for your interior
Upgrade your open fireplace – no renovation required
Thanks to our patented solution, enjoy a vibrant, authentic flame while significantly improving the energy efficiency of your fireplace.
With the Open Insert, there’s no longer any need to choose between the beauty of the fire and performance.
80% less pollution
yourself
in France
the Open Insert re-burns smoke during wood combustion.
This process reduces pollutants, improves combustion efficiency,
and ensures better heat distribution.
4 times more heat
80% less pollution
Turn your fireplace into an efficient, eco-friendly source of heat, effortlessly.
Thanks to its double-combustion system, the open insert delivers four times more heat while reducing pollutant emissions by 80%.
This innovative solution boosts efficiency from just 10% in a traditional fireplace to 45% with the open insert.
Easy to install
yourself
Our open insert fits seamlessly into your fireplace, with no construction work and no connections required. Simply slide it into the hearth. Watch our video to see just how easy it is to install.
Thanks to the double-combustion system, smoke is burned a second time, significantly lowering its temperature as it rises through the flue. As a result, a flue liner is not required, except in specific cases such as a damaged chimney or non-compliant fire safety clearances. If your open fireplace is in good working condition, flue lining is therefore not necessary.
Custom-made
in France
Based on the dimensions of your fireplace, choose the model that best suits your needs from the four open insert bases in our range. The outer casing is then custom-cut to ensure a perfect fit within your fireplace.
Have a corner fireplace or a specific configuration? We adapt the open insert to your existing fireplace. Each open insert is carefully crafted in our workshop, located in the heart of the Alps, ensuring a high-quality, made-to-measure product.
Patented open insert
The open insert operates through natural convection. The fire heats refractory stainless-steel tubes, drawing in ambient air from the front of the unit. As this air circulates through the tubes, it warms up, passes behind a stainless-steel plate, and is released through discreet slots. This very hot air reheats the smoke, triggering a second combustion by reigniting it. This patented system enables double combustion in an open fireplace and significantly improves the performance of an existing fireplace. The open insert has also been awarded the Lépine Competition prize and the Observeur Design label.
