Q: Are ventless fireplaces safe?

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 1

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 2

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 3

Do bioethanol fireplaces produce carbon monoxide?

Accepted Answer

No, bioethanol fireplaces do not produce carbon monoxide when operating correctly. EcoSmart Fire's bioethanol burners produce only heat, steam, and a small amount of carbon dioxide during combustion. This clean-burning characteristic eliminates the need for flues or chimneys, as there are no harmful emissions requiring extraction. However, proper ventilation remains essential for optimal air quality and safety.

Question 4

Are ventless fireplaces safe?

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 5

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 6

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 7

Do ethanol fireplaces require professional installation?

Accepted Answer

No, EcoSmart Fire ethanol fireplaces don't require professional installation for most homeowners and builders. Freestanding units need no tools beyond included accessories; built-in models require only basic hand tools (power drill, screwdriver, level) and a non-combustible framing structure that's self-supporting.

Most installations complete in under an hour to a day, depending on whether you're placing a freestanding unit on a level surface or custom-framing a built-in model. Zero-clearance construction eliminates the structural complexity of traditional fireplaces, with no chimney engineering, no gas line coordination, and no specialist trades required.

If you're converting from an existing gas fireplace, arrange professional gas disconnection before installation begins. This is a straightforward, one-time safety step completed by a qualified technician.

For complex custom cabinetry, load-bearing integrations, or commercial projects, engaging a builder familiar with fireproof materials ensures optimal results and code compliance across jurisdictions. The EcoSmart Fire installation guides and instructional videos included with every purchase walk you through the process step by step.

Question 8

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 9

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.

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 10

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 11

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 12

How long does it take to assemble an ethanol fireplace?

Accepted Answer

Setting up an EcoSmart Fire bioethanol fireplace is quick and straightforward, with timelines varying by product type. Freestanding fireplaces require the least time: simply unpack and position them in your desired location. No tools or assembly. This takes minutes. Insert models, including the Flex range, involve basic assembly of the firebox and burner frame. The Flex Single Sided, for example, includes ten assembly steps: frame construction, mounting, burner placement, glass panel installation, windscreen, and media arrangement. With basic hand tools (power drill, screwdriver, level), most people complete this work in 30 to 45 minutes. Fire Pit Kits follow a similar pattern. The six core assembly steps (frame assembly, burner installation, connections, ignition test, fuel fill, and safety verification) typically take 45 minutes to an hour for someone working with basic tools. Heritage and Grate models, designed to retrofit into existing traditional fireplace openings, skip frame assembly entirely: unpack and insert into the opening. The longest part of any installation is usually not the appliance assembly itself, but preparing the installation space. Selecting placement, confirming clearance compliance with your model's safety requirements, and finishing any surrounding cabinetry or surrounds are the variable factors.

Question 13

Are ethanol fireplaces safe for indoor use?

Accepted Answer

Yes, ethanol fireplaces are safe for indoor use when installed to manufacturer guidelines and used in properly ventilated spaces. They're engineered with multiple safety layers: spill-proof fuel systems, flame arresters in fuel bottles, and automatic shut-off lids that extinguish flames when closed. EcoSmart Fire's products have passed over 100 laboratory tests simulating real-world scenarios and meet UL 1370 (North America), EN16647 (Europe), and ISO 17873 international safety standards. Complete combustion produces only water vapour and a small amount of carbon dioxide (CO₂) — equivalent to approximately two burning candles. There's no smoke, soot, or ash to compromise indoor air quality. Unlike wood or gas fireplaces, ethanol burners require no chimney, flue, or gas line, which eliminates an entire category of installation risks. Ventilation is straightforward: adequate air exchange must occur during operation, but natural room air infiltration through windows, doors, and standard building ventilation is sufficient for most indoor environments. EcoSmart Fire provides specific room-volume guidance (typically 40–116 m³) to help you verify your space meets requirements. The absence of combustion byproducts like carbon monoxide means ventilation functions purely to maintain oxygen supply, not to exhaust dangerous gases. This is fundamentally different from traditional fireplaces. Safety is built into both the product and how you operate it. Follow fuel handling instructions, use only approved e-NRG bioethanol fuel, maintain adequate room volume, and verify your space meets ventilation guidelines before installation. When these conditions are met, indoor ethanol fireplaces deliver clean flame with the peace of mind of engineered reliability.

