For Saunas From 530 to 1060 ft³ / 15 to 30 m³
The organic and minimalist design of the Hive 15 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 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 a milder steam. In our selection, we have rounded olivine diabase stones, 5-10 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
- Adjustable Legs
- Pre-Installed HIVE Air Tunnel
Recommended Selections:
- Control Unit
- Stones (2-4 in / 5-10 cm)
