Versatile combination of electric sauna heater and steamer, offering spa experiences for large saunas.
Choose between a traditional Finnish sauna, steam sauna, herb sauna, or aromatic sauna.

Thanks to its sturdy construction, heating elements divided into two circuits, and easy serviceability, the Virta Pro heater is an excellent choice for heavy usage.
If a heating element needs replacing, it can be done quickly and easily as the entire heating element deck can be pulled out from the heater.
All maintenance activities have been taken into account in the design of the heaters from the start.
Water Tank: 10 Liters (automatically refilled from a nearby water connection point)
Minimum Sauna Height: 210 cm
Operating Voltage (3-phase): 400 V 3N~
Steamer Output: 4 kW (5 kg/h steam generation rate)
Suitable Stone Size: 10–15 cm in diameter

Use only split-face stones designed for sauna heaters. Suitable materials include peridotite, olivine diabase, and olivine.

Note: The use of ceramic “stones” or soft soapstone is strictly forbidden, as they do not retain enough heat and may cause the heating elements to break.

Placing the Sauna Stones: Rinse stone dust off before stacking. Do not drop stones onto the stone grate. Stack stones loosely to ensure proper airflow through the heater. Do not build a high pile of stones on top of the heater.
