Harvia KIP45W 4.5kW Sauna Heater Package Xenio Wi-Fi & Stones Included

The KIP45W's dual wall construction keeps the exterior cool to the touch at all times — a critical safety and comfort feature in smaller sauna cabins where proximity to the heater is unavoidable. Industrial-grade serviceable heating elements with direct rock-to-element contact deliver fast, even heat and consistent steam. Stainless steel construction built for decades of reliable use. The Harvia Xenio is a precise, modern flush-mount control unit with Wi-Fi connectivity for full remote management via the Harvia app — control temperature, time, lighting, and fan from anywhere inside or outside the sauna room. Pre-set sessions up to 12 hours in advance so your sauna is ready when you arrive.
