Description
The HUUM HIVE Mini is a floor-standing electric sauna heater that brings the HIVE’s open steel lattice and very large stone mass to smaller sauna rooms. It holds up to 150 kg of stones, a capacity that gives long-lasting, even steam well beyond what its compact 460 mm diameter suggests. It is available in 6 kW, 9 kW and 10.5 kW outputs, covering sauna rooms of 5–16 m³, and connects to either a single-phase 230 V or three-phase 400 V supply; the HIVE air tunnel has been included as standard since April 2024. A HUUM UKU control console (Local or Wi-Fi) and around 150 kg of 5–10 cm stones are required and sold separately; for larger rooms there is the full-size HIVE.

Installation
Installation and maintenance must be carried out by a certified electrician, with the electricity supply isolated at the fuse panel before any work begins. Under IEC 60364-7-703 and BS 7671:2018 an electric sauna heater does not have to be connected through an RCD, and for reliable operation the manufacturer recommends that the heater supply is not run through one; other electrical devices in the sauna room should be RCD protected. A local point of isolation covering all live conductors is recommended. The installation manual in the Downloads tab and local wiring regulations must be followed. The connection cable must be heat-resistant rubber-insulated cable (SIHF-JB or equivalent); PVC-insulated cable must not be used, and any junction box in the sauna room must be waterproof and mounted no higher than 500 mm from the floor. When sizing the heater, add 1 m³ of calculated room volume for every square metre of uninsulated brick, tile, glass or log wall in the sauna room. A diagram of the safety distances is provided in the image gallery.
Sauna stones
The HIVE Mini requires approximately 150 kg of 5–10 cm stones (around 10 boxes), sold separately; natural stones such as olivine diabase or olivine are recommended. Wash the stones before use and lay them one by one, keeping the air tunnel free of stones and making sure neither the air tunnel nor the tops of the heating elements remain visible, otherwise the stated safety distances no longer apply.
