Frequently Asked Questions
How do I choose between the Cozy 12 kW and 18 kW models?
The Cozy 12 kW is designed for sauna rooms from about 210 to 423 cubic feet and uses at least 265 pounds of stones. The Cozy 18 kW is sized for larger rooms from about 317 to 635 cubic feet and uses at least 353 pounds of stones. If your sauna is bigger, has more glass or tile, or is in a colder climate, the 18 kW model is usually the better choice.
How many stones do I need and what type is best?
The Cozy 12 requires at least 265 pounds of sauna stones and the Cozy 18 requires at least 353 pounds. Use natural sauna stones such as olivine or peridotite in the 10 to 15 cm range. Avoid river rocks or decorative stones, since they can crack or shatter when heated. Many installers order an extra box so they can choose the best shapes for airflow and fit.
How efficient is the Cozy wood-burning sauna stove?
Cozy wood-fired sauna stoves are engineered for high combustion efficiency. They are designed to use approximately 25 to 40 percent less firewood than many comparable wood stoves while producing cleaner exhaust gases. This efficiency helps reduce fuel costs and supports more environmentally conscious sauna bathing.
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 usually heats larger rooms more quickly because of its higher output and larger firebox.
Does the Cozy stove require a chimney?
Yes. A certified wood-burning chimney system is required. Use flue pipe and chimney components that are rated for wood-burning sauna stoves and that meet local building and fire codes. Professional installation is strongly recommended for safety and performance.
Do I need professional installation?
Professional installation is highly recommended. A qualified installer will configure the chimney, verify clearances to combustibles, and ensure the stove complies with local building and fire safety requirements for wood-burning appliances.
