HUUM Hive Mini 9 kW 240V Electric Sauna Heater- Complete Package Options

Shapes Inspired by Nature

The HIVE sauna heater draws inspiration from nature, with its round design mimicking the hive of wild bees. Elegant stainless-steel arcs encircle the sauna stones, enhancing their natural beauty.

Representing the generous warmth of the Nordic sauna, the HIVE heater brings people together. It acts as the heart and focal point of the sauna, offering the perfect atmosphere for sharing stories and enjoying a genuine sauna experience!

Authentic Soft Steam, Inspired by Tradition

HUUM sauna heaters use minimal metal, ensuring that most of the heat comes from the stones rather than the metal itself. This design maximizes the release of beneficial negative ions in the air, similar to those found in traditional wood-heated saunas.

The combination of this and the unusually large number of sauna stones is the key to the soothing, therapeutic, and long-lasting steam produced by our sauna heaters.

HUUM Hive Air Tunnel
The HUUM Hive Air Tunnel, included and pre-installed on your HIVE sauna heater, speeds up heating by 25% while extending the lifespan of heating elements. Made from premium stainless steel, it reduces the need for sauna stones by approximately two boxes, saving you time and money. Perfectly positioned in the center of the heater, it ensures efficient and even heat distribution for an exceptional sauna experience.

Plan your HUUM HIVE or HIVE Mini installation with helpful manufacturer resources, including heater manuals, UKU control documentation, main module instructions, wiring diagrams, specification sheets, and installation videos.

Before installation, we recommend sharing these resources with your licensed electrician and sauna installer so they can review heater placement, electrical requirements, control setup, stone loading, safety clearances, and installation requirements in advance.

Always follow the official HUUM installation manuals, local electrical code, and guidance from your licensed electrician. NW Immersion is also here to help with heater sizing, package selection, and general installation planning before your order ships.
