The 950 Magnum Firechest with Damper is part of our premium Isokern range, designed for efficient and safe heating solutions. This firechest, supplied as a convenient flat pack, is easily constructed to form a precise and preformed fire opening ready for your personalised finishing. The Magnum variant allows you to create expansive fire openings up to 1.2 meters wide.
Made from pumice, a natural insulator, this firechest offers superior thermal efficiency. The insulating properties of pumice help your chimney flue gases reach optimal temperatures quickly, enhancing the performance of your heating appliance shortly after ignition. This feature also ensures the chimney remains warmer for longer periods, reducing the chances of condensation and soot build-up.
Endorsed by HETAS and CE marked, the Isokern Double Module (DM) System Chimney is a reliable choice for any home.
