Description
The Harvia Virta HL110E 10.5kW Sauna Heater is a powerful and durable electric sauna heater designed for medium to large sauna rooms. Built with strong black steel construction, the Virta series combines reliability, modern design, and authentic Finnish sauna performance.
Designed for frequent sauna use and long sauna sessions, the Virta heater provides consistent heat and excellent heat distribution. Its large stone capacity allows the heater to produce smooth, balanced warmth and authentic Finnish löyly steam when water is poured over the heated stones.
The heater operates with a Harvia Xenio digital control system (sold separately), allowing precise temperature control and convenient sauna operation.
Harvia heaters are designed, engineered, and manufactured in Finland, the birthplace of sauna.
Heating Performance
The Harvia Virta HL110E delivers 10.5kW of heating power, making it ideal for sauna rooms ranging from 177 to 635 cubic feet.
Harvia’s advanced heating elements ensure fast warm-up times and even heat distribution, creating a comfortable sauna environment for every session.
The heater requires 150 pounds of sauna stones, which absorb heat from the elements and gradually release warmth throughout the sauna room while producing traditional löyly steam.
