From classic ambience to contemporary clean burning

Bioethanol represents the discerning homeowner’s vision: fire without compromise. Gone are the days of stacked logs and persistent soot. With this innovative fuel, your evenings fill with a subtle, flicker-lit glow and the peace of mind that comes from knowing you’re making a sophisticated, sustainable choice. The result is more than just warmth; it’s an elevated experience that centres comfort, ease, and style.

Aesthetic, environmental, and lifestyle enhancements

Aesthetic: Minimalistic grate inserts amplify a room’s architecture without overwhelming its design, letting your personal style take centre stage.
Environmental: Bioethanol is derived from renewable sources, producing only heat, water vapour, and trace CO₂ - no smoke, no hazardous particles.
Lifestyle: Enjoy the freedom of ventless operation - no need for a flue or gas line, just pure design flexibility.

The rise of ventless fireplace technology

How ventless operation simplifies fireplace conversion

Traditional fireplaces demand complex installations - chimneys, ducts, and heavy renovations. The new approach? Drop-in installation. Modern, ventless fireplaces are self-contained; you simply place the insert into the existing cavity and enjoy instant transformation. This seamless adaptation is especially attractive for those who treasure both heritage details and contemporary convenience.

Benefits: no flue, chimney, or gas connections

Drop-in installation: Minimises disruption and preserves architectural features.
Design freedom: Place a ventless insert anywhere - from stately lounges to alfresco dining spaces.
Weather-resistant: Many models are built for both indoor and covered outdoor enjoyment, turning patios into four-season retreats.

Harmonising design flexibility with air quality

Without the need to vent combustion byproducts, air quality in living spaces improves. According to third-party studies, bioethanol fires release only trace amounts of carbon dioxide and water vapour - preserving the purity of your indoor environment. For those living in urban environments or properties with design limitations, the convenience and safety are unmatched.

The science of clean burning

How bioethanol fuels a ventless fireplace

Premium e-NRG Bioethanol fuel powers the clean and efficient operation of these fireplaces - emitting negligible pollutants. It’s a renewable liquid fuel made from plant byproducts, delivering robust flames without the residue or odour associated with wood burning.

Comfort and efficiency

EcoSmart Fire grate inserts deliver between 3.4kW and 6kW (11,430 - 20,433BTU/h), offering ample warmth for cosy evenings or lively gatherings. This range goes well above the typical 2.5 - 5kW (8,500 - 17,000BTU/h) comparison, meaning you experience genuine comfort even in larger living rooms or open-plan spaces.

Environmental impact and responsible living

Bioethanol delivers a carbon-neutral flame, as the CO₂ released during combustion is offset by the plants used in production. With no toxic byproducts or ash, there’s less cleaning and no need for chimney sweeping - helping homeowners live beautifully, responsibly, and with less environmental impact.

What to expect: installation and care

Delivery and Setup: Grates arrive ready for placement, with installation typically completed within an hour.
Daily Use: Refuelling and lighting take mere minutes; burners often run for up to 8 hours on a single fill (5L/1.3gal).
Maintenance: Simply wipe down surfaces and ensure the burner is dry between uses.
Aesthetics: Customisable accessories, such as glass fire screens and decorative media, let you personalise your hearth.

Comparing emissions: bioethanol vs. wood

Fuel Type	Particulate Emissions	CO₂ Output (approx.)	Odour	Ash/Residue
Wood	High	75g/hr	Moderate	High
Bioethanol	Negligible	10g/hr	Low	None
