The DM44 - 180mm ID starter flue block is an essential component of the Isokern DM block system, which is celebrated for its double-module design. These blocks are constructed from pumice, a natural insulator, helping to maintain optimal flue gas temperatures while minimizing heat transfer to the outer casing. This dual-wall system not only promotes efficient heating but also reduces the risk of cracking, leaks, and stains.
The DM44 is quick and straightforward to install, making it a convenient choice for stoves, open fires, cookers, and inserts that burn wood, solid fuel, oil, or gas. However, it is not suitable for condensing appliances, including biomass and pellet stoves. Certified by HETAS and CE marked, the Isokern DM system ensures compliance with key industry standards, adding peace of mind to your purchase.
