Harvia Legend 240 SL

Legend Series 21kW Wood Sauna Stove w/Ext. Feed

If you want to heat your sauna from another room or outside the building than this Harvia Legend 240 SL is for you. With the innovative structure that separates the combustion air and directs part of the air to the upper part of the fire chamber will give you a cleaner and more efficient way of burning. The large amount of stones integrated with the modern black steel grate structure gives this wood burning heater a longer lifespan. 

This Harvia Legend 240 SL has multiple features that put this wood burning heater above the others. The opening direction of the door can be changed and the adjustable legs can give you added height. This heater has smaller than usual safety distances from the side and back surfaces to burning materials which allows you flexibility to place the benches freely. It can be equipped with a pipe-mounted water heater.
