertaining space, EcoSmart Fire fireplaces deliver meaningful, design-forward heat with a fuel consumption rate as low as 0.31 L/h for smaller burners.

Question 17

How long will my ethanol fireplace burn?

Accepted Answer

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.

Question 18

Do bioethanol fireplaces need electricity to operate?

Accepted Answer

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.

Question 19

What are the environmental benefits of ventless ethanol fireplaces?

Accepted Answer

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.

Question 20

Are ventless ethanol fireplaces different from ventless gas fireplaces?

Accepted Answer

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.

Question 21

Are bioethanol fireplaces safe for homes with children or pets?

Accepted Answer

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.

Question 22

How much does it cost to run a ventless ethanol fireplace per hour?

Accepted Answer

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.

Question 23

Are ethanol fireplaces safe for indoor use?

Accepted Answer

Yes, bioethanol fireplaces are safe for indoor use when operated responsibly. EcoSmart Fire's ethanol burners are certified to UL 1370 (developed through 100+ laboratory tests), EN 16647, and the ACCC Safety Mandate, covering North America, Europe, UK, and Australia. EcoSmart Fire holds more certified ethanol products than any other manufacturer in these markets. Clean combustion is the safety foundation: bioethanol produces only heat, water vapour, and trace CO₂, with zero carbon monoxide, smoke, or ash. For safe indoor operation, your space needs adequate ventilation (minimum 70–110 m³ [2,470–3,880 cu ft] depending on burner size), a smoke alarm on site, and a dry chemical fire extinguisher (AB:E or ABC rated).

Question 24

Are there any building code restrictions for ethanol fireplaces?

Accepted Answer

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.

Question 25

What is the heat output of a ventless ethanol fireplace?

Accepted Answer

EcoSmart Fire ventless ethanol fireplaces deliver heat output ranging from approximately 2.5 kW to 6 kW (8,500–20,433 BTU/h), depending on burner size. Heat output correlates directly to burner dimensions: smaller configurations produce around 2.5 kW and heat zones of approximately 20 m² [215 ft²], while the largest burners reach 6 kW and warm spaces up to 60 m² [645 ft²] or larger. Heat output is adjustable in real time via baffle inserts, so you are not locked at maximum output. You can dial flame intensity up or down to match your comfort needs. This matters for efficiency: over 90% of the heat generated stays in the room, as there is no flue to lose it through. Fuel consumption ranges from approximately 0.5 L/h on lower settings to 2+ L/h at full output, with operating costs around USD 1.50 per hour depending on burner size and flame setting. For sizing, minimum room volumes start at 40 m³ [1,413 ft³] for the smallest burners, scaling up to 116 m³ [4,097 ft³] for the largest. Match your space volume to burner size to ensure comfortable zone heating.

Question 26

What are the pros and cons of ventless fireplaces?

Accepted Answer

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.

Question 27

How do ethanol fireplaces work?

Accepted Answer

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.

Question 28

Can ventless fireplaces cause moisture problems?

Accepted Answer

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.

Question 29

How much heat does a bioethanol fireplace produce?

Accepted Answer

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.

Question 30

Do bioethanol fireplaces produce carbon monoxide?

Accepted Answer

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.
