Harvia Virta 10.5kW Floor-Standing Electric Sauna Heater (240V/1PH or 208V/3PH)
The Harvia Virta 10.5kW Electric Sauna Heater is a powerful, stylish, and durable floor-standing heater designed for a premium sauna experience. Engineered for even, soft heat distribution, it creates a balanced and relaxing atmosphere, making it an excellent choice for saunas between 177 and 635 cubic feet.
Constructed with high-quality stainless steel, the Virta heater is built for long-term performance. It holds up to 154 lbs of genuine Finnish sauna stones, ensuring efficient heat retention and the ability to generate invigorating steam when water is poured over the stones. The heating elements are designed to last longer by being separated from direct stone contact, reducing wear. When maintenance is required, the entire heating element module can be quickly removed, making servicing easy and efficient.
The Virta 10.5kW pairs with the Harvia Xenio Digital Control Kit (sold separately), which allows for precise temperature control and scheduling up to 12 hours in advance. For added convenience, the Xenio control panel is WiFi-compatible, enabling remote access through the MyHarvia app.
This model is part of the Virta heater series, with additional sizes available in 6kW, 8kW and 9kW, plus the commercial Virta Pro line at 16kW and 20kW, to accommodate different sauna sizes.
