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 water splashes 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 XL is ideal for intensive commercial operations of the Finnish sauna. Extra-large rock store with up to 100 kg volume - optimal for powerful water splashes. The height of the heater may be adjusted +/- 15 cm.
