Fireplace Inserts

Minimum footprints by range:

• Frame (surface-mounted, zero clearance): 746 mm x 798 mm, 403 mm deep
• Flex (recessed cavity): 488 mm wide x 730 mm tall, 365 mm deep
• Heritage (hearth alcove): 860 mm wide x 910 mm tall, 539 mm deep

Three zero-clearance bioethanol series, three distinct design intents. Flex is the format-flexible range for bespoke and commercial builds, Heritage reimagines the traditional hearth for compact and high-rise settings, and Frame delivers low-profile linear flame for contemporary and retrofit interiors.

Where they diverge:

• Flex offers the widest format choice: 12 single-sided sizes from 378 to 4,030 mm [14.9 to 158.7 in] viewing width, available across eight configurations (single-sided, left corner, right corner, bay, double-sided, peninsula, island, and bench). The viewing area is all live flame. Select models include an optional decorative box and copper log set. Single-sided models share a 365 mm [14.4 in] depth.
• Heritage is the single-sided traditionalist. Three sizes, 860 to 1,624 mm [33.9 to 63.9 in] wide, with the tallest proportions and deepest 539 mm [21.2 in] profile of the three. A SECC steel grate and toughened glass fire screen come standard, creating the classic log-fire read inside a modern firebox. Zero-clearance, ventless installation makes it suited to compact living spaces and high-rise buildings.
• Frame is the shallowest and lowest-slung, at 363 to 403 mm [14.3 to 15.9 in] deep and 598 mm [23.5 in] high. Five single-sided sizes, toughened low-iron glass for clearer flame, and a design that lets wall finishes be updated without disturbing the insert.

Flex for design freedom. Heritage for traditional proportions without the infrastructure. Frame for linear, low-profile statements and renovations.

No, ethanol fireplace inserts don't require a chimney. The clean-burning chemistry of bioethanol combustion produces only heat, water vapour, and minimal CO2, with no smoke, soot, or harmful gases that would need venting through a flue. This zero-clearance capability means the insert can sit inside your existing fireplace opening with heat retained in the room.

When retrofitting an existing fireplace with an active chimney, simply seal the damper or install a metal plate to block the opening. This prevents warm air escaping up the unused flue and maximises the fireplace's heating efficiency. All EcoSmart Fire bioethanol inserts are UL-listed and EN 16647 certified, meeting international safety standards for clean-burning, unvented operation.

Minimum room volume is determined by the burner capacity, not the fireplace footprint. EcoSmart Fire wall-mounted bioethanol fireplaces require between 40 m³ [1,413 ft³] and 90 m³ [3,178 ft³] depending on the model's heat output; compact models start at 40 m³, whilst larger designer series reach 90 m³. A few models in the largest range require up to 116 m³ [4,096 ft³].

These figures represent the air capacity needed to sustain clean combustion. EcoSmart Fire bioethanol fireplaces are engineered to operate safely in rooms of these volumes, meeting strict safety certifications. Natural air infiltration through doors, windows, and standard building construction provides adequate fresh-air exchange in rooms meeting the minimum volume.

The right fireplace scale often matches your room size naturally. A 40 m³ space (roughly 4 × 5 × 2 metres) suits compact models perfectly; a 90 m³ space (say, 6 × 5 × 3 metres) accommodates larger designer fireplaces. Rather than viewing this as a constraint, consider it a guide to matching the visual and thermal impact of the fireplace to the space itself.

Check your product's specifications for the exact minimum; the burner type determines the requirement, not the installation style.

Yes, EcoSmart Fire bioethanol fireplaces can be recessed into walls. The Flex range is specifically engineered for recessed installation, with the appliance mounted inside a wall cavity and finished flush with the surrounding surface, eliminating any protrusion.

A recessed Flex fireplace requires a framed cavity with specific dimensions: 365 mm [14.4 in] deep, 730 mm [28.7 in] high, and width from 488 mm [19.2 in] up to 4,140 mm [163 in] depending on the model chosen. The appliance slides into the cavity and anchors to the wall framing via mounting flanges. Crucially, any framing above the installation must be self-supporting; the fireplace itself carries no load from the structure.

The zero-clearance design means the unit installs directly against framing with no additional clearance requirements. Recessing integrates seamlessly with marble, timber, concrete, and bespoke millwork finishes, maximising the room footprint while creating a sculptural architectural focal point.

Recessed into an interior wall, a Flex bioethanol fireplace delivers a clean, indoor-optimised flame — no flue, no gas line, and no chimney required. The bioethanol fuel burns cleanly, producing no soot or smoke, making it well suited to sealed indoor environments where air quality and interior finish integrity matter. From living rooms and bedrooms to hospitality spaces, the flush, frameless installation creates a living indoor flame feature that is as architecturally refined as it is practically suited to indoor living.

