Built-In Controls vs. Harvia Xenio External Control Packages

When choosing a Harvia electric sauna heater, you’ll notice two main options: built-in controls or external controls (like the Harvia Xenio system). Each has its own advantages, depending on how you plan to use your sauna.

Built-In Controls

• Advantages:
  • Simple and straightforward: the dials are right on the heater
  • No extra installation or wiring for a separate control unit
  • Lower cost compared to external packages
• Disadvantages:
  • You have to reach the heater to turn it on, adjust temperature, or set a timer
  • Limited features: just heat and time settings
  • Not as precise in temperature control

Harvia Xenio External Controls (Wi-Fi Included)

• Advantages:
  • Wall-mounted digital panel makes it easy to control your sauna without touching the heater
  • Precise temperature and time settings
  • Extra features like delayed start and pre-heating
  • Safer and more convenient, especially if your heater is hot or hard to reach
  • Wi-Fi control comes standard: every Xenio package can connect to the MyHarvia app, letting you start, stop, and monitor your sauna right from your phone
• Disadvantages:
  • Slightly higher cost than built-in controls
  • Requires more wiring during installation

Built-in controls are great if you want something simple and budget-friendly. But if you want a smarter, more precise, and more convenient sauna experience, with full remote control from your phone, Harvia Xenio external controls are the way to go.

Understanding UL Certification Limits on Harvia Heaters

When you’re looking at sauna heaters in North America, Harvia Included, you’ll notice most of them come with UL certification. UL stands for Underwriters Laboratories, an independent safety testing organization. Basically, UL makes sure that electrical products, including sauna heaters, meet certain safety standards before they’re sold.

For sauna heaters, UL certification comes with a couple of important limits:

1-Hour Maximum Run Time: UL-approved heaters are designed with a built-in safety feature that limits operation to a maximum of one hour per cycle. After reaching this limit, the heater will automatically shut off and remain off until it cools to a safe temperature. This prevents overheating and reduces the risk of accidental misuse.

194°F (90°C) Maximum Temperature: UL-certified heaters are not allowed to heat the sauna above 194°F. This might sound low if you’re used to traditional European saunas, where temperatures often climb higher. But in North America, the UL limit is there to reduce risks and ensure safe operation.

If you’re shopping for a sauna heater, you’ll want to keep these limits in mind. For most users, 194°F still feels very hot, especially once you create steam by pouring water on the stones. The one-hour timer is usually enough for a full sauna session, but it can feel limiting if you’re used to longer runs or higher heat.

Where do I go from here?
