DW-FU

The DW-FU is the classic among double-walled stainless steel chimneys. This versatile exhaust system is suitable for all appliances operating under negative pressure with oil, gas, or solid fuels. A 32.5 mm thick insulation made of high-temperature resistant, non-combustible mineral wool ensures stable flue performance regardless of weather conditions and minimizes the heating of the outer pipe at flue gas temperatures of up to 600°C. The high quality of the materials used, an extensive selection of components, numerous diameter and surface options, and quick and easy installation have made the DW-FU one of the best-selling chimney systems over the past decades.
