Cozy Heat OG Sauna Stove

Cozy Heat OG Sauna Stove

The Cozy Heat OG is a wood-burning sauna stove handmade in Estonia, combining traditional wood-fired heating with a distinctive trilateral design characterized by clean lines and curved surfaces. Available in 12 kW and 18 kW configurations, the OG is designed for sauna rooms ranging from 210 to 635 cubic feet, depending on the selected model. The open-stone construction provides substantial stone capacity for traditional sauna use, while the steel body incorporates a glass-front heater door, ash box, cleaning access, and a heavy-duty 5 mm thick stainless steel flame cutter. Cozy states that its combustion technology can reduce firewood consumption by 25–40% compared with comparable sauna stoves while supporting lower-emission combustion. The OG operates entirely with wood fuel and does not require an electric sauna heater control. Required sauna stones are sold separately. Additional chimney/flue and site-specific installation components may be required.
