The DM36 150mm ID x 150mm high offset block from Isokern is part of their high-quality DM (Double Module) block system. This sophisticated chimney system effectively maintains flue gas temperatures while minimizing heat transfer to the outer casing. The clever separation of inner and outer components accommodates thermal movement, significantly reducing cracking risks.

Constructed from naturally insulating pumice, the DM36 ensures rapid heating of your appliance and sustained warmth, enhancing its performance and reducing condensation and soot build-up. Available in outer casing sizes DM36, DM44, and DM54, it is versatile for various heating applications, including stoves, open fires, inserts, and cookers burning wood, solid fuel, oil, or gas (excluding condensing appliances like Biomass and Pellets). HETAS approved and CE marked, the DM36 stands as a testament to high safety and quality standards.
