Aito AK-47 – traditional heat-storing sauna heater, designed for genuine, gentle and long-lasting steam. It is a classic Finnish sauna solution, allowing you to enjoy the sauna for a long time after firing.
A large stone mass heats up to a high temperature, and then the heater gradually releases heat, creating a „soft“, oxygen-rich steam that does not tire and allows you to stay in the sauna longer.
