Description

Engineered for maximum performance in minimal space, the HUUM STEEL 10.5kW Sauna Heater delivers powerful heating capacity in a sleek, ultra-slim profile. Designed for sauna rooms between 354 and 566 cubic feet, this floor-standing electric heater is ideal for modern spaces, compact rooms, and installations requiring reduced safety distances.

The STEEL Series features HUUM’s advanced internal air duct system, allowing the heater to warm up to 25% fasterwhile maintaining exceptional heat distribution and efficiency. With a large 331-pound stone capacity, the heater produces long-lasting, soft, and balanced steam that mimics the feel of a traditional wood-burning sauna — but with the convenience of electric power.

The STEEL 10.5 works with HUUM UKU Controls, giving users precise command over temperature, scheduling, safety, and heating modes. Built from premium stainless steel and crafted in Estonia, this heater combines modern engineering with timeless sauna tradition.
