HUUM Sauna Heaters

HUUM is widely considered a top-tier premium heater due to its high stone capacity and superior steam quality. To ensure peak performance, we emphasize that the bather must perform an annual stone audit; restacking the stones once a year prevents settling and dust buildup, which maintains the airflow necessary to prevent the stainless steel elements from overheating.

Yes. The HIVE series is available in both electric and wood-burning configurations. We provide the HIVE Wood and HIVE Flow models for off-grid or traditional installations, offering the same sculptural design with high-efficiency fireboxes engineered to retain 75% of the thermal energy within the stone mass.

Absolutely. We encourage users to pour water over the hot stones to create leil, the soothing steam that enhances the session. Unlike many standard electric heaters with small rock trays, HUUM units are engineered to handle significant water quantities, transforming it into a gentle mist rather than a harsh, dry sizzle.

Yes. By pairing your heater with the UKU WiFi control system, you can manage settings via the HUUM app. This is a highly sought-after feature for our US clients, enabling them to preheat their sauna remotely while returning from skiing or a commute, ensuring the cabin is at 176 degrees Fahrenheit the moment they arrive.

We recommend the DROP for users seeking a compact, wall-mounted heater that saves floor space in small to medium home saunas. The HIVE Mini is a floor-standing unit designed for medium rooms where a larger stone capacity is desired to produce a more lingering, soft steam quality.

The uniqueness lies in the minimalist rounded shape and the high rock-to-metal ratio. By exposing more stones and utilizing less metal, we find the heaters increase the production of negative ions in the air, resulting in a cleaner and more refreshing respiratory environment compared to traditional cabinet heaters.

With correct sizing, a HUUM heater increases temperatures by roughly 10 degrees Celsius every 8 minutes. We estimate a total heat-up time of approximately 45 to 60 minutes to reach a therapeutic 176 degrees Fahrenheit, though large glass windows or stone walls will extend this duration.

The original HIVE is a high-output unit designed for large residential or commercial spaces up to 1,060 cubic feet. The HIVE Mini is a slender version optimized for home saunas up to 530 cubic feet, allowing for a premium floor-standing aesthetic in a more compact footprint.

The investment in WiFi technology is an investment in usability. We have observed that owners who utilize the UKU WiFi system use their saunas twice as often as those with manual controls, as the ability to preheat the room remotely removes the primary hurdle of the hour-long warm-up window.

Our technical standard for HUUM sizing is 1 kW of heater power for every 35 cubic feet of room volume. We also add penalty volume for heat-loss surfaces, such as adding 6 cubic feet for every 1 square foot of uninsulated glass or stone walls to ensure the heater reaches its target temperature.

We suggest starting with dry kindling and gradually adding seasoned logs. Use the ash drawer to manage oxygen flow—open it roughly 10mm to start the fire, and then close it to a gap of 2-3mm once burning to maintain a clean, efficient flame without overheating the metal shell.

The HIVE Wood 13 is suitable for rooms between 212 and 459 cubic feet, while the HIVE Wood 17 is ideal for larger spaces up to 565 cubic feet. Both models require strict adherence to safety clearances, typically requiring 190mm to 500mm of distance from combustible side walls.

HUUM electric heaters reach up to 230 degrees Fahrenheit, making them the hottest heaters available in North America. This is achievable because HUUM utilizes SGS safety certifications, which are fully recognized by US inspectors, whereas UL-listed heaters are restricted to a maximum of 194 degrees Fahrenheit.

We recommend selecting based on your adjusted cubic volume, mounting preferences, and electrical availability. For home saunas, wall-mounted DROP models are popular for space-saving, while the floor-standing HIVE models are preferred for their commercial-grade stone mass and visual impact.

HUUM provides a limited 5-year residential warranty on the heater shell and components. We note that this coverage does not extend to the heating elements or stones, as these are consumable items that require periodic replacement depending on the frequency of use and water quality.

Usage is managed through the wall-mounted digital controller or the UKU app. Simply wake the screen, rotate the dial to your desired temperature, and press to engage the heating cycle. The system will automatically manage the thermal stratification until your target heat is achieved.

To establish the cloud connection, hold the UKU control button for 10 seconds to enter the settings menu. We recommend navigating to the Wi-Fi SSID menu and selecting your local 2.4 GHz network to link the controller to your smartphone app for remote operation.

This button is the high-limit safety reset. In very small saunas, the sensor may trip if airflow is restricted or if the stones are packed too tightly. If the heater stops firing, we suggest checking for a tripped high-limit switch and resetting it once the unit has fully cooled down.
