Fill a mid-to-large sauna with deep, enveloping heat — and control it from anywhere — with the Huum Hive Electric Sauna Heater (15kW) + WiFi Control Unit, a floor-standing heater built to strike the perfect balance between power and efficiency.
Rooted in thousand-year-old Nordic sauna traditions, Huum combines that heritage craftsmanship with modern engineering. The Hive features 13mm heating elements — the largest diameter on the market — for outstanding durability, heating up fast, holding heat longer, and producing rich, generous steam session after session. Its floor-standing design commands attention in the room while the included UKU 15kW WiFi Controller puts full control in your pocket: preheat before you arrive, fine-tune the temperature on the fly, or schedule sessions in advance, all through the Huum app.
Purpose-built for mid-to-large saunas of 15–30 m³, making it well suited to family sauna rooms, garden sauna cabins, and home wellness spaces that want smartphone control instead of a fixed local panel.

The included UKU 15kW WiFi Controller connects to the Huum app, letting you preheat, adjust temperature, and schedule sessions from your smartphone, wherever you are.
