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.
