The Harvia KIP80W is a premium 8.0kW wall-mounted electric sauna heater expertly designed for rooms ranging from 250 to 425 cubic feet. We provide this model as the primary solution for those seeking the precision of an external control system, as it requires the Harvia Xenio control for operation to deliver highly accurate temperature management and optional WiFi connectivity. This specific model is the right choice for high-end residential installations prioritizing both aesthetic minimalism and intense heating capabilities, featuring professional-grade stainless-steel construction and a large rock capacity. By separating the controls from the heater body, we ensure a more reliable and technologically advanced sauna experience, providing the penetrating heat and authentic Finnish atmosphere that Harvia is renowned for in modern wellness spaces.
