Product information
Robust and reliable for high-temperature biomass and wood-fired systems
The DW ECO 2.0 is Jeremias UK’s most versatile twin-wall insulated chimney system, engineered to meet the demanding requirements of solid fuel and biomass combustion in commercial and industrial environments. With a temperature resistance of up to 600 °C and certified G-class soot fire resistance, it is the ideal solution for installations where safety, durability, and thermal performance are critical.
Its double-wall stainless steel construction, filled with high-density rock wool insulation, ensures excellent heat retention and protection of surrounding structures. The system’s modular push-fit connection with locking band allows for fast, secure installation and easy maintenance access.
