Frequently Asked Questions
What is the difference between the Cozy O 12 kW and 18 kW models?
The Cozy O 12 heats rooms from about 210 to 423 cubic feet and requires at least 265 pounds of stones. The Cozy O 18 heats larger rooms from about 317 to 635 cubic feet and requires at least 353 pounds. Choose the model based on room size, insulation, and climate.
What type of stones should I use?
Use natural sauna stones such as olivine or peridotite in the 10 to 15 cm size range. Do not use river rocks or decorative stones. Proper sauna stones store heat efficiently and create smoother, more comfortable steam.
How long does it take to heat the sauna?
Most saunas reach bathing temperature in about 45 to 75 minutes depending on room size, insulation, stone loading, and wood quality. The 18 kW model often heats larger rooms more quickly.
Does the Cozy O require a chimney?
Yes. A certified wood-burning chimney system is required for safe operation. Always follow local building and fire codes. Professional installation is strongly recommended.
Do I need professional installation?
Professional installation is recommended to ensure proper chimney setup, correct clearances, and compliance with fire and building codes.
