Description
Heat larger saunas with the Huum Hive 18kW electric sauna heater, made for sauna rooms of 636 to 989 cubic feet. The floor-standing HIVE is built for larger and commercial saunas such as spas, gyms and health clubs. Its air tunnel shortens heat-up time and extends the life of the heating elements.
It is sold as the heater only, which makes it a simple swap if you already have a HUUM UKU control, extension box and stones. It runs from a HUUM UKU control (UKU Local, UKU 4.2 Wi-Fi or UKU Glass, sold separately), and like every heater of 12kW and up it also needs a UKU extension box. You can add the control, the extension box and the sixteen boxes of small sauna stones it needs (33 lbs each) on this page. Designed and engineered in Estonia.
