Frequently Asked Questions
What is the difference between the Virta Combi and a standard electric sauna heater?
A standard electric sauna heater produces dry heat only. The Virta Combi HL110SA includes an integrated steamer with a 5-litre water reservoir, enabling steam sauna, herbal sauna, and fragrance sauna modes in addition to traditional dry heat. This makes it a more versatile option for users who want multiple session types from a single unit.
What size sauna room is the HL110SA designed for?
The HL110SA is rated for sauna rooms between 177 and 635 adjusted cubic feet. The adjusted cubic footage accounts for room construction materials and insulation. Its wide range makes it suitable for both smaller home saunas and larger residential or light commercial installations.
What is the difference between the 240V 1PH and 208V 3PH variants?
The 240V single-phase variant is suited for standard residential electrical service and requires two dedicated circuits. The 208V three-phase variant is designed for commercial facilities with three-phase electrical systems. Both deliver 10.5 kW of output. Confirm your electrical service type with a licensed electrician before ordering.
Does the HL110SA include a controller?
No. The HL110SA requires the Harvia Xenio CX30C digital controller with WiFi, which is sold separately. The controller manages temperature, steam level, session mode, and timing, and can be operated remotely via the Harvia app. The heater is not designed for use without a compatible controller.
Are sauna stones included?
Sauna stones are not included. The HL110SA requires 150 lbs (4 boxes, item AC3020) of sauna-rated stones, available separately. Only use stones specifically rated for sauna use — do not use river rocks or unrated stones.
How does the integrated steamer work?
The HL110SA includes a built-in 5-litre water reservoir that feeds water directly to the heating elements to generate steam. The reservoir supports both automatic and manual filling. Steam output and session mode are controlled via the compatible Xenio CX30C controller.
