Built for larger saunas where space efficiency is still a priority, the HUUM CLIFF 11 combines high heating power with a sleek, space-saving design. This slender 11.0kW electric sauna heater features remarkably small safety distances, making it an excellent choice for sauna layouts with limited clearance.

The CLIFF 11 is engineered for sauna rooms ranging from 354 to 566 cubic feet, delivering reliable, even heat for spacious sauna environments. Thanks to its well-optimized internal structure, safety distances from the walls are reduced to as little as 6 cm on smaller models and 12 cm on larger models, allowing for greater flexibility in installation without sacrificing safety or performance.

Despite its powerful output, the CLIFF 11 maintains a clean, vertical profile that maximizes usable interior space while complementing modern sauna aesthetics. As part of the CLIFF series, it reflects HUUM’s thoughtful approach to engineering—balancing efficiency, performance, and design in a compact form factor.

For those building a larger sauna but working within spatial constraints, the HUUM CLIFF 11 offers a refined, high-capacity heating solution designed to fit beautifully and perform consistently.
