HUUM Steel

The internal air duct structure is engineered to promote rapid air circulation, which allows the heater to warm your sauna room up to 25% faster than standard models.

No, the HUUM STEEL requires an external control unit to operate. You will need to purchase a compatible HUUM controller separately to manage your temperature and timing settings.

One of the key advantages of the STEEL model is its slim profile and small safety distances. While you should always consult the installation manual for specific local codes, its design is optimized for tighter spaces where wall clearance is limited.

The substantial stone capacity—331 lbs—is designed to provide a consistent, mild, and long-lasting heat. This large mass of stones retains heat effectively, making it ideal for extended sauna sessions where you prefer a softer, more enveloping steam.

The HUUM STEEL is rated for sauna rooms between 354 and 566 cubic feet. If your sauna falls within this volume range, it is a powerful, professional-grade choice; however, you should verify your room's exact dimensions before purchasing.

The high-quality stainless steel is built for durability and performance in high-heat, high-moisture environments. To keep it looking its best, simply wipe down the exterior periodically with a damp cloth and ensure the stones are restacked or replaced occasionally to maintain optimal airflow.
