Huum STEEL Series Sauna Heater

STEEL is a slim electric sauna heater with remarkably small safety distances, which makes it perfect for saunas with limited spaces. Thanks to its well-optimized structure the safety distances from the walls are brought down to just 5 cm with smaller models and to 10 cm with larger models. STEEL heater also comes in an even slimmer 3,5 kW wall-mounted model which is particularly suitable for very small sauna rooms.

Respect for space

TEEL heater was developed with small home saunas and space saving in mind. Therefore it has a very slim design and significantly reduced safety distances from the walls. The small safety distances are achieved by optimizing the structure and placement of the internal air tunnel. However, the compactness does not come at the expense of efficiency. The internal air tunnel placed in the center of the heater provides effective airflow, speeds up the heating process by 25% and prolongs the lifespan of the heating elements.
