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

At its Q3 2025 investor presentation on 6 November 2025, Harvia highlighted two updates to its digital sauna platform, both introduced on 16 September 2025: 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.

“It’s smart, so actually it learns about your sauna.” Matias Järnefelt, CEO, Harvia Q3 2025 earnings call, 6 November 2025

He called the new MyHarvia smartphone app “definitely the most advanced” sauna app. Fenix is backward compatible with the installed Xenio base, meaning existing Xenio owners can upgrade the panel 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.” (Full Harvia product page: Harvia Xenio / Fenix control system.

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 is a ready-made heating profile that users can customize or replace with their own favorites.
• 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 differs 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 Xenio owners can upgrade to Fenix without replacing the heater; Harvia says the panel uses the same cable connector and can be installed without an electrician. That 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. Harvia says the app and the Fenix panel share the same interface design, and its Q3 2025 presentation lists MyHarvia 2 as the default app for future Harvia heaters and controls.
• 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.
• Tips for sauna use, installation, and maintenance. In-app educational content.
• Over-the-air updates.
• Control multiple saunas from a single interface. Spa operators, destination cabins, and multi-room residential properties can manage all their saunas from one app without separate accounts.

HUUM and EOS already had connected controls

Harvia has been talking about digital as a strategic priority since its 2018 IPO, and HUUM (with its UKU controller and app) and Harvia’s own EOS brand (whose Emo Touch 3 controller is used across EOS commercial installations) already had established connected-control offerings. Fenix and MyHarvia 2 give the Harvia brand its own, to pitch to volume dealers and consumer end users.

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. MyHarvia 2 lets one operator manage 10 or 50 saunas across a property or a chain from a single interface.

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.
