Description

Cozy Heat's SW-TW represents a refined approach to wood-fired sauna heating, engineered in Estonia where sauna tradition runs deep. The through-wall configuration eliminates the need to transport firewood indoors, streamlining your sauna experience. Built with precision, this stove features a reinforced 5mm stainless steel flame cutter—the component bearing the greatest thermal and mechanical stress—ensuring exceptional longevity and reliability. Wood-burning heaters deliver a gentle, sustained warmth ideal for traditional stone-ladling steam sessions. The SW-TW combines performance-driven design with the authentic character of wood-fired heating.
