Wood burning heater Harvia Pro 20 Duo Steel

The Harvia 20 Duo wood burning heater is a unique 2-in-1 solution that combines a wood burning heater and a fireplace. Heating up the stove lets you enjoy the atmosphere in two rooms. Heat up your sauna to bathing temperature ‒ and enjoy the pleasant atmosphere of the fireplace at the same time. The wood burning heater creates a traditional sauna atmosphere and gives off great steam. After the sauna, you can enjoy the afterheat in the fireplace room, cook sausages and enjoy refreshments… and then hit the sauna again. Style is also one of Duo’s strengths: the outer casing is made of high-quality stainless steel, the wood burning heater features an impressive and robust glass door and the wood burning heater technology is created by the world’s largest sauna wood burning heater manufacturer.
