DYNAMIC PLUS Fireplace inserts with MAMMOTH accumulation rings

This accumulation system uses patented cast iron rings designed for direct contact with hot flue gases—no transition components required. The high thermal conductivity of cast iron and the heat accumulation capacity of the special MAMMOTH compound ensure efficient heat transfer. A cast iron spiral embedded inside each ring distributes heat evenly and deep into the material, securing stable thermal storage even under frequent use. Mechanical joints between the rings are strong yet allow for easy assembly and servicing. Each ring weighs 38 kg, has a height of 80 mm, and a bulk density of 4.5 kg/l. The final ring in the system can be directly connected to a flue pipe or elbow. Thanks to a firing temperature exceeding 1000 °C, the system remains odor-free—even during the initial burn-in. Altogether, the DYNAMIC PLUS with MAMMOTH rings delivers a reliable, long-lasting heat accumulation solution without compromising on design or performance.
