WADEX DWW IINVEST Insulated Chimney Liner 1000mm 150/200mm

The WADEX DWW IINVEST insulated chimney liner is a professional-grade double-wall stainless steel system engineered for the reliable and efficient extraction of flue gases. Measuring 1000mm in length with a diameter configuration of 150/200mm, this component is built to withstand demanding thermal conditions while maintaining structural integrity. Its robust construction makes it a dependable solution for both upgrading older chimney stacks and integrating into new heating system installations.

Advantages

The primary benefit of this insulated chimney liner lies in its high-quality stainless steel construction, which offers superior resistance to corrosion and high temperatures. The double-wall design incorporates effective thermal insulation, which helps maintain optimal flue gas temperatures, thereby improving draft efficiency and reducing the risk of condensation buildup within the chimney. This design ensures a safer operation of heating appliances and contributes to the longevity of the entire flue system.

Suitable for

• Modernization of existing masonry chimneys
• New installations for solid fuel, gas, or oil heating appliances
• Systems requiring high thermal resistance and efficient exhaust extraction

When it may not be suitable

This liner may not be suitable for applications involving highly aggressive chemical environments or specific industrial processes that exceed the maximum operating temperature of 450°C. It is also not intended for use in systems where the diameter specifications do not match the requirements of the connected heating appliance.

Key specifications

• Material: Stainless steel
• Length: 1000mm
• Inner diameter: 150mm
• Outer diameter: 200mm
• Operating temperature range: 1°C to 450°C

How to use

Installation should be performed by a qualified professional to ensure compliance with local building codes and safety regulations. The liner sections must be securely connected, ensuring that all joints are properly sealed to prevent flue gas leakage. It is essential to verify that the chimney structure can support the weight of the liner and that the necessary clearances from combustible materials are maintained according to the manufacturer's guidelines and local standards.

What to consider before purchase

• Verify the required diameter for your specific heating appliance
• Ensure the chimney shaft dimensions are compatible with the 200mm outer diameter
• Check local regulations regarding chimney liner materials and installation requirements

Usage recommendations

Regular inspection and maintenance by a certified chimney sweep are recommended to ensure the system remains free of soot and debris, maintaining peak performance and safety throughout the heating season.
