Compact Stainless Steel Design Industrial-Grade Heating Elements 💨 Internal Air Duct — 25% Faster Heat-Up Direct Stone-to-Element Contact 🎛️ UKU Control — Included 🪨 Sauna Stones — Included 📱 Wi-Fi Optional — HUUM App Settable Time · Temperature · Delay 🇪🇪 Made In Estonia

The HUUM Steel Series is a complete, ready-to-install sauna heater package — the Steel heater, UKU control panel, and premium sauna stones all included in a single purchase. Designed for saunas where space is at a premium, the Steel's compact footprint delivers full HUUM performance without requiring the larger floor presence of the HIVE range. The internal air duct is the Steel's defining engineering feature: by channelling airflow through the heater internals, it achieves heat-up times up to 25% faster than conventional electric heaters of comparable output.

Direct stone-to-element contact produces the long, mild, consistent heat that defines a genuinely restorative sauna session — exposed stones provide enveloping warmth that outlasts the session cycle rather than fading mid-session. The UKU control panel manages temperature, session time, and delay start with precision. Optional Wi-Fi integration via the HUUM mobile app enables remote pre-heating from anywhere. Built from durable stainless steel with industrial-grade heating elements in Estonia.

Compact footprint. 25% faster heat-up. UKU control, stones, and heater — all in one package. The HUUM Steel — complete from day one. 🌿

Internal Air Duct — 25% Faster Heat-Up Than Conventional Heaters

The HUUM Steel's advanced internal air duct is its most quantifiable engineering advantage. By channelling airflow through the heater's internals rather than relying on natural convection alone, the Steel reaches session temperature up to 25% faster than a conventional electric heater of equivalent output. This means less waiting, less energy consumed during heat-up, and more time in the sauna. The air duct also improves heat distribution through the stone mass, contributing to the consistent, enveloping warmth the Steel delivers throughout every session.

💨Internal air duct — 25% faster heat-up — the HUUM Steel's internal air duct is its headline engineering specification. The duct channels airflow through the heater's internals during warm-up, improving convective heat transfer through the stone mass and reducing the time from switch-on to session-ready temperature by up to 25% compared to conventional heaters of equivalent output. Faster heat-up means less waiting, lower energy consumption during the warm-up phase, and a more practically useful heater for daily sessions where time to temperature matters

🪨Direct stone-to-element contact — long, mild, consistent heat — the Steel's stones sit in direct contact with the heating elements rather than above a separate heat chamber. Direct thermal contact heats the stone mass more efficiently, produces longer-lasting heat retention between pours, and generates a more consistent, mild warmth throughout the session. The exposed stone arrangement also makes ladling water straightforward — immediate, responsive steam from the first pour

📦Compact design — ideal for space-limited saunas — the Steel's compact dimensions make it the natural choice for saunas where floor area is limited or where a larger heater would dominate the available space. The compact footprint delivers full HUUM performance — internal air duct, direct stone contact, UKU control — without the larger presence of the HIVE range. Perfect for compact home saunas, retrofit installations, and any space where size constraints rule out a larger unit

🎛️UKU control panel — time · temperature · delay · included — the UKU panel ships with the Steel package. Set the target temperature, session duration, and delay start time directly from the panel — control your session precisely from inside the sauna without needing a phone or separate interface. The UKU's multi-setting capability covers every daily use scenario from a quick solo session to a pre-scheduled long evening session

📱Optional Wi-Fi — HUUM mobile app remote control — the Steel supports optional Wi-Fi integration via the HUUM mobile app, enabling remote pre-heating from anywhere. Start the sauna from the office, the gym, or the couch before you step outside — the Steel reaches your preferred temperature by the time you arrive at the sauna door. Contact us to discuss adding Wi-Fi capability to your Steel package

🏗️Durable stainless steel — industrial-grade elements — made in Estonia — the Steel's stainless steel construction and industrial-grade heating elements are built for regular daily use over the long term. Estonian precision craftsmanship applied to a compact form — the same manufacturing standards as the HIVE range in a smaller, more versatile footprint
