It's a great heater but it is very large, so it dominated the small corner we put it in.

Description

Elegant & Long-Lasting Steam in Free Standing Form

Hive electric sauna stove is an elegant solution for bigger saunas, for example, for spas and gyms. This floor-mounted stove holds up to 550 lb / 250 kg of stones, which ensures a long-lasting hot steam even for larger groups, without compromising on design.

The HUUM HIVE 18 is a premium quality floor-mounted 18-kilowatt electric sauna heater designed for large sauna rooms from 636 to 1236 cubic feet. The WiFi compatible HIVE 18 sauna heater is engineered for reliable daily use in commercial wellness centers such as health clubs, day spas, and gyms. Its massive 550-pound stone capacity ensures a soft, consistent, high heat and allows for better steam for larger groups. The HIVE 18 is constructed of high-grade stainless-steel and equipped with professional-quality stainless-steel heating elements. The sauna unit is designed so that its sauna stones are in direct contact with the heating elements for more efficient heat transference and can be used wet or dry.

HUUM Hive Series heaters are precision-crafted in Estonia to provide years of dependable operation. HUUM HIVE Heaters are SGS Listed to ensure quality and safety. The Hive 18 kW sauna heating unit carries HUUM’s 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.

Key Features

  • Stainless steel construction
  • High stone capacity (550 lb / 250 kg)
  • 5-year guarantee
  • Free standing heater with external control
  • Size: 29.53" h × 22.05" diam.

For Saunas From 636 to 1236 ft³ / 18 to 35 m³

The organic and minimalist design of the Hive 18 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)
