HUUM Steel Electric Sauna Heaters

What makes the Steel heater different from other HUUM models?

Think of the Steel as the clever engineer of the HUUM family. While the HIVE and DROP are sculptural centerpieces, the Steel is all about efficiency and a minimal footprint. Its slim design and remarkably small safety distances allow it to fit into tighter spaces without sacrificing the high stone capacity HUUM is famous for.

How does it heat up so fast?

It's all thanks to some clever internal engineering. The Steel heater features a unique internal air duct that speeds up air circulation, pulling cool air from the bottom and channeling it through the hot stones. This simple but brilliant design can get your sauna hot up to 25% faster than a standard heater of the same power.

What size Steel heater do I need?

The Steel series is incredibly versatile, with options for almost any room size. The compact STEEL Mini (3.5kW) is perfect for intimate saunas, while the powerful 9kW and 10.5kW models can easily handle larger family-sized rooms.

Is it compatible with UKU controllers?

Absolutely. The Steel heater is designed to work seamlessly with the full range of sleek HUUM UKU controllers, including the WiFi-enabled models that allow you to preheat your sauna from anywhere. You get the full, premium tech experience.
