Schiedel Dual is a multifunctional chimney system for all types of fuel. It enables flue gas removal from solid fuel, oil and gas boilers, including condensing boilers.
The dual-draft chimney system Dual consists of smooth and profiled ceramic pipes, which are placed in a common block of expanded clay concrete with a density of 1150 kg / m 3 and a minimum compressive strength of 3 MPa.
The smoke duct is a smooth insert placed in the smoke duct; characterized by thermal resistance. The insert has a density of 2100 kg / m 3 and a minimum compressive strength of 25 MPa. The flue gas channel is profiled thin-walled pipes 66 cm long located in the air-flue gas duct; they are characterized by tightness, good compressive strength and resistance to aggressive condensate, while maintaining low weight.
