HUUM HIVE Electric Sauna Heater 12/15/18kW

HUUM HIVE Electric Sauna Heater 12/15/18kW

The HUUM HIVE brings modern elegance to larger saunas such as those in health clubs, spas and gyms. This floor-standing electric heater holds 528 lbs. of stones for a soft, long-lasting heat, and its air tunnel shortens heat-up time and extends the life of the heating elements. It is offered in three sizes: HIVE 12 (12 kW, order no. H1003012), HIVE 15 (15 kW, order no. H1003022) and HIVE 18 (18 kW, order no. H1003032).

The heater does not run on its own: it requires a HUUM UKU control, the UKU Extension Box and sauna stones, all sold separately. See What to Order With It below.

Installation Requirements

Minimum safety clearances (letters refer to the diagram below):

• Legs: Screw in the four included legs and adjust them so the heater is level and all four carry weight.
• Bench installation: The heater can be partly recessed into the sauna bench or floor. At least 13.8 in (350 mm) of the heater must stand above the bench surface. Use the embedding flange to cover the edges of the opening.
• Power connection: The power cable enters through the bottom cover of the heater. Crimping the power cable ends is mandatory.
• Stones: Use 2-4 in (5-10 cm) round stones. Lay them one by one, larger stones at the bottom and sides, and cover the heating elements so they are not visible. A stone container filled too sparsely is a fire hazard, and the clearances above do not apply if the elements are exposed.
• Sauna room height: Minimum 77 in (1950 mm).
• Two supply circuits: The HIVE 12, 15 and 18 are wired on two circuits through the UKU Extension Box; the breaker and wire sizes above are per circuit.
• Surface temperature: Installing the heater closer to flammable construction than the clearances above may cause a fire hazard.
• Wiring: Use heat-resistant power cable that meets UL 62; cable with PVC insulation is not allowed. A circuit breaker that disconnects all poles must be installed on the power circuit ahead of the sauna control. HUUM recommends connecting the heater without a GFCI breaker. Breaker and wire sizes above are from the installation manual; your electrician sizes the circuit to local code.
• Junction box: Must be waterproof and located no more than 19.7 in (50 cm) from the floor.
• Uninsulated walls: For any uninsulated brick, tile or glass wall, add 3.3 cu. ft. to the room volume for each 1 sq. ft. of that wall before choosing a size.
• One heater per room: Do not install more than one heater in the sauna room.
• Installation: Electrical work must be carried out by a licensed electrician, following the installation manual and local codes.

3-Year Limited Residential Warranty, 1-Year Limited Commercial Warranty: HUUM covers the HIVE with a 3-year limited warranty in residential use and a 1-year limited warranty in commercial use.
