Harvia Linear 22 Sauna Heater Package

This package is designed for small- to medium-sized, traditional wood-burning saunas. It provides steady, efficient heat for rooms between 353 – 777 ft³ (10 – 22 m³). If unsure, use our sauna heater size calculator to calculate your room size.

The WHP1500 / WHP1500M Chimney Kit is a UL-listed system that fits all Harvia wood-burning stoves with a 4.5" (115 mm) flue outlet. It’s suitable for indoor or outdoor use and installs through the ceiling or wall (wall thimble required for side exits). The included smoke pipe and 59" chimney section together reach about 9–10 ft total height, ideal for standard sauna ceilings.

The WL110 Floor Plate provides a non-combustible, heat-safe base under the stove.

Together, they form a complete, ready-to-install system from stove to roof.
