Harvia Legend 240 Duo 21kW Wood Burning Sauna Stove/Fireplace Combo | WK240LDLUX

Harvia Legend 240 21kW Duo Wood Burning Sauna Stove/Fireplace Combo | WK240LDLUX

The Harvia Legend 240 Duo is perfect for heating your sauna from outside or another room. The black steel frame shows off the abundant amount of stones that provide good heat even if the fire dies down. The grate frame also gives the stove a longer lifespan.

The Harvia Legend 240 Duo fire chamber has an innovative 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.

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.
