Aito AK-68 ST – heat-storing sauna heater with an external firebox, designed for large saunas and convenient use. Firing takes place from another room, so cleanliness and more space are maintained in the sauna.
The large stone capacity allows a large amount of heat to be accumulated, which is released gradually, creating stable and long-lasting steam. This is an ideal solution for both home and commercial saunas.
