The Harvia Pro 36 Duo is a powerful wood-burning sauna heater designed for large sauna rooms up to 1,271 cu. ft., offering intense heat and rich steam in a short time. Its design allows you to load firewood and enjoy the glow of the fire from an adjacent room, creating the ambiance of a fireplace while keeping the sauna space clean and uncluttered.

With a generous stone capacity, the Pro 36 Duo delivers strong, consistent steam for demanding sauna sessions. The durable stainless-steel outer casing and steel-framed glass door combine long-lasting performance with a refined, professional look. Adjustable feet simplify installation and help align the chimney opening precisely, and the heater can be paired with a separately sold chimney-mounted water tank for convenient water heating.

Engineered in Finland, the Harvia Pro 36 Duo is an ideal choice for those seeking powerful wood-fired performance, flexible installation, and the comfort of heating two spaces with one heater.
