HUUM produces five electric sauna heater families, CORE, DROP, CLIFF, HIVE, and STEEL, each engineered in Estonia with a shared focus on maximizing stone mass relative to heater size.
HUUM’s compact, floor-mounted electric sauna heater features a distinctive matte black finish and optional bench integration. The Core is available from 6 kW to 11 kW and suits sauna rooms from roughly 5 m³ to 16 m³. It is a strong fit for modern sauna interiors where the heater is meant to blend into the room rather than stand apart from it.
The flagship model and the most widely specified. Its wall-mounted, teardrop-shaped stainless steel cage holds up to 122 lbs of exposed basalt stones. HUUM Drop is available from 4.5 kW to 9 kW and suits sauna rooms from roughly 3 m³ to 13 m³. It’s the natural choice when löyly quality is the primary consideration in a compact, wall-mounted format.
The HUUM Cliff is designed for rooms with limited floor space or wall clearance. Its slim, vertical profile allows remarkably short safety distances from combustible surfaces. CLIFF is available from 6 kW up to11 kW in its floor-standing format, covering rooms up to approximately 17 m³, with a separate 3.5 kW CLIFF Mini wall-mounted option for very small sauna rooms.
The HUUM HIVE brings a distinctive beehive-inspired, round design to larger sauna rooms and holds up to 529 lbs of stones, the highest capacity in the HUUM electric range. Available in 12 kW, 15 kW, and 18 kW outputs, it suits rooms from roughly 12 m³ to 28 m³ and is a popular choice for dedicated sauna rooms and commercial installations where steam quality and long-session performance are the priority. For smaller rooms that still want the beehive stone-basket aesthetic, the HIVE Mini covers 6 kW, 9 kW, and 10.6 kW outputs for rooms in the roughly 5 m³ to 16 m³ range.
The HUUM STEEL Heater carries an industrial aesthetic and is built for larger or commercial sauna environments, available across a similar output range to CLIFF (6 kW, 9 kW, 10.5 kW), with a STEEL Mini 3.5 kW option for smaller spaces. Higher wattage configurations make it a strong fit where a compact heater’s residential scale is insufficient.
Note: Models at the lower end of each family’s range can typically run on a single-phase supply (depending on circuit configuration and local wiring standards), while higher-output models may require a three-phase supply depending on your region and installation. Confirm your available supply and the specific threshold for your area with a qualified electrician before selecting a model. All five families work with the UKU Wi-Fi controller for app-based scheduling and remote preheat.
To choose the right kilowatt rating for your HUUM heater, start by calculating your sauna room’s volume in cubic metres (length x width x height). The standard baseline is 1 kW per 1 m³ of room volume.
For UK installations, most domestic single-phase supplies will support a meaningful portion of the HUUM range on a dedicated circuit; heaters above that threshold typically require a three-phase supply. Consult a qualified electrician before purchasing if you’re considering a higher-output model, since the exact cutoff depends on your existing wiring and local supply capacity.
HUUM’s own sizing tool is available on the HUUM website and gives precise recommendations based on your room dimensions and construction type.
A qualified electrician must install every HUUM electric sauna heater on a dedicated circuit with RCD protection. This is both a safety requirement and a condition of the product warranty.
For full technical detail, refer to the HUUM installation manual supplied with your heater.
