Cozy Heat Thru-Wall Sauna Heater and Sauna Stones
Cozy Heat Thru-Wall Sauna Heater and Sauna Stones
The Cozy Heat Thru-Wall Sauna Heater is a traditional wood burning sauna stove designed to bring authentic sauna bathing to your home. Hand made in Estonia, where sauna culture is deeply rooted in everyday life, this heater produces the gentle, long lasting warmth that defines a classic wood fired sauna experience.
Wood burning sauna stoves provide a softer and more natural heat compared to electric heaters. As the sauna stones heat up, pouring water over them produces rich steam that fills the room and creates the relaxing atmosphere sauna bathing is known for.
The Cozy Heat TW features a practical through wall design that allows firewood to be loaded from outside the sauna room. This keeps the sauna interior clean and organized while still delivering the traditional warmth and ambiance of a wood fired heater.
Constructed from durable steel, the stove is designed for reliability and longevity. The most demanding component of the heater, the flame cutter, is made from thick 5 mm stainless steel to withstand intense heat and repeated heating cycles.
Cozy sauna heaters are also engineered for efficiency and cleaner combustion. Their advanced design produces smoke gases that are up to six times cleaner and reduces firewood consumption by approximately 25 to 40 percent compared to many traditional sauna stoves.
The Cozy Heat Thru-Wall Sauna Heater is available in two heating capacities to accommodate a variety of sauna sizes. The 12kW model is suitable for sauna rooms between 210 and 423 cubic feet, while the 18kW model is designed for larger sauna spaces ranging from 317 to 635 cubic feet.
Each heater package includes genuine Cozy Heat sauna stones made from olivine diabase, a dense natural stone known for excellent heat retention and consistent steam production. These stones are available in Traditional Split Face Stones or Premium Rounded Stones so you can choose the steam style and appearance that best fits your sauna.
The correct stone mass is essential for proper sauna heating performance. The 12kW heater requires a minimum of 200 pounds of sauna stones, while the 18kW heater requires at least 310 pounds of stones. Because natural stones vary in size and shape, this listing includes options with additional stone boxes. The extra box allows you to select stones that fit best within the heater cage, improving airflow, heat distribution, and overall sauna performance.
