Commercial Twin Wall Flue Our DW-ECO Twin Wall Flue Systems are German manufactured, engineered in both Spain and in Germany.

The high-temperature resistant twin-wall system they produce is made from 304 outer (0.4-0.6mm) and 316 inner (0.4-0.6mm) stainless steel. The twin-wall system is densely packed with rigid mineral wool insulation, of 25mm thickness (120kg/m3) designed to maintain the heat inside the system and create a better draw.

DW ECO 2.0 is a multi fuel, twin wall insulated stainless steel flue system suitable for all applications in negative and positive pressure, including condensing (joint seals).

Designed for use with all gas, oil, pellet, wood, coal domestic, commercial or industrial appliances.

Maximum constant working temperature 600° C and short firing up to 700° C with thermal shock testing up to 1000° C.

Size Range Available in 250mm (10”) - 500mm (20”). Any larger sizes can be ordered in up to 600mm internal diameter.

Please note: all sizes are based on the internal measurement of the flue. The external size will be 2” bigger than the internal measurement.

Installation Guidelines For detailed installation guidelines, please refer to the following: • DW-ECO 2.0, Certification & Installing Instructions

• NACS- National Association of Chimney Sweeps

• Document J UK Building Regulations

• Planning Office

• HETAS -Heating Equipment Testing and Approval Scheme 3

ONE SYSTEM MULTIPLE APPLICATIONS All of the twin-wall system have a stainless steel finish. However, these can be powder coated to most BS or RAL colour codes if required.

Standard floor standing Boiler:

DW ECO 2.0 is the solution for small commercial and industrial standard natural draft or pressure jet boilers.

DW ECO 2.0 is suitable for wet conditions, with a capillary break in every joint. Depending on the kind of fuel and sulphur content alternative inner wall stainless steel alloys are available under request.

Please consult first your national installation guidances and regulations before ordering.

CE Designation: T400 N1 V2-L50040 O30

Condensing boilers in cascade:

DW ECO 2.0 can be installed to fit modern condensing appliances in cascade. using high quality silicone joints in every component DW ECO 2.0 can hold positive pressure till 200 pa. a slope of 3° minimum is compulsory in horizontal runs, therefore the use of Tees and elbows in 87° is needed.

The use of drain points in the most critical parts of the installation is recommended. The special designed header tees are neccessary when connecting multiple appliances into a common Header, these are fully welded and guarantee the water resistance of the installation. Please read our technical manual and installing instructions or contact our technical department for installation advise.

CE Designation: T200 P1 W V2-L50040 O00

Biomass Boiler:

A typical application for the chimney system DW ECO 2.0 are biomass boilers. Heating with biomass a CO2 neutral alternative for individual houses, apartments or office buildings DW ECO 2.0 gives the solution for the smoke exhaust. DW ECO 2.0 is tested to 600° C continous operating temperature and soot fire tested at 1000° C and has the highest corrosion resistance level V3.

Please note that frequent cleaning and maintenance of the chimney system (specially with solid fuel) will extend the lifetime of the product. Jeremias provides a 25 year warranty.
