Red Dot Design Excellence at Full Power
The HUUM Cliff sauna heater continues the legacy of design innovation that earned the Cliff series its Red Dot product design award. This internationally recognized accolade celebrates products that combine aesthetic sophistication with practical functionality, and the 10.5kW model exemplifies both qualities at the highest level.
Meticulously crafted from premium stainless steel in Estonia, each unit reflects Nordic engineering expertise and manufacturing precision. The elegant vertical profile, inspired by the dramatic Nordic cliffs of the Baltic region, creates a striking focal point in your sauna while delivering the heating performance larger rooms demand. It's a design statement that elevates your entire sauna experience.
Compact Clearances, Powerful Performance
What makes the Cliff hot heater truly exceptional is how it packages 10.5kW of heating capacity within a remarkably compact footprint. The well-optimized structure maintains safety distances of just 12 cm (approximately 4.7 inches) from walls — an engineering achievement that seems almost impossible for a heater of this power level.
This space-saving design philosophy means you can install the HUUM Cliff 10.5 kW 240V in rooms where traditional heaters of comparable power simply wouldn't fit.
Whether you're retrofitting an existing sauna or designing a new installation, these minimal clearances give you layout flexibility that was previously unattainable with heaters in this power range.
Optimal Heating for Larger Home Saunas
The HUUM Cliff 10.5 is specifically engineered to heat sauna rooms between 354 and 566 cubic feet, making it ideal for more spacious residential installations.
With 10.5kW of power at your command, you enjoy rapid heat-up times and effortless temperature maintenance even in larger spaces. The substantial heating capacity ensures consistent warmth throughout your sauna, creating that perfect environment for authentic sauna bathing.
Advanced Smart Sauna Integration
As a modern 1PH electric sauna heater, the HUUM Cliff electric sauna heater operates on standard 240V residential power while offering seamless integration with cutting-edge sauna control technology.
The HUUM sauna heater works flawlessly with a sauna heater with Wi-Fi control systems, giving you unprecedented command over your sauna experience. Through the HUUM app, you can manage every aspect of your sauna sessions from anywhere. Start preheating before you leave work, fine-tune temperatures from the comfort of your bench, or create custom heating schedules that align perfectly with your lifestyle. This connectivity transforms traditional sauna bathing into a seamless modern wellness experience.
Superior Stone Capacity and Heat Quality
The Cliff 10.5's vertical architecture accommodates a generous volume of sauna stones, ensuring exceptional heat storage and steam generation.
When you pour water over the stones for that perfect steam, the heater's design promotes vigorous steam production and even distribution throughout your sauna room.
The premium stainless steel construction does double duty: it provides stunning visual appeal while efficiently conducting and radiating heat. This synergy between the metal housing and sauna stones creates the authentic heat quality that serious sauna enthusiasts demand.
Installation Flexibility and Professional Integration
The compact dimensions of the HUUM Cliff 10.5 translate into practical installation advantages. The 12 cm clearance requirement allows for flexible positioning within your sauna layout, maximizing usable space without compromising safety. The 240V sauna heater configuration integrates smoothly with residential electrical systems, though professional installation by a licensed electrician is essential for a unit of this power level.

The Cliff is made from stainless steel in Estonia, where sauna culture runs deep and manufacturing standards are exceptionally high. This heritage of precision engineering and quality craftsmanship ensures that every HUUM electric sauna heater meets rigorous performance and durability standards.
