IMPRESSION Fireplace inserts with MAMMOTH accumulation rings

These cast-iron rings are installed directly in the flue path, enabling gradual release of accumulated heat even after the fire has gone out. A patented cast-iron spiral inside each ring ensures even heat distribution throughout the thermal storage mass and withstands repeated thermal stress. The joints between the rings are robust yet easy to disassemble, allowing for straightforward installation and maintenance. Each ring weighs 38 kg, stands 80 mm tall, and has a bulk density of 4.5 kg/l. The final ring can be directly connected to a flue pipe or elbow. MAMMOTH significantly enhances the insert’s heat accumulation capability, elevating the IMPRESSION series to a new level of performance and comfort.
