The original Pilari-IKI heater model is an all time biggest-selling electric heater by IKIKiuas.IKI 6 kW is suitable for 5-9 cubic metre sized saunas. The heater can be fitted into a very small space thanks to its small size (24 cm in diameter) and the small safety distances to inflammable materials (10 cm). The stone capacity is still a massive 120 kilos, which is heated up efficiently by U-shaped resistors through the entire height of the heater. Small saunas get fully heated in 45-60 minutes. The large amount of stones guarantees a hefty oxygen-rich sauna experience, plenty of heat for those who like it hot and moist enough for everyone else to enjoy and relax in.
