The Adjustable Pipe 250-350mm Ø 175 features exceptional engineering that meets the demands of modern heating systems. Designed specifically for solid fuel, gas, and oil appliances, it integrates seamlessly into your chimney or flue system to provide effective exhaust and maintain optimal performance. The high-quality stainless steel construction ensures long-term durability while withstanding high temperatures and harsh environmental conditions.
Key Benefits and Features
• Adjustability: Unlike fixed flue pipes, the adjustable length feature (from 250mm to 350mm) allows for a tailored fit to any installation scenario. This flexibility is invaluable for professionals who often encounter unique site conditions.
• Premium Materials: Constructed with an inner layer of 316L stainless steel and an outer layer of 304 stainless steel, both with a thickness of 0.40mm, this pipe exemplifies strength and reliability. The corrosion resistance provided by these materials ensures that your system remains robust and efficient over time.
• Superior Insulation: The compressed rockwool insulation, with a density of 200kg/m³, not only enhances heat retention but also provides a thermal cushion between the high-temperature flue gases and the surrounding combustibles, thereby ensuring safety.
• Secure Installation: The innovative locking band system removes the need for screws, simplifying the installation process and minimising the risk of errors. This system ensures that the pipe sections are securely connected, promoting overall system stability.
• Safety Approvals: With HETAS approval and CE marking, the pipe meets stringent EN1856-1 standards (EN1856-1 T600 N1 W V2 L50040 G50 and EN1856-1 T200 W V2 L50040 O20), providing assurance of its safe performance under regulated conditions.
Addressing Common Concerns
Installation Ease: One of the most frequently asked questions is about the ease of installation. The design of the Adjustable Pipe 250-350mm Ø 175 specifically addresses this concern through its locking band system. Professionals appreciate the simplicity and time-efficiency it brings. For those undertaking self-installation, clear guidelines and a safety margin of 50mm from combustibles protect both property and life.
Durability and Longevity: Some customers worry about the longevity of flue components. The use of high-grade stainless steel, known for its resistance to corrosion and extreme temperatures, ensures that your investment will stand the test of time. This means fewer repairs and a reliable performance, season after season.
Thermal Efficiency: Maintaining an efficient heating system is not solely about reducing energy waste; it is also about safety. The excellent insulation provided by compressed rockwool significantly improves thermal efficiency by retaining heat where it is needed, thereby reducing the risk of hazardous overheating near combustible surfaces.
Compatibility: The versatility of the Adjustable Pipe 250-350mm Ø 175 is another major advantage. Whether you are using a woodstove, a gas appliance, or an oil boiler, this component is designed to provide an optimal connection. Its adaptability ensures that it can be integrated into almost any traditional or modern heating arrangement, bringing a seamless and functional finish to your project.
Installation Recommendations
Before installation, always double-check the measurements and ensure that the adjustable pipe is cut and fitted to the precise length required. Ensure that all components are handled with care to avoid damaging the polished stainless steel surfaces. Remember, while the locking band system is designed for ease, taking the time to properly secure each joint will ultimately enhance the safety and effectiveness of your heating system. It is advisable to consult relevant EN1856-1 guidelines and local regulatory requirements to confirm that all installation practices meet the necessary safety standards.
Enhancing Your System with Optional Accessories
For those seeking to further improve their chimney or flue installation, consider exploring optional accessories. Accessories such as additional insulation wraps, specialised flue cowlings, or custom mounting brackets can offer enhanced functionality and an even more customisable setup.
