HUUM CLIFF 9 kW 240V Electric Sauna Heater- Complete Package Options

Unmatched Heat and Lasting Steam

The CLIFF electric sauna heater offers unparalleled performance, reaching temperatures up to 230°F, the highest available in North America. While many other sauna heaters are limited to 194°F due to UL listings, the CLIFF heater’s design allows it to effortlessly achieve and maintain higher temperatures, providing an authentic and intense sauna experience.

Beyond just heat, the CLIFF heater maximizes the use of sauna stones by minimizing metal components, ensuring that most of the heat is radiated by the stones, not the metal. This process enhances the release of beneficial negative ions, which are commonly found in traditional wood-heated saunas. Combined with the large number of stones, the CLIFF heater creates soothing, curative steam that lasts longer, giving you a relaxing and rejuvenating sauna experience every time.

Efficient and Eco-Friendly Design withNordic Inspiration

The CLIFF electric sauna heater stands out with its stunning natural stone surface, echoing the rugged beauty of Nordic cliffs. Its eye-catching appearance is paired with an environmentally conscious design, as the body is made from stainless steel cutouts leftover from the production of STEEL heaters, reducing metal waste. The heater’s slim shape and small safety distances make it perfect for smaller sauna rooms. An internal air tunnel boosts heating efficiency by 25%, prolonging the life of the heating elements. With ample sauna stones, the CLIFF heater offers gentle, long-lasting steam, creating the ideal relaxing sauna experience.
