Harvia Legend 240 DUO model is the right choice for people who want to conveniently heat their sauna from another room or outside the building with nice big door. The size of the sauna room is 10-24 m3. The fire chamber of Legend stoves has a modern grate structure that separates the combustion air. Part of the air is directed to the upper part of the fire chamber. This way the burning is cleaner and more efficient.
