Harvia 20 Pro 24kW Sauna Wood Burning Stove

The Harvia 20 Pro stove is designed for vigorous sauna bathing in medium-sized saunas. Thanks to the large stone compartment of the stove, the steam is as pleasant and hearty as you can hope for. The fire glowing behind the cast-iron-framed glass door adds to the atmosphere of the sauna. The wood-burning heater features a cast-iron glass door and an air-flow spoiler made of stainless steel. The adjustable legs make the wood-burning heater easy to place in the sauna.
