Harvia Legend 300 Duo 23.5kW Wood Burning Sauna Stove/Fireplace Combo | 300DUO
Harvia Legend 300 Duo 23.5kW Wood Burning Sauna Stove/Fireplace Combo | 300DUO
This is the right choice for people who want to conveniently heat their sauna from another room or outside the building. The Harvia Legend wood burning heaters give you the ultimate sauna experience. The black steel frame has a mighty amount of stones inside, and as they heat up, you get a magnificent sauna bath even at a lower temperature. The large number of stones ensures good heat, even if the fire dies down in between.
The fire chamber of Legend wood burning heaters 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. This grate structure also gives the wood burning heater 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 direction of the door opening can be changed along with the adjustable legs making this wood burning heater easy to place in your sauna.
