Product Description

Wood Sauna Heating with Integrated 30L Water Tank and Traditional Sauna Comfort

The Harvia Pro 20 LS WKPR20LSM wood-burning sauna heater combines dependable heating performance with the convenience of an integrated side-mounted water tank. Designed as a practical solution for cottage and off-grid sauna environments, this heater warms both the sauna and water simultaneously for a more efficient and comfortable sauna experience.

Featuring a spacious 30-liter water tank positioned on the left side of the heater, the system utilizes generated stove heat to warm water while heating the sauna room. The graphite black exterior, stainless steel front components, and cast-iron glass hatch combine durability with a traditional atmosphere enhanced by the visible glow of the fire.

Designed with optimized combustion channels, adjustable feet, and optional accessory compatibility, the Pro 20 LS delivers efficient operation with added functionality.

A wood-burning heater involves more than choosing a stove. Chimney routing, room volume, clearances, stones, protective surfaces and the surrounding sauna design all matter. If one part of the setup is unclear, send us the question before ordering.
