MAJUS sauna and SANARIUM® heater

90°C in only 20 minutes

Thanks to the patented Turboheat function of the MAJUS heater, the sauna reaches 90 °C in just 20 minutes.

MAJUS sauna heater

Thanks to the new design, the Marius heater has a capacity of 60kgs of Finnish olivine stones which provide longer heat storage and an intensive infusion. This mirrors the output of heaters with a significantly higher stone volume.

VDE-tested quality

In combination with the 21029 sauna control unit, the SaunaPUR® function is then also possible, offering a unique sauna experience. This heater impresses not only with its appearance and technology, but also with its multiple functions. Furthermore, it meets all of the safety standards required for the VDE mark.


With the patented Turboheat function of our MAJUS sauna heater, a temperature of 90 °C takes only 20 minutes to achieve. This not only saves time for a spontaneous sauna session – it also saves energy. Thanks to its innovative air guidance, the MAJUS can let the heated air flow directly into the cabin when the Turboheat flap is open, heating it up without delay.
