The DM54 545mm Square Casing x 300mm High is a part of the Isokern DM block system, a premium choice for System Chimneys. This double module (DM) system is designed to ensure efficient and safe performance. The double wall construction keeps flue gas temperatures stable while preventing heat transfer to the outer casing, which helps avert cracking and leaks. Built from natural pumice, an excellent insulator, this chimney system heats up quickly and retains warmth effectively, minimizing condensation and soot build-up. The DM54 is available in three sizes – DM36, DM44, and DM54, and is compatible with wood, solid fuel, oil, and gas (excluding condensing appliances like Biomass & Pellets). Approved by HETAS and CE marked, the DM54 offers reliable, high-performance chimney solutions. For installation, please refer to our detailed guides.
