The Cozy 12 SW is an Estonian-engineered powerhouse designed for those who prioritize massive steam production and fuel efficiency over the rapid, dry heat of typical budget stoves. It is particularly famous for its massive stone capacity and eco-friendly combustion.

The Cozy 12 SW is a premium wood-burning heater defined by its sleek cylindrical shape and high-volume stone cage. Unlike many heaters that rely on radiant heat from the metal body, the Cozy 12 is designed to be "wrapped" in stones. This creates a more moderate, long-lasting heat and allows for a truly "bracing" steam experience when water is tossed on the rocks.

Engineered to meet the strict German BImSchV certification, it is one of the cleanest-burning wood stoves on the market, emitting smoke gases up to 6x cleaner than standard heaters. Its high efficiency means you use roughly 25–40% less firewood to achieve the same temperature as competing models.

Key Features & Comparison

The "Löyly" Specialist: With a stone capacity of 265 lbs (compared to the Harvia M3's 66 lbs), this stove holds heat much longer and produces a much softer, more humid steam.

Eco-Efficient: The three-stage combustion system ensures the wood burns completely, reducing ash and emissions while saving you money on fuel.

Superior Durability: The flame cutter (the part most prone to burning out) is made of 5 mm thick stainless steel, significantly extending the lifespan of the unit.

Flexible Layouts: While the "SW" is the standard floor mount, it is often sold as a Through-Wall (TW) variant, allowing you to feed the fire from an adjacent room to keep the sauna clean.
