EOS Watermill sauna set with 34.GM HD heater

floor-standing, heavy-duty

Spectacular Watermill system for luxury class themed saunas.

Ideal for very intensive, demanding commercial operation.

The Watermill sauna brings “action” and a unique water splash experience in every sauna cabin. The spectacular Watermill wheel with drive and control mechanism (with auto-filling system) is perfectly completed with the impressive 34.GM HD sauna heater with a massive granite front panel.

The Watermill wheel rotates slowly counter-clockwise, which already makes it an attraction in the sauna. After an automatic signal it starts to rotate in the other direction, so that the scoops take some water from the basin under the wheel and pour it directly into the cascade mounted over the heater, causing powerful and spectacular steam shock effects. A very large stone volume of the sauna heater ensures at the same time high energy reserves and water evaporation capability.

Design hint: in combination with our coloured light or sound effects, the water splashes may be turned into a spectacular ceremony and a unique experience for all sauna guests.

Includes automatic water refilling device FWA01. Permanent water connection required.
