Description

Cozy Heat Thru-Wall Wood-Burning Sauna Stove

The Cozy Heat Thru-Wall Sauna Heater brings authentic Nordic sauna tradition to your sauna while offering a unique and convenient installation design. Hand-crafted in Estonia, where sauna bathing is a way of life, this wood-burning sauna stove produces gentle, long-lasting heat and luxurious steam when water is poured over heated sauna stones.

What makes the Cozy Heat TW model special is its through-the-wall design, allowing you to load firewood from outside the sauna room. This keeps the sauna interior cleaner while maintaining the traditional wood-fired sauna experience.

Designed with durability and efficiency in mind, this stove features a 5mm thick stainless steel flame cutter, extremely clean combustion technology, and fuel efficiency that uses 25–40% less firewood than comparable sauna heaters.

Whether you are installing a backyard sauna, outdoor sauna cabin, or indoor traditional sauna, the Cozy Heat TW stove delivers authentic wood-fired sauna performance with modern engineering.
