A stylish chimney solution
Extend Your Chimney with Style and Confidence
The Harvia WHP500M Steel Chimney Extension 500mm Black is manufactured from high-quality stainless steel and provides an easy, reliable way to extend your Harvia steel chimney system while maintaining its premium appearance and structural integrity.
Harvia's innovative joint mechanism allows chimney extensions and supplementary components to connect securely by twisting together. Once installed, the smoke pipes are locked firmly in place using integrated grooves, preventing movement caused by temperature changes during heating and cooling cycles. This engineered connection enhances both stability and long-term reliability.
Designed specifically for Harvia steel chimney systems, the extension provides a seamless continuation of the chimney while maintaining the clean, modern appearance of the original installation.
For installation flexibility, the chimney system can be installed indoors to a height of 3 metres without additional support, while the maximum self-supported outdoor installation height is 2 metres.
