Aito AK-47 ST – a heat-storing sauna heater with an external firebox, designed for the most comfortable sauna experience. The firing takes place from another room, so cleanliness, more space, and peace remain in the sauna.
This heater stores heat and allows you to enjoy gentle steam long after firing – one firing ensures sauna pleasure for the whole evening.
