Optimize the flue gas evacuation of your heating system with the 150 mm x 50 cm Double Wall Stainless Steel Flue Pipe (Reference: B25142411 ), an essential component designed to guarantee maximum safety, efficiency, and durability in pellet stoves, fireplaces, and biomass boilers. This high-quality flue is specifically manufactured to withstand high temperatures and demanding conditions, ensuring optimal gas venting performance and preventing the accumulation of condensate and soot.

Thanks to its ingenious double-walled design, this pipe offers superior thermal insulation. The inner layer of high-strength stainless steel facilitates a smooth and unobstructed flow of flue gases, while the intermediate air chamber or insulation and the outer wall protect adjacent structures from extreme heat. This not only improves chimney draft and stove combustion but also drastically reduces the risk of fire and optimizes fuel consumption.

This 50 cm long, 150 mm diameter duct is versatile and perfectly suited for both straight vertical runs and horizontal installations. Its metallic finish provides a clean, professional look, ideal for exposed installations. Investing in certified quality exhaust components is essential to extend the lifespan of your heating system and ensure clean, safe air in your home or office.

Frequently Asked Questions about Stainless Steel Flue Pipes

What type of stoves is this 150mm pipe compatible with?

This pipe is primarily designed for pellet stoves, traditional fireplaces, and biomass boilers that require a 150 mm outlet diameter. It is important to verify the outlet diameter of your heating appliance before purchasing to ensure a proper connection.

Why choose a double-walled pipe instead of a single-walled one?

Double-walled pipes offer superior thermal insulation. They maintain the temperature of the gases inside to ensure optimal draft and prevent condensation, while also reducing the external temperature of the pipe, protecting nearby walls and ceilings from potential heat damage.

Can this section be installed on the exterior of the house?

Yes, thanks to its stainless steel construction and double-walled design, this duct perfectly withstands inclement weather, making it suitable for sections running along the exterior of facades or roofs.

How is the joining between sections carried out?

The system features a tongue-and-groove coupling designed to fit securely and firmly with other components of the same diameter. It is recommended to use joining clamps to ensure a watertight seal and structural support for the assembly.
