About
Discover our collection of premium Cozy Heat wood-burning sauna heaters, handcrafted in Estonia with a 5mm stainless steel flame cutter for lasting durability and exceptional combustion efficiency. Choose from in-sauna models (OG) in 12kW and 18kW capacities, or thru-wall designs (O TW, OG TW) that let you load wood from outside the sauna entirely — plus higher-capacity SW and Quattro Thru-Wall options for larger builds. Each heater delivers authentic, high-temperature löyly steam, meeting Germany's EN 15821:2010 emissions standard.
