How it heats
FERO is a small electric stone heater. Heat the rocks, ladle water for steam. Dual thermostatic controls, warm-white lighting, tempered glass door, Aerotherm ventilation on the Kohler home line. 4.5 kW is a modest heater — it is not a 9 kW Virta. Licensed electrician; Kohler notes this C1 kit includes the power cord to the dedicated supply.

Sizing
Match heater kW to insulated interior volume. Glass, stone, tile, or thin walls need more heater than a tight wood room of the same size. A licensed electrician completes the hookup from the nameplate — we do not guess breaker size. Email hello@selfcaresaunas.com to size the room first.
