EOS Invisio series

underbench sauna heaters

Special sauna heater for concealed installations under the sauna benches.

EOS Invisio is a special range of the unique concealed “underbench” sauna heaters, which are installed under the sauna benches with a partition wall with only a 10 cm gap to the main sauna wall.

Thanks to their construction and particular installation, EOS Invisio heaters offer high safety standards and save a lot of valuable space in the cabin. There is no more risk of accidentally touching the heater, and your sauna will look more spacious inside.

In spite of the hidden installation, traditional sauna infusions are of course still possible. All EOS Invisio heaters include a stainless steel water funnel with a silicone tube. The special gutter inside the heater spreads the water over the entire heater width to ensure quick evaporation.

The EOS Invisio series is ideal for private and commercial operations of the Finnish sauna. XL-version with up to 75 kg stone volume - optimal for powerful sauna infusions. The height of the heater may be adjusted.

Thanks to an optional vaporizer (2,0 kW / 3,0 kW), Invisio can also be used as Bi-O version for humid sauna operation. Retrofitting possible on site.
