DW-ECO 2.0
Double-walled stainless steel chimney
The cost-effective alternative to the classic DW-FU is our DW-ECO 2.0 system, a double-walled stainless steel flue gas system for all regulated heating systems operated with oil, gas, or solid fuels in negative pressure operation and flue gas temperatures up to 600°C. It is suitable for both dry and wet operation. A continuous insulation shell made of 25mm high-quality, dense mineral wool with a guaranteed compressive density of 120 kg/m³ prevents thermal bridges between the inner and outer pipes, ensuring consistent chimney draft and minimal heating of the outer pipe.
