At the heart of the sauna is a cast-iron wood-burning stove. The cast-iron furnace compartment is completely covered with thick walls made of natural stone. Soft heat from the heated stones fills the sauna room, excluding hard thermal radiation from the furnace itself.
Inside the stove, in the upper part, where the maximum heat is accumulated, there is a special compartment closed on all sides for charging stones. There, stones can reach temperatures of over 650C, which provides conditions for the creation of lightweight microfine steam. By opening the door of this compartment and splashing water onto these stones, that same light steam will escape into the sauna and fill it, enveloping you in gentle warmth! The stove is so powerful that its stone charge cannot be drowned with water in a whole day, and it will produce first-class steam every time with a characteristic pop.
And YES! You can throw water on the rocks yourself!
