Aito AK-78 ST – heat-accumulating sauna heater with an external firebox, intended for convenient use and long heat retention. Firing from another room allows maintaining cleanliness and more space in the sauna.
Due to the large stone capacity, this stove ensures stable and long-lasting steam, so one firing is enough for long sauna use. It is an excellent choice for larger saunas and for those who value a true sauna experience.
