IKI 7.5 kW is the first ever IKI electric heater. It has been warming Finnish saunas and hearts for nearly ten years. The intensity of the steam in the sauna can be controlled by throwing water either on top or on the sides of the heater. From the top you get a more hefty heat and from the sides milder and more humid steam. The 140 kilos of stones warm up in about an hour. The heater is constructed from separate parts and, unlike other IKI heaters, this has a separate resistor unit. The heater stands on top of a stylish stainless steel table.
