Description

Elegant & Long-Lasting Steam, Perfect for Smaller Saunas

The compact Steel Mini electric heater with extremely short safety distances is a wall-mounted model that is especially suitable for small steam rooms. Thanks to the well-optimized design the safety distances of Steel Mini from the walls are only 5 cm / 2.5″. Steel Mini is a narrower version of the Steel heater.

The WiFi-compatible HUUM Steel Mini 3.5 kW free-standing sauna heater is designed for home sauna rooms from 124 to 212 cubic feet. The HUUM Steel Mini 2.5 kW sauna heater’s large stone capacity creates a consistent, soft heat for a superior sauna experience that can be wet or dry in use. The sauna unit is crafted of durable stainless steel, features industrial-grade stainless steel heating elements, and can hold up to 132 pounds of sauna stones. The unit is engineered so that the sauna stones are in direct contact with the heating elements for more efficient heat transference.

HUUM sauna heaters are precision-crafted in Estonia to provide years of dependable, efficient operation. All HUUM heaters come with a limited 5-year warranty and is fully serviceable. Choose from their standard UKU Digital Wall Control, or upgrade to the popular UKU WiFi Control options.

The organic and minimalist design of the Steel Mini 3.5 kW heater takes up very little space and makes a statement piece of your sauna. For controls, choose from HUUM UKU units (Local, Wi-Fi, or Glass). With a touch of a dial and a range of sensors, you can easily control many aspects of your sauna experience, including temperature, steam, and lighting. Local comes in different colored plastic cases as well as a wood option made of thermo-treated ash. When you opt for UKU WiFi, you add in control of your sauna by a smartphone app, allowing you to put the sauna to work while being far from home. UKU Glass is elegant glass with integrated WiFi.

Sauna Stones

Stones aren’t included, so we highly recommend adding them – unless you already have your own dedicated sauna stones. These stones available for selection are rounded and will complement your HUUM heater’s design, as well as give milder steam. In our selection, we have rounded olivine diabase stones, 3-5 cm. The stones are durable and have high heat capacity. You can also use other types of stones in HUUM heaters, except decorative stones because they can break easily.

This Set Includes:

  • Electric Stove
  • Wall Mount

Recommended Selections:

  • Control Unit
  • Stones (1-2 in / 3-5 cm)
