Description

The Harvia Linear 18 Compact with water tank (WKLI18CPTM) combines traditional wood-fired sauna heating with a compact, space-saving design and added everyday practicality. With a nominal power output of 18 kW, this stove is designed for sauna rooms of approximately 8 to 18 mยณ, making it suitable for medium-sized garden and indoor saunas.

The compact steel body is finished in elegant black and features a durable cast-iron door with a glass window, allowing the firelight to enhance the sauna atmosphere. Optimised combustion channels and controlled airflow ensure efficient burning, fast heat-up times and a clean, stable flame.

A key feature of the WKLI18CPTM is the integrated stainless steel water tank, which is heated automatically while the sauna is in use. This provides a convenient supply of hot water for washing or cleaning without requiring additional energy sources, making it especially practical for off-grid or garden sauna installations.

Despite its compact footprint, the stove accommodates up to 40 kg of sauna stones, ensuring strong heat retention and soft, even steam during infusions. The reduced depth compared to the standard Linear 18 makes this model ideal for saunas with limited space while maintaining full performance.

Whether for a private home sauna or a compact outdoor sauna setup, the Harvia Linear 18 Compact with water tank delivers reliability, efficiency and the authentic experience of a traditional Finnish wood-burning sauna.
