Type: Electric Sauna Heater
The Harvia Spirit sauna heater, inspired by earth’s natural materials, brings you closer to nature while enjoying the healing power of sauna heat. The gently curved body of the heater is designed to use rounded stones, seamlessly fusing the beauty of nature with an elegant handmade design. The rounded stones offer a soft, enveloping sauna steam to relax your body and mind, whilst the heater’s design adds a captivating touch to any sauna. Whilst rooted in nature, this heater also looks towards the future.
The fast-heating electric sauna heater can be operated using Harvia Xenio or Fenix control units and has a WiFi app so you can control the heater and all aspects of your sauna from your smart device using the MyHarvia app.
The heater has integrated safety features to prevent the heater from starting if items are placed on top of it, as well as to prevent overheating. It features a heating element and sauna stone separator/protector to elongate the lifespan of the heating elements. Harvia Spirit electric heaters are designed and manufactured in Finland and meet regulations and local requirements for electric sauna heaters in the USA.

Minimum Safety Clearances:



The Harvia Xenio is the industry standard for digital sauna control. It is perfect for users who want a straightforward, tactical interface without over-complicating their routine.
Tactile Control: Uses a clear, illuminated digital display and responsive buttons.
WiFi Ready: This package includes the WiFi upgrade, allowing you to use the MyHarvia App to preheat your sauna from your smartphone.
Compact Footprint: A small, unobtrusive panel that fits almost anywhere.
The Harvia Fenix is more than a control panel; it’s an intelligent sauna companion. It is designed for those who want a premium, "smart home" experience with zero guesswork.
AI-Adaptive Learning: The standout feature. Fenix actually learns how quickly your specific sauna room heats up. Instead of guessing, you tell Fenix when you want to step in, and it calculates the exact start time to reach your target temperature efficiently.
Immersive Touchscreen: A beautiful 4.3-inch glass interface that mirrors the look and feel of modern high-end electronics.
One-Touch Presets: Don't want to fiddle with numbers? Choose between Mild (soft, humid), Cozy (standard), or Hot (traditional Finnish) profiles at the tap of a finger.
Advanced Control: Beyond temperature, Fenix offers more nuanced management of humidity, ventilation, and lighting, all through the updated MyHarvia 2 ecosystem.
