Dual-Room Sauna Heating with Fireplace Ambiance and External Feed Convenience
The Harvia Pro 20 DUO WKPR20DUOS wood-burning sauna heater combines powerful sauna heating with the warmth and atmosphere of a fireplace. Designed with an external feed system and wall-embedded glass hatch, this heater allows the sauna to be heated from an adjacent room while creating a visible fireplace effect outside the sauna space.
Built for medium-sized saunas, the Pro 20 DUO delivers fast heat-up performance and rich steam generation through its generous stone capacity. Adding firewood and removing ash from outside the sauna keeps the sauna area cleaner while creating greater flexibility for interior layouts. Finished with a stainless steel exterior and adjustable feet, the heater provides both durability and installation convenience.
Designed to expand functionality and maximize sauna design freedom, the Pro 20 DUO combines traditional wood-burning performance with practical dual-room operation.
