HUUM Steel 10.5kW: Space-Efficient Sauna Heater with Massive Stone Capacity

Premium Estonian design with exceptional heat performance for medium to large sauna spaces

The HUUM Steel 10.5kW is an innovative electric sauna heater engineered to deliver powerful heating performance while maintaining remarkably small safety clearances. With only 4" (10cm) wall clearance requirements, this sleek, elegant heater maximizes usable space in your sauna while delivering the exceptional performance expected from premium Estonian craftsmanship.

Designed for sauna rooms from 353 to 600 cubic feet, the Steel 10.5kW features an impressive 331-pound stone capacity that creates a consistent, enveloping heat perfect for both traditional wet sauna sessions and dry heat experiences. Its ingenious internal air duct system accelerates heating time by 25%, ensuring your sauna reaches optimal temperature efficiently without compromising on the soft, pleasant heat distribution that characterizes an authentic sauna experience.

Precision-crafted in Estonia using premium stainless steel, each HUUM heater undergoes rigorous quality testing and comes with a comprehensive 5-year limited warranty. With fully serviceable components and industrial-grade heating elements, the Steel 10.5kW represents a superior long-term investment for discerning sauna enthusiasts seeking substantial heating power in an elegant, space-saving design.

Sophisticated Control Options

Customize your sauna experience with HUUM's advanced UKU control systems:

  • UKU Local — Wall-mounted control panel available in thermo-treated ash wood or colored plastic finishes, featuring intuitive dial controls for precise temperature, steam, and lighting management
  • UKU WiFi — Combines all Local functionality with smart connectivity through a dedicated mobile app, allowing remote sauna preparation from anywhere
  • UKU Glass — The ultimate luxury interface with sophisticated glass design and integrated WiFi connectivity, perfectly balancing aesthetics with cutting-edge technology

Sauna Stone Recommendation

While stones are purchased separately, we recommend premium 3-5 cm (1-2 inch) rounded olivine diabase stones to maximize your HUUM heater's performance. These specially selected stones offer:

  • Exceptional durability with superior heat capacity for longer-lasting heat maintenance
  • Naturally rounded edges that produce gentler, more consistent steam dispersion
  • Optimal sizing for balanced heat distribution throughout your sauna space

While alternative stone types can be used with your HUUM heater, we advise against using decorative stones that may crack under intense heat, potentially affecting your heater's performance and longevity.
