The 9kw Stainless Steel Virta Combi Heater is a combined electric heater and steamer. It is powerful, stylish, and easy to use. The subtle and modern elegance of the heater provides a beautiful centerpiece for any of our larger 6-person saunas. With high reaching temperatures, a large amount of sauna stones, and controlled humidity the Virta Combi offers the highest quality traditional sauna experience. Up to 100-150lbs of genuine Finnish sauna stones are encased by sleek stainless steel. A stone cup located near the top of the heater can hold essential oils that will gradually engulf your sauna with a relaxing aroma. This heater is uniquely designed with a manual water filler at the front. This allows you to set a desired temperature and steam control for a gentler and more balanced sauna steam. For an even more intense burst of steam, sprinkle water on top of the stones using a bucket and ladle. It is also designed with a digital controller that can be mounted on the outside of the sauna and can be preset up to 12 hours in advance. The clear touch digital control panel is easily installed and allows you to set the desired temperature and humidity level.
