Compact through-the-wall sauna heater for 9-18 m³ saunas, designed for rich and soft steam, long-lasting heat and lower wood consumption.
We combined traditional sauna knowledge with modern engineering. The result is a heater that uses approximately 25% less wood than comparable sauna heaters — without any additional devices. In ideal test conditions, the saving reached up to 40%.
This efficiency and clean combustion have earned COZY the respected German BImSchV 2 certification, confirming that our sauna heaters meet strict environmental and emission standards.
