Bi-O Sauna Heaters

The temperatures in the Bi-O sauna are lower than in the classic dry (Finnish) sauna, usually around 45 - 60° C with a humidity of around 40 - 55 %. The Bi-O sauna is considered to be more gentle on the circulation and is often combined with the addition of essential oils or special lighting (light therapy). The length of the humid sauna session with approx. 15 - 30 minutes is longer than in a regular dry sauna – otherwise the procedure is the same.

The integrated vaporizer of EOS Bi-O type sauna heaters leakes the steam out next to the sauna stones so that it is spread quickly in the entire cabin. An integrated bowl allows to place oils and sauna essences to make your sauna an aromatically exhilarating experience for the senses.

All EOS Bi-O sauna heaters have water shortage detection and dry-run protection. The excellent air convection of the EOS heaters ensures optimal air circulation in the cabin and thus creates a pleasant sauna climate, which can be adjusted very flexibly – from hot and dry to mild and humid.

With a power range of 3.0 to 30.0 kW, they are perfect for saunas with a volume between 3 and 65 m³. Of course, all Bi-O heaters can also be used as classic dry Finnish heaters if required, thus offering maximum flexibility and versatility.
