HUUM CLIFF MINI 3.5kw Electric Sauna Heater(123-212cf)
HUUM CLIFF Mini Electric Sauna Heater
Experience the perfect blend of design, efficiency, and environmentally conscious innovation with the HUUM CLIFF Mini Electric Sauna Heater. Designed and crafted in Estonia, this elegant wall-mounted heater is engineered to bring spa-level performance to compact home saunas. Its slim profile, fast heat-up time, and soft, consistent steam make it a favorite among modern sauna enthusiasts.
Designed for Small Saunas, Built for Big Impact
The CLIFF Mini is ideal for saunas between 123 and 212 cubic feet, making it perfect for apartments or compact home installations. With an incredibly small safety clearance of just 6 cm (2.4 in), it can be installed closer to walls than most electric heaters, saving precious space. Thanks to its innovative internal air tunnel, the heater warms up to 25% faster while extending the lifespan of its industrial-grade heating elements.
Eco-Friendly Construction
Not only does the CLIFF Mini offer high performance, but it’s also designed with sustainability in mind. The heater’s ribs are made from the stainless steel cutouts of HUUM’s larger STEEL heaters, reducing waste by producing two heaters from a single metal sheet. This clever reuse of materials showcases HUUM’s commitment to environmental responsibility without compromising quality or durability.
Superior Steam, Sleek Design
Despite its compact footprint, the CLIFF Mini boasts a large rock capacity of up to 132.3 lbs (60 kg), resulting in long-lasting, mild, and luxurious steam. Its vertical, stone-forward structure maximizes the surface area for stone contact, enhancing the quality and consistency of heat and löyly (steam). With exposed stones and a polished stainless steel body, the heater becomes a statement piece that complements any modern sauna interior.
