Fireplace Inserts

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.

EcoSmart Fire bioethanol fireplace inserts cost significantly less to install than traditional gas or wood-burning fireplaces because they eliminate structural modifications, gas line installation, and chimney work. Installation focuses on securing the insert in a framework and finishing the surround, a zero-clearance design that removes expensive building work.

The cost advantage comes from simplicity: no venting requirement, no electrical wiring, no combustion air ducts. Installation typically completes in under an hour once the framework is ready, keeping labour costs lower and timelines shorter. Many homeowners invest in professional finishing work, but the fireplace insert itself requires minimal specialist input.

EcoSmart Fire reports up to 70% in cost savings compared to gas fireplaces across the full installation journey. This includes the insert and surrounding build work. The remaining costs reflect design choices: cabinetry finishes, materials, and architectural integration, decisions that would apply regardless of fireplace type.

Once installed, running costs are minimal. A 9-litre fuel refill burns for 8–13 hours depending on heat setting, making it one of the most economical focal point options. Total cost of ownership, including installation and fuel, typically proves competitive with traditional alternatives.

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.

EcoSmart’s fireplace inserts are mostly used for new construction when an entirely new fireplace is desired for a given space. They are not designed for the conversion or remodelling of an existing masonry or gas fireplace but could be used if the dimensions align.

To convert an existing fireplace we recommend using our fireplace grates or ethanol burners as noted above.

Ensure that the flue has been closed off and the relevant suppliers have officially detached all connections to utilities.

Yes, ethanol fireplace inserts are straightforward to install compared to traditional fireplaces. Unlike wood-burning or gas fireplaces, there's no flue, gas line, or electricity connection required, which eliminates most of the structural and trade complexity. The zero-clearance technology means the appliance mounts directly against standard timber framing without additional wall spacing, giving you genuine flexibility in placement.

The installation typically follows three phases: build the framework to the specified opening dimensions, slide the appliance into the cavity and secure with standard screws, then complete your wall panelling and finishes. Single-sided inserts follow a 10-step sequence, from framework construction through media positioning, while fire pit kits simplify to 6 steps. Basic tools suffice: a power drill, screwdriver, and level. Models range from 25.7 kg [56.5 lbs] to 222.1 kg [488.6 lbs], and heavier units benefit from a second pair of hands, though no specialist trades or custom engineering is needed.

Flexibility is where ethanol fireplace inserts stand apart. Zero-clearance installation removes traditional constraints, so you can incorporate the fireplace at any renovation stage: before wall lining, mid-construction, or even as a retrofit into existing openings. Your finishing materials (marble, timber, concrete, or custom millwork) can be chosen independently, and the appliance fits into interior walls, under cabinetry, or recessed niches. After installation, fill with e-NRG bioethanol, ensure adequate room ventilation, and test the ignition.

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

EcoSmart Fire bioethanol fireplaces feature true zero-clearance design. At the back and sides, the appliance frame installs directly into wood or metal stud walls with no spacing required between the unit and surrounding combustible materials.

For mantels and surrounds fitted above or beside the unit, specific vertical clearance distances apply. These differ depending on whether the material is combustible or non-combustible; your model's support page provides the exact dimensions and diagrams for your configuration.

Each model specifies a minimum room volume for adequate ventilation. This is an air quality requirement rather than a physical clearance distance. Your product specifications or installer will confirm the threshold for your room.

Before installation, verify your wall cavity dimensions against the product's cut-out specifications to ensure tolerances align.

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.

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.
