Harvia Launches New Fenix Full-Touch Controller and MyHarvia 2 App

At its Q3 2025 investor presentation on 6 November 2025, Harvia unveiled two major updates to its digital sauna platform: a new Fenix full-touch control panel for the volume sauna segment, and a rebuilt MyHarvia 2 mobile application. On the 6 November earnings webcast, CEO Matias Järnefelt introduced Fenix in plain language and used the occasion to claim the mobile app crown outright.

"It's smart, so actually it learns about your sauna. MyHarvia smartphone app and definitely the most advanced sauna app there." — Matias Järnefelt, CEO, Harvia Q3 2025 earnings call, 6 November 2025

Both are backward compatible with the installed Xenio base, meaning existing Harvia electric heater owners can upgrade without replacing the heater itself. Three months later, on the Q4 2025 earnings call on 12 February 2026, Järnefelt gave the product its first commercial report card: "The sales started in third quarter, and it's shown really great performance during quarter four."

Harvia Fenix: 4.3-Inch Full-Touch Screen

The new Fenix control panel is Harvia's first full-touch capacitive screen controller for the volume sauna segment (as opposed to the premium EOS Emo Touch 3 that EOS Group has offered at the high end of the market). Key features disclosed in the Q3 2025 presentation:

• 4.3-inch full-touch screen. Replaces button-and-dial controls on predecessor Xenio units with a tablet-style interface.
• Three ready-made presets: Mild, Cozy, and Hot. Each preset sets target temperature, humidity target (for combi units), and session length without user configuration.
• Customizable user profiles. Multiple household members can save their own preferred settings and switch without re-entering temperature and time.
• Smart "ready-by" timer. User specifies the time they want the sauna warm (for example, "ready at 7:00 PM") and the controller calculates heat-up time and starts the heater at the right moment. This is a genuinely different UX from the traditional timer-based controls that have dominated sauna interfaces for decades.
• Wi-Fi connectivity with over-the-air updates. Firmware updates pushed automatically; new features added without a service visit.
• Compatible with installed Xenio base. Existing Harvia heater owners can upgrade to Fenix without replacing the heater, which dramatically expands the addressable market for the controller upgrade.

MyHarvia 2: Personal Sauna Data, Multi-Sauna Control

The MyHarvia 2 app is a ground-up rebuild of the original MyHarvia platform. Feature highlights from the Q3 presentation:

• Modern and intuitive user interface. Positioned by Harvia as the default app for all future Harvia heaters and control units.
• User profiles and personal sauna data. Each user gets their own profile, with preferred temperature, session length, and historical session data.
• Statistics: track and learn from your sauna routines. Session count per week, temperature averages, duration trends. This is a meaningful step toward sauna as a quantified health practice, mirroring what fitness tracking did for exercise over the past decade.
• Tips for sauna use, installation, and maintenance. In-app educational content.
• Over-the-air updates.
• Control multiple saunas from a single interface. This is a specifically commercial-and-destination-property feature. Spa operators, destination cabins, and multi-room residential properties can manage entire sauna fleets from one app without separate accounts.

Why This Is Strategically Important

Harvia has been talking about digital as a strategic priority since its 2018 IPO, but the execution has historically lagged competitors like HUUM (whose Drop controller and app are category-leading) and EOS (whose Emo Touch 3 premium controller is used across EOS commercial installations). Fenix and MyHarvia 2 close that gap and give Harvia a credible platform story to pitch to volume dealers and consumer end users.

The commercial and destination-property angle is where this gets more interesting. Social sauna operators, ski lodge installations, apartment-complex amenity saunas, and spa chains are increasingly looking for sauna equipment that comes with operator-grade monitoring. A single-interface app that lets an operator manage 10 or 50 saunas across a property or a chain is exactly the product profile these buyers need, and Harvia now has it.

Pair With MyHarvia Sensor for Wood-Fired Data

In Q4 2025, Harvia also introduced the MyHarvia Sensor, a standalone temperature and humidity sensor that pairs with the same MyHarvia 2 app to add smart-sauna data to wood-fired or non-Harvia electric saunas. The combination means any Harvia-platform user can manage electric saunas through Fenix plus app, and wood-fired or retrofit saunas through the Sensor plus app, with both showing up in the same dashboard. This is the first commercial-grade sauna platform with coverage across electric, wood, and third-party hardware.
