Twin Wall Flue

Build a quality insulated chimney with our insulated stainless steel chimneys AISI 304.

The insulated chimneys offered by BalkanEnergy.NET are twin wall stainless steel flues with laser welding, ending in a male and female part. Ceramic fibers with a density of 92 kg / m3 were used as insulation material for the chimney bodies. The assembly of stainless steel chimneys is extremely precise, eliminating the need for brackets or silicone seals. The operating temperature of our AISI 304 stainless steel chimneys is 400 ° C and the maximum temperature they can withstand is 1000 ° C. Chimneys with laser welding are manufactured in accordance with European and International standards and are used to remove flue gases, chemical and oxidizing gases from boilers  and stoves running on oil, gas, solid fuel and biomass.

Insulated stainless steel chimneys are a good alternative with prices competitive with the masonry chimney. They are most often used in the construction of external chimneys of buildings or for placing the chimney through areas that are easily flammable and insulation is mandatory. According to the location of the elements for building a chimney, our insulated stainless steel chimneys are divided into:

• Straight twin wall flues - Straight twin wall flues are insulated chimneys that are used to build the vertical part of the chimney. The standard length of straight insulated chimneys is 100 cm, but we also offer straight chimneys with a length of 50 cm, as well as telescopic insulated chimneys. When calculating the total length for your chimney 6cm should be removed from the final value because of the connections between the elements. For more precise heating systems we also offer insulated chimneys with built-in thermometer and inspection opening.
• Twin wall elbow flue - twin wall elbows are insulated chimneys that are used to change the direction of the chimney. According to the angle, the knees are divided into: knee 90 ° and knee 45 °. It is recommended not to use the elbows more than 3 times in one heating system, as this would make it difficult to remove the flue gases.
• Twin wall tee flue - the twin wall tee is an insulated chimney body that is used to build any outdoor chimney. Each tee contains a condensate cap with an opening through which condensate drains. The condensate tee cap is detachable, giving you direct access to clean your chimney. According to the angle of connection to the chimney, the tees are divided into two types: T tee and U tee.
