Aito AK-78 – a high-power heat-retaining sauna heater, designed for larger saunas and longer use. Thanks to its large stone capacity, this heater stores a lot of heat and allows you to enjoy gentle, even steam long after firing.
The heat is released gradually, so a stable temperature is maintained in the sauna without sudden fluctuations. It is the ideal choice for those who value long sauna procedures and comfortable, non-tiring steam.
