A sauna heater is a device used to warm the air in a sauna, creating a relaxing and therapeutic environment. These heaters can be electric, wood-burning, or gas-powered, with electric heaters being the most common due to their ease of use and consistent heat output. They are designed to reach high temperatures, typically between 150°F and 195°F (65°C to 90°C), which helps promote sweating and relaxation. Sauna heaters often come with controls that allow users to adjust the temperature and duration of the heating session. Some models also include features like timers and safety shut-off mechanisms. Proper maintenance of a sauna heater is essential for safety and efficiency, ensuring a pleasant experience for users.
