The Harvia WHP1000M Chimney Extension is designed to extend the height of sauna chimney systems for wood-burning stoves, ensuring proper ventilation and draft performance. Constructed from black powder-coated steel, it is built to withstand high temperatures and environmental exposure in both indoor and outdoor installations.
Its engineered joint and locking groove system securely connects with compatible chimney components, helping prevent unwanted movement caused by thermal expansion. This enhances system stability and long-term reliability.
With a 1000mm (39.3") length and 220mm diameter, the extension integrates seamlessly into Harvia chimney systems, making it suitable for a range of sauna configurations requiring additional chimney height.
This component is intended for use as part of a complete chimney system and should be installed according to manufacturer guidelines.
