Huum Steel sauna heater

Huum Steel sauna heater

Huum Steel has a design that is simple yet timeless. The curved details really soften the shape. Sometimes simple design is the hardest to do, and here Huum has succeeded to not overcomplicate it.

The benefits of the Steel heater:

* Durable stainless steel materials. This heater is the sibling of the Cliff heater.

* Quite a large quantity of rocks, 330 lbs (150 kg), which is perfect for endless steam.

* High quality, attested by warranty given by Huum, 5 years. Does not apply to heating elements.

Various heater control units can be used with this heater. Also, regular heater stones can be used instead of the rounded stones.
