Sähkökiuas

A sähkökiuas, often translated as an electric sauna heater, is a common type of heater used in Finnish saunas. It utilizes electricity to generate heat, warming the sauna stones and the air within the sauna room. Unlike traditional wood-burning saunas, electric heaters offer convenience and precise temperature control.

The basic operation of a sähkökiuas involves heating elements, typically made of resistance wire, which glow red-hot when electricity passes through them. These elements are surrounded by a large number of sauna stones, usually peridotite or olivine, which absorb and store the heat. When water is ladled onto the hot stones, it creates steam (löyly), which raises the humidity and temperature of the sauna.

Sähkökiuas models vary in size and power output, designed to suit different sauna room dimensions and the desired heating time. They often come with integrated controls for setting the temperature and timer. Safety features are paramount, including overheat protection and ensuring adequate ventilation around the unit. The installation requires proper electrical wiring and adherence to safety codes. The popularity of sähkökiuas stems from their ease of use, cleanliness, and consistent heat output, making them a practical choice for many modern sauna users.
