HUUM Steel 9 package: a 9 kW floor column, UKU control, and stones for saunas from 318 to 529 cubic feet
The HUUM Steel 9 package pairs the floor standing Steel 9 electric sauna heater with its control and stones for rooms from 318 to 529 cubic feet. The 9 kW heater is a stainless steel column made in Estonia. It measures just 12.6 inches square and 38 inches tall, weighs 33 pounds, and needs only a few inches of clearance from the wall. An internal air duct brings the room up to temperature up to 25 percent faster. The column holds 331 pounds of stones in direct contact with the heating elements for soft, steady heat.
The package includes the heater, a HUUM UKU control with its sensors and cables, and 330 pounds of rounded olivine sauna stones. The UKU lets you set the temperature from 104 to 230 degrees and schedule the sauna to start up to 48 hours ahead. On the page you choose the control: the standard UKU, or the Wi-Fi, Mirror, or Gold version that lets you start the sauna from your phone. A safety rail, a reflector panel, an embedding flange, and a bucket and ladle set are optional. Want the most power in this column style? See the HUUM Steel 10.5 heater package. The HUUM Steel 9 package ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What is in the STEEL 9 package?
The 9kW slim floor-standing heater, a complete UKU control system with temperature and door sensors, and 330 pounds of 1 to 2 inch rounded olivine stones, per the includes tab. One order covers heater, control, and stones for a mid-size sauna.
What size sauna is it combined for?
Rooms from 318 to 529 cubic feet, per the specification table – the middle slot in the STEEL package line. Match your measured room volume to the range before ordering; the 6kW and 10.5kW versions bracket it.
Can I run the sauna from my phone?
Select a Wi-Fi UKU control in the Sauna Heater Controls options and the HUUM mobile app starts and adjusts the sauna from anywhere. The description lists Wi-Fi as optional, so the base UKU Local digital control is the non-connected alternative.
What safety features are built into the control?
Per the features tab: overheat protection, a child safety lock, a door sensor that keeps heat inside the room, and a remotely mounted main control module. The panel displays set and actual temperature across its 104 to 230 degree Fahrenheit range.
Do I need to buy stones separately?
No – the package includes 330 pounds of rounded olivine stones sized 1 to 2 inches, per the includes tab, filling the heater’s unusually large capacity for its slim 12.6-inch footprint. Stack them per the manual with the stones contacting the elements.
What warranty applies?
A limited 5-year warranty, excluding heating elements on the heater side. The STEEL heater is stainless steel inside and out and made in Estonia; file the order paperwork with your sauna documents in case service is ever required.
