FAQ's
What is the heat output of a ventless ethanol fireplace?
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.
How does a ventless ethanol fireplace work?
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.
How much does bioethanol fuel cost?
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.
Can ethanol fireplaces be used outdoors?
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.
Can I refill my bioethanol fireplace while it's running?
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.
How long will my ethanol fireplace burn?
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.
What gases and emissions does a bioethanol fireplace produce?
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
Are bioethanol fireplaces safe for homes with children or pets?
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.
Are ventless ethanol fireplaces different from ventless gas fireplaces?
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.
Do bioethanol fireplaces produce carbon monoxide?
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.
