National Flues has designed this product for homeowners who demand safety, performance, and reliability. In this comprehensive guide, we will detail every aspect of the cowl, from its design to the ease of installation, so you can make an informed decision.
Overview
The TWPro MB Rotating Cowl is engineered to serve solid fuel and gas/oil appliances, including woodstoves, coal effect fires, oil boilers, and gas boilers. Its innovative rotating cover aids in managing down drafts by equalising the outlet velocity, ensuring that your chimney performs optimally even during severe weather conditions.

Key Features & Benefits
- Durability and Safety: The use of premium 304 and 316L stainless steel provides excellent resistance to heat and corrosion. This means that the cowl will maintain its integrity over time, even when exposed to harsh weather or high temperatures. HETAS approval and CE marking further underscore its commitment to safety standards.
- Efficient Down Draft Management: The rotating cover is a standout feature. By spinning in the wind, it helps balance the chimney’s air stream and prevents the build-up of harmful downdrafts. This not only improves the performance of your heating appliance but also contributes to energy efficiency.
- Versatile Fuel Compatibility: Whether you choose wood, oil, gas or low sulphur coal, the TWPro MB Rotating Cowl is designed to work with a range of fuels. This versatility ensures that you enjoy consistent performance, regardless of your fuel source.
- Simple and Secure Installation: The cowl is designed with ease of installation in mind. It comes with a locking band that provides a secure connection between the twin-wall insulated chimney sections. Maintaining the prescribed clearance of 50mm to combustible materials is straightforward when following the comprehensive installation instructions provided.
Installation Insights
Installing a chimney cowl might seem daunting, but the TWPro MB Rotating Cowl simplifies the process considerably. Begin by ensuring that all safety guidelines are met. The cowl should be mounted so it maintains a 50mm distance from any combustible materials. Once this clearance is confirmed, carefully align the cowl with the existing chimney structure. Using the supplied locking band, secure the twin-wall chimney sections together. If you are unsure of any steps, National Flues recommends consulting a professional installer to ensure the installation is performed safely and competently.
