If you want a modern heater that prioritizes airflow and stone mass, the STEEL 10.5 kW design is built around those fundamentals. The built-in air tunnel supports effective airflow and faster heat-up behavior, while the 150 kg / 330 lb stone capacity helps produce a more even, comfortable steam character across properly sized rooms.
This package is also built to simplify your build plan. With the UKU Local controller and the correct style of rounded stones included, you can focus on room construction and ventilation details instead of piecing together core components across multiple orders. UKU Local keeps operation straightforward from an in-sauna wall control panel, while still allowing future expansion if you decide you want app-based control later.
HUUM’s approach emphasizes stainless-steel construction, modern controls, and practical performance for repeatable sauna sessions. Warranty terms for electrical heaters and control units support long-term ownership when installed and operated according to requirements.
