IKI-Kiuas

What IKI-Kiuas does

IKI-Kiuas Oy is a Finnish manufacturer of premium sauna heaters and wood-burning stoves, founded in 1997 and headquartered in Helsinki, with production operations in Pieksämäki. The company pioneered the open-structure mesh frame sauna stove in the mid-1990s, an architecture that allows free air circulation around a large stone mass to produce the characteristic Finnish 'löyly' steam. Core products include the Original IKI wood-burning stove (tested at 0.10% CO emissions, 9x below the EU EN 15821:2010 limit), electric heaters across the Pillar, Monolith, Corner, Wall, and Float designer lines, electronic control units including the UKU Glass Black Wi-Fi, and accessories. The brand name 'IKI' means 'forever' in Finnish and reflects the handcrafted stainless-steel construction performed by factory staff with over 40 years of welding experience.

IKI operates a hardware-sales business model distributing premium-priced sauna heaters through an authorized global distributor network covering Europe, Japan, Australia, and North America, alongside direct sales from its Helsinki showroom. Customer segments span private homeowners seeking premium residential sauna experiences, commercial spas and hotels requiring high-capacity heating solutions, communal and public facilities, and specialty hospitality (e.g., sauna cruise ships). Pricing is not publicly disclosed; sales are conducted at unit-based pricing via distributors or by appointment at the Helsinki showroom. The company has positioned itself for the connected era through a partnership with HUUM OÜ (Estonia) for the UKU Wi-Fi control unit and co-designed IKI mobile app, and has invested in designer collaborations (Eero Aarnio for the Float line, dSign Vertti Kivi & Co. for the Monolith) and an official partnership with the Santa Claus Foundation for brand authenticity.
