EOS Herkules XL S50 Vapor


EOS Herkules XL S50 models have a unique design featuring an innovative construction with two separate rock stores.

Two 25 kg large rock stores provide a perfect balance between strong air convection and optimal heat storage capacity.

This ensures an optimized air convection and allows to make water splashes alternately on the left or on the right side for more steam and more sauna enjoyment.

The 'Vapor' version is based on the EOS Herkules XL S50 model and features a built-in evaporator which is located right between the rock stores which provides this sauna heater its unique appearance. An elegant cup holder for essences or herbs perfectly complements the design and enhances the possibilities. Use a sauna as a traditional Finnish sauna, as a mild steamy bath or a herbal bath.

Also available with high-quality matt black finish*

Optional: Heater guard rail with mounting brackets.
