Helo Vienna STS Electric Sauna Heater is a sleek and versatile wall-mounted heater designed for modern home saunas. Perfect for small to medium-sized saunas (3–12m³), it combines style, efficiency, and advanced technology for a premium sauna experience. Its compact design frees up space while providing powerful heating for an enjoyable sauna session.
Featuring integrated controls and a 9-hour timer, the Vienna STS model allows easy operation and precise temperature management. Its adjustable stone capacity of 12–20 kg ensures flexible steam generation: fewer stones heat up the sauna faster, while more stones create soft, enveloping steam. Vulcanite sauna stones (<10cm) are recommended for optimal performance.
The heater incorporates Helo-WT Water Technology, offering three sauna experiences:
-
Gentle Sauna (50–60°C): Enveloping steam for longer sessions, ideal for bio-aroma or salt saunas.
-
Flexi-Sauna (60–80°C): Moderate humidity at lower temperature, suitable for bio-aroma or salt saunas.
-
Hot Sauna (80–100°C): Intense heat with low humidity for a traditional sauna experience.
Available in Grey, Black, or Chrome, this heater combines premium craftsmanship with smart functionality. Handcrafted in Hanko, Finland, Helo products represent over 100 years of sauna expertise, providing the authentic Nordic sauna experience in your home.
