EOS Hercules & Stone

EOS Hercules & Stone – Power in its most beautiful form

Authentic warmth. Architectural presence.
The EOS Herkules represents uncompromising sauna passion – a freestanding sauna heater that perfectly balances performance and aesthetics. With its clean lines and solid design, it's not just a reliable heat source, but also an architectural statement in your sauna.

Two variants – one goal: infusion culture at the highest level.
The compact S25 model, with its 25 kg stone volume, offers intense heat in a limited space – perfect for stylish private cabins. Those seeking the full infusion experience should opt for the S60: With an impressive 60 kg stone mass, it generates long-lasting, gentle heat and creates the ideal basis for robust infusions with plenty of steam and character.

Clear in design. Strong in expression.
Whether in subtle gray, deep black, or as an expressive stone version with a textured surface, each version blends harmoniously into high-quality sauna landscapes. The Herkules always remains in the background yet at the same time the focal point – a heater that makes an impact without being loud.

Warmth with attitude.
For those who expect more than just heat: The EOS Herkules is made for people who seek the real thing – in form, function and feel.
