Single-Wall Stainless Steel Chimney for Modernization or New Installation

The single-wall stainless steel chimney is ideal as a connecting line from the chimney to the boiler, for flue renovation in masonry chimneys, or for installation in lightweight chimneys. The installation of single-wall exhaust systems improves the draft in the chimney and meets the requirements for the operation of modern heating systems. The annular gap between the single-wall stainless steel pipe and the chimney wall can also be used for air supply.

Typically installed indoors, single-wall flue pipes are both condensate- and gas-tight and can withstand flue gas temperatures of up to 600°C and pressures of up to 5000 Pa, depending on the system. The single-wall stainless steel chimneys and the EW-PPS and EW-PP FLEX systems made from polypropylene are manufactured from high-quality materials and have CE certification.

Jeremias exhaust systems are made from high-quality stainless steel and come with a manufacturer’s warranty of up to 25 years. Single-wall exhaust systems are ideal for a variety of applications, especially as connecting lines or for chimney renovation.
