Why Choose EcoSmart Flex?

Modular Flexibility
Available in single-sided, double-sided, bay, peninsula, or island configurations, the Flex Range accommodates virtually any floorplan or design vision. Each model features a zero-clearance firebox, making installation in timber-framed structures fast and hassle-free.
No Flue, No Fuss
Because the Flex Range is fuelled by clean-burning bioethanol, there’s no need for gas lines, electrical hookups, or chimneys. That means you can incorporate a luxury fireplace in places previously impossible – from penthouses to hotel lobbies, kitchens to bedrooms.
ZERO Clearance
Install direct into a timber frame as the firebox provides all of the thermal protection required. Plasterboard to the bottom and sides, with an A1 board up the breast above, finish off with a metal beed and you are ready to go. Leave a 250mm clearance above and you can have a recessed TV, or use a shelf to deflect the heat.
Luxury Meets Safety
Every EcoSmart Flex firebox includes toughened glass screens and precision-engineered stainless steel construction. The fires are tested to global safety standards and supported by the industry-leading EcoSmart Fire burner technology.

Clean, Green, and Maintenance-Free

As with all EcoSmart products, the Flex Range is powered by e-NRG bioethanol fuel, which is plant-based and burns without smoke, soot, or ash. Learn more about why bioethanol is the cleaner, safer fuel of the future on our Bioethanol Explained page.
