With two open sides, Flex Double Sided fireplace insert creates the perfect room divider. The see-through design provides unobstructed views of the flickering flame from the front and the back, infusing warmth and ambiance into two adjacent rooms.
With an EcoSmart Flex 104DB.BX1, you have design freedom with the choice of a Decorative Box on the left or right-hand side. Both designs are fitted with a glass panel that divides the box and the Firebox and creates an attractive streamlined look. Instantly transform any wall into a feature, indoors or out, with a stylish, clean-lined Flex Firebox.
One of the longest flames available in the Flex Series is created by using 2 of our ever-popular XL900 burners. With an overall heating capacity of 120m2 this appliance is best suited to large open spaces – think hotel lobby, large open plan restaurants.
Each burner holds 9L of fuel, and can deliver a stunning flame for up to 13 hours.
