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 heater is best suited for medium sized sauna rooms, 7–12 cubic metres in size. The stainless steel mesh frame holds an impressive 140 kilos of stones, which give out ample heat to the most devoted of sauna-worshippers. The heater is available with a mounted control unit or separate control panel.