Recessed installation of EcoSmart Fire bioethanol fireplaces follows a straightforward three-phase process.

Construct your wall cavity to the specified cut-out dimensions, slide the appliance into the opening so the base sits securely on 50 × 100 mm [2×4 in] framing, then secure it via the mounting hole flanges using a power drill and screwdriver. Remove the transport brackets, complete your wall panelling around the insert, and the fireplace is ready for operation: no venting, no gas line, no electrician required.

The absence of utility connections is what makes recessed installation possible in spaces where traditional fireplaces cannot go: interior feature walls, under-window niches, between built-in cabinetry.

Framing above the appliance must be self-supporting, and the toughened glass windscreen slides into place before the decorative charcoal spreads around the appliance tray. Most installations are completed within an hour.

EcoSmart Fire trade specialists are available to review your design drawings at no cost and provide technical support throughout installation. Compliance with UL 1370 and EN 16647 standards ensures your installation meets all relevant safety requirements.

The maximum width available in EcoSmart Fire wall-mounted fireplaces is approximately 4,232 mm [166.5 in], with a viewing area of approximately 4,031 mm [158.7 in], achieved in the Flex range's largest single-sided configuration. This makes it the widest wall-mounted option in the EcoSmart Fire portfolio.

The Flex range spans 12 sizes, starting from approximately 457 mm [18 in], giving you flexibility to scale from compact living spaces to dramatic feature walls. The Heritage range offers three compact sizes up to approximately 1,422 mm [56 in], suited to apartments and smaller interiors. The Frame range provides four size options within the 600–1,500 mm series for architectural installations.

Because EcoSmart Fire fireplaces use bioethanol fuel, they require no flue or chimney. This ventless design eliminates the structural constraints that limit traditional fireplaces, enabling you to specify truly expansive widths without engineering challenges. All sizes are engineered as zero-clearance, true built-in constructions and meet international safety standards including UL 1370, EN 16647, and ACCC certification.

Bioethanol fireplace inserts are designed as supplemental heat sources rather than primary heating systems for whole homes. EcoSmart Fire's zero-clearance inserts effectively heat individual rooms ranging from 35 to 65 square metres [377 to 700 square feet], depending on burner configuration and room volume. This focused heating strategy is intentional: inserts deliver 90 per cent efficiency because ventless design retains all heat within the room, rather than losing it up a chimney.

For whole-home heating, consider two approaches: combine multiple inserts in key gathering spaces (living areas, gathering spaces), or use your existing central heating system with inserts adding warmth and ambience to high-use zones. A single insert won't replace your primary heat source, but it reduces energy demand in the room it occupies whilst delivering the aesthetic benefits of real flame. This targeted approach suits luxury residential design where thoughtful zone heating aligns with sustainable living principles.

EcoSmart Fire wall-mounted fireplaces are engineered for integration into most wall constructions, though the backing material and clearances matter. Suitable substrates include brick, stone, plastered masonry, fire-rated plasterboard, tile, and concrete. Stud walls work when lined with fire-rated plasterboard and hollow-wall anchors; fabric and wallpaper directly behind the unit must be avoided.

Recessed installations require non-combustible cavity backing, such as vermiculite board, fibre cement, or steel framing lined with fire board, to maintain safe operating temperatures. The Flex Series is purpose-built for architect-led recessed integration and uses specified mounting brackets and spacers to create the necessary air gap for heat distribution.

Installation details vary by model, so the manufacturer's installation manual governs clearances to combustibles and any structural considerations.

Yes, EcoSmart Fire fireplace inserts are safe to use when installed correctly and operated according to manufacturer guidelines. Inserts are engineered with zero-clearance construction, with combustion containment built directly into the frame, and carry certifications across major markets: UL-listed to UL 1370 (USA), EN 16647 certified (Europe/UK), and compliant with Australian safety mandates.

Every component is engineered for safety. Burners are Grade 304 stainless steel. Glass is toughened, low-iron, and withstands heat exposure. A dedicated filling point, safe shut-off mechanism, and safety markings eliminate handling risk. The combustion system burns cleanly, producing heat, water vapour, and carbon dioxide; each output is managed safely within the minimum room volume requirements for each configuration.

Proper operation requires attention to ventilation. Each model has a minimum room volume requirement (ranging from 40 to 345 m³ depending on configuration) to ensure adequate oxygen and prevent indoor air quality concerns. Installation should follow the trade guidance provided, and the burner tray is mandatory for indoor use. The design reflects 20+ years of research and third-party safety validation. Professional installation is recommended to confirm correct placement and ventilation setup, ensuring reliable performance.
