Why the 20 kW Size
The Virta Pro 20 kW is rated for cabins between 353 and 1130 cubic feet, best for commercial sauna installations, boutique fitness studios, hotels, club spas, and large multi-bench cabins. For smaller installations (up to roughly 1,060 cu ft on single-phase service), step down to the Virta Pro 16 kW (240V 1-Phase). For smaller residential cabins (up to 10.5 kW), see the Harvia Virta sibling line.
Xenio CX + Fenix Upgrade, What's the Difference?
Tier 2 ("Virta Pro Heater + Control + Stones") bundles the Harvia Xenio CX45 Smart Control power unit and the matching LTY45 Power Extension Unit, required as a pair on every Virta Pro because of the heater's commercial-grade current draw. The Xenio CX45 ships with WiFi built in and connects to the MyHarvia smartphone app for remote start and scheduling.
Tier 3 ("Virta Pro Heater + Control + Stones + Fenix Upgrade") adds the Harvia Fenix FX004XW Touchscreen Display on top of the Xenio CX45, Harvia's next-generation control UI, for the longest-runway platform investment as Harvia eventually transitions from the Xenio control panel to the Fenix touchscreen across the line.
Sauna Stones
Virta Pro's tall vertical stone bed and commercial-scale kW output require a substantial volume of sauna stones to hold and release heat evenly across long, multi-session commercial usage. Every "Heater + Control + Stones" package (and the Fenix Upgrade tier) ships with the correct quantity of Harvia AC3020 sauna stones, olivine diabase, 10–15 cm size grade, 20 kg (44 lb) per box. The larger 10–15 cm grade is preferred for Virta Pro because the bigger stones pack more efficiently into the heater's vertical stone bed and they hold heat longer through repeated water throws. Stone quantity by kW: 5 boxes (16 kW), 7 boxes (20 kW).
Installation & Electrical Requirements
The Virta Pro 20 kW requires a dedicated 208V 3-Phase circuit (55.5 Amps per leg, 6 Gauge Copper) wired by a licensed electrician experienced with commercial sauna installations. Always defer to the included Harvia installation manual and your local AHJ for final wire-size and overcurrent-protection requirements. Virta Pro is UL Listed.

About the Harvia Virta Pro Family
Harvia Virta Pro is the commercial-grade big brother of the residential Virta, same brushed stainless steel housing and top-loaded vertical stone bed, scaled up for the demands of light- and full-commercial sauna installations. Available in 16 kW (240V 1-Phase, HL16U1) and 20 kW (208V 3-Phase, HL20U3) outputs, the Virta Pro is rated for sauna cabins from roughly 600 cu ft up to 1,400 cu ft, the volumes typical of boutique fitness studios, hotel spas, club lounges, and multi-bench residential builds.
Because the Virta Pro draws far more current than the standard Xenio CX45 can switch on its own, every Virta Pro install pairs the CX45 Smart Control with the matching LTY45 Power Extension Unit (a contactor box that hands off the high-current load while leaving the CX45 in charge of scheduling, WiFi/MyHarvia app control, and temperature regulation). The optional Fenix Upgrade adds Harvia's next-generation FX004XW touchscreen display on top of the Xenio CX.
For smaller residential cabins (up to 10.5 kW), see the Harvia Virta sibling line.
