Overview of HUUM Steel Electric Sauna Heater

HUUM Steel, a brother of the popular HUUM Cliff heater, has a large rock capacity, which guarantees mild and long lasting steam. HUUM is best known for just that special steam their sauna heaters produce, when you throw water on to the rocks. HUUM Steel has a built-in air tunnel, which ensures effective air flow and quick heating times for your sauna.

HUUM Cliff uses an external controller. Just like with every other HUUM, you can pick the most suitable HUUM UKU for your needs. UKU control systems are available with or without WiFi functionality. The WiFi enabled system allows you to control your sauna environment remotely from the app on your phone. 

Each HUUM sauna heater is compatible with any of our UKU control packages, ensuring universal suitability across all models.

HUUM Steel Configurations

HUUM Steel is available in 3.5kW, 6kW, 9kW, and 10.5kW. The smallest configuration, HUUM Steel Mini 3.5kW is a wall mounted sauna heater and notably smaller in physical size compared to the rest of this lineup. 

HUUM Steel 6kW, 9kW, and 10.5kW are physically exactly the same size, bigger heaters just have more heating elements inside the stainless steel cage.

Let’s go through the electric specs and appropriate room sizing for each HUUM Steel configuration:

HUUM Steel Accessories

We offer many optional accessories for HUUM Steel:

HUUM Rail S Safety rail - An accessory that increases safety in your steam room and helps to prevent accidental contact with the hot heater.

HUUM Reflect S - The reflector is an accessory for HUUM Steel sauna heaters that enables one to reduce the safety distances from the walls by 50%. The reflector is made of stainless steel, and it is mounted to the fins of the STEEL sauna heater. It is also possible to connect reflectors to obtain a larger surface.

HUUM Flange CS - When you want to embed your Steel into the sauna benches, you need an embedding flange. The embedding flange is made of stainless steel. It covers the rugged wooden cut rims around the heater, and gives a refined and smooth final result.

Conclusion

The Sauna Heater offers the largest collection of sauna heaters in the USA. We have multiple brand partners, out of which HUUM is our personal favorite when it comes to design & performance.

In case you need a bigger sauna heater, and the Steel lineup's biggest 10.5kW version is not enough for your needs, we recommend getting a Hive sauna heater from HUUM. HUUM Hive is available in 12kW, 15kW and even at 18kW configurations. HUUM also has wood-burning Hive heaters, which have gained a lot of popularity amongst authentic sauna lovers in the recent years.
