HUUM HIVE Mini 9kW Electric Sauna Heater

Overview

The HUUM HIVE Mini 9 kW electric sauna heater is a floor-standing stone heater for sauna rooms measuring approximately 283–460 cu. ft. Its rounded stainless-steel form makes the stones a visible part of the sauna interior, while its compact footprint suits spaces that need substantial heat output without the size of the full HIVE series. HUUM’s US specifications list a 240 V, 2-phase connection for this model.

Features

• 9 kW electric output: Designed for sauna rooms within HUUM’s published 283–460 cu. ft. range.
• HIVE Mini profile: A cylindrical, floor-standing heater that presents the stones as a design feature.
• 330 lb (150 kg) stone capacity: A large stone mass supports prolonged heat storage and traditional water-on-stone bathing; stones are sold separately.
• Stainless-steel details: HUUM identifies durable stainless-steel construction.
• Air tunnel included: HUUM states that the air tunnel is standard with HIVE Mini models from 2025 onward.
• Adjustable support legs: Included to help level the heater on a suitable floor.
• HUUM UKU compatible: A compatible control system is required and sold separately.
• 240 V, 2-phase supply: The US manufacturer specification lists a 50 A breaker and minimum 8 AWG power cable for the 9 kW configuration.
• Room-centered placement option: The freestanding design can be positioned where the room layout and required clearances allow.
• Manufacturer clearances: Clearance dimensions vary by model and must be followed as shown in the current installation manual.

Specifications

What's Included

HUUM lists the HIVE delivery set as the electric heater, four adjustable legs, the air tunnel and the heater installation/operation manual. Air tunnel inclusion is standard for HIVE Mini models beginning in 2025.

Required separately: A compatible HUUM UKU control system and approximately 330 lb of suitable sauna stones. Confirm current box contents for the exact unit before installation.

Installation

• Confirm the room volume falls within HUUM’s 283–460 cu. ft. range and account for uninsulated masonry, tile or glass surfaces according to the manufacturer’s volume guidance.
• Have a licensed electrician verify the required 240 V, 2-phase service, 50 A circuit protection, minimum 8 AWG conductors, grounding and local-code requirements. The BathingBrands sheet says “240V/1PH,” which conflicts with HUUM’s US specification of 240 V, 2~; the electrician and current manufacturer manual should govern the installation.
• Place and level the heater on a stable, noncombustible supporting floor, using its adjustable legs as directed.
• Install the compatible UKU control and sensor at the locations stated in the control and heater manuals.
• Maintain the listed safety distances to walls, benches and ceiling. Do not box in or obstruct the heater or air tunnel.
• Arrange stones as instructed to protect the heating elements while preserving airflow. Do not operate without stones or with the heater covered.

Operation and Usage

Use the HIVE Mini only with a compatible control system installed and configured according to its manual. Allow the sauna to preheat, then use clean water sparingly on the stones for traditional steam. Never pour water onto the control, wiring or exposed electrical parts.

• Keep towels, clothing, oils and other combustible items away from the heater.
• Supervise children and keep people clear of hot surfaces; use a safety rail where appropriate for the room layout.
• Switch off and have the unit checked if wiring, controls, stones or heater parts are damaged or the heater operates abnormally.
• Sauna bathing involves heat exposure and dehydration risk. Avoid alcohol, drink fluids as appropriate and leave the sauna if you feel unwell. Ask a healthcare professional about sauna use if a health condition or medication may affect heat tolerance.
