HUUM CLIFF 6.0kW 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 6 cm with smaller models and to 12 cm with larger models. CLIFF heater also comes in an even slimmer 3.5 kW wall-mounted model which is particularly suitable for very small sauna rooms.