Question 14

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 15

What is bioethanol fuel made from?

Accepted Answer

e-NRG bioethanol is produced from renewable plant sugars, primarily corn and sugarcane grown in dedicated energy crops, through multi-stage fermentation and distillation. The fermentation process converts plant sugars into ethanol, which is then distilled to achieve premium purity levels of 96–97% ethanol by volume. This purity is essential: it exceeds the azeotrope limit of 95.6%, enabling complete combustion, a stable flame, and extended burn duration. A small amount of water and denaturants (methanol or Bitrex) is retained for safety and regulatory compliance. e-NRG's distillation process ensures superior thermal efficiency of 90–95%, compared to 75–85% for lower-grade alternatives. Each production batch is tested for purity, moisture content, and specific gravity with full traceability at every stage, guaranteeing consistency and quality. Because bioethanol comes from renewable crops, the fuel completes a closed-loop carbon cycle: CO₂ released during combustion is reabsorbed by growing crops, creating a carbon-neutral energy source. This renewable, plant-based origin is what makes e-NRG bioethanol a genuinely sustainable choice for premium bioethanol fireplaces.

Question 16

Can ethanol fireplaces be used as primary heat sources?

Accepted Answer

Ethanol fireplaces work best as supplemental heat sources paired with existing climate control, rather than as primary heating for your home. EcoSmart Fire bioethanol burners deliver genuine warmth. The XL900, for example, produces 4 kW (15,000 BTU/h) of thermal output, and because the fireplace is ventless with closed combustion, every BTU stays in the room rather than escaping through a flue. This makes them ideal for extending your entertaining season, reducing heating demand in a gathering space, or replacing a traditional fireplace entirely. You'll get real warmth and flame without installing gas lines, venting, or structural modifications. Pair it with your existing heating system for full-home comfort, and use the fireplace to create warm focal points in spaces you want to enjoy more, such as a sitting room or outdoor entertaining area.

Question 17

Can I convert my existing fireplace to bioethanol?

Accepted Answer

Yes, you can convert your existing fireplace to bioethanol using purpose-built conversion products from EcoSmart Fire. The conversion is straightforward and requires no structural modifications to your fireplace opening. Fireplace Grate models sit directly on a level surface inside your existing fireplace and come in different sizes to fit various opening dimensions. These use durable stainless-steel burners and feature adjustable flame control. Heritage Grate models feature traditional cast-iron aesthetics with ceramic fire-rated logs, ideal if you want a wood-fired appearance without the soot and ash. VB2 Burner is a compact stainless-steel burner specifically designed for Edwardian, Federation, Art Deco, and Art Nouveau style fireplaces, where it instals with adjustable feet and no modifications needed. The conversion itself takes minutes: position the grate or burner into your fireplace, ensure it's level, and fill with bioethanol fuel. The essential step is ensuring any existing gas connections are professionally disconnected and made safe first. This is a critical safety requirement. EcoSmart Fire has completed over 150,000 installations globally since launching in 2004, demonstrating the reliability of these conversion systems. Because bioethanol fireplaces are ventless and need no chimney or gas supply, conversion becomes genuinely simple compared to traditional alternatives.

Question 18

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 19

Will my ethanol fireplace heat the room?

Accepted Answer

Yes, ethanol fireplaces do heat your room, and the amount of warmth depends entirely on how well your space matches the burner you choose. Because the ventless design keeps all combustion heat inside rather than sending it up a flue, you get genuine radiant warmth, not just visual flame. The practical variables that determine how effective the heat will be in your room are: the size of your room and ceiling height (a small burner in a large, high-ceilinged space will produce less noticeable warmth), insulation quality (poor insulation means heat escapes faster), how enclosed or open the space is (heating an open-plan room is harder than a defined room with doors), and ambient conditions when you're using it (a room already at 15°C will feel colder than one at 18°C even at the same flame setting). You can adjust heat output by controlling the fuel fill level or using baffle inserts: lower fuel means gentler warmth over a longer burn, higher fuel creates stronger heat. If you're working with a specific room, check the minimum room volume requirement for your chosen burner to ensure adequate oxygen exchange through natural ventilation.

Question 20

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 21

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.
