Great amount of stones – wonderful sauna bath. The Harvia Legend woodburning stoves give you the ultimate sauna experience.

Part of the air is directed to the upper part of the fire chamber. This way the burning is cleaner and more efficient. This grate structure also gives the stove a longer lifespan. The smaller than usual safety distances from the side and back surfaces to burning materials enable you to locate the benches more freely. The Legend stoves can be equipped with a pipe-mounted water heater. The Harvia Legend 240 is an excellent choice for a medium sized sauna.
