Fireplace inserts from Austroflamm – long-lasting, user-friendly and efficient
A fireplace insert from Austroflamm is noted for its exceptional quality and durability. Great care is taken when selecting the materials used to manufacture our stoves. By implementing rigorous quality control measures, we guarantee that you will enjoy your Austroflamm fireplace insert for many years to come.
A fireplace with self-closing door
The self-closing stove door seals the firebox securely and efficiently. At the same time, the closing mechanism of the firebox door ensures that the combustion chamber remains airtight. That’s why this Austroflamm heating insert is suitable for use as a stove for room-sealed operation.
Simple control of the heat output
A single lever controls the supply of combustion air, regulating both the primary and secondary air flows. While the primary air stokes the fire from below – particularly during the start-up phase – the secondary air is preheated via air ducts within the stove and fed into the firebox from above.
Airwash for a clean viewing window
The preheated secondary air is used for what is known as the airwash system, which keeps the viewing window clean. This way, you can enjoy the wonderful play of flames from your Austroflamm heating fireplace without any obstruction.
Connecting the fireplace to the chimney
The fireplace can be connected to the flue at the top or to the side, depending on the installation situation. There is also a connection for supplying combustion air to the combustion chamber from outside. As a result, this Austroflamm fireplace insert is certified and approved as a fireplace for room-sealed operation.
Performance and efficiency level of the fireplace insert
Boasting a nominal heat output of 12 kW, the 75x51 SII 2.0 fireplace insert is suitable for heating rooms with a volume of between 218 and 343 m³. The firebox lining, made from Austroflamm’s patented Keramott, which is heat-resistant up to 1200°C, combines with the sophisticated combustion air flow system to ensure high combustion temperatures, thereby guaranteeing outstanding heat output and a high efficiency level of 81% for the fireplace insert.
Inset fire that meets all testing and certification requirements
A wood-burning stove from Austroflamm falls below the currently valid emission limit values and is issued with all the certification required for operating a wood-burning heating appliance.
