The Harvia 50 SL is a high-quality and versatile tunnel heater designed for large saunas and for providing steam to even big groups at once. It is a through-wall heater, installed in the sauna with the firebox door extending into an adjacent room, where it functions as a fireplace—perfect for roasting sausages, for example.

The graphite black Harvia 50 SL wood-burning stove holds a massive amount of stones, ensuring even and consistent steam in spacious sauna rooms. The door hinge can be reversed according to preference. This communal stove is especially well suited for sports centers, camp facilities, and large saunas in service businesses.
