External Feed Wood Sauna Stove for a Cleaner Experience
The Harvia Legend 240 SL Wood Sauna Stove is designed for those who want a true wood-fired sauna experience with added convenience. Its external feed system allows you to heat the sauna from another room or outside the building, keeping the sauna space cleaner and more comfortable.
This unique design also enables the stove to heat two rooms at once, making it a versatile solution for advanced sauna setups.
Powerful Heating Performance
With 21kW of output, the Legend 240 SL efficiently heats sauna rooms ranging from 353 to 848 cubic feet. Its innovative combustion system ensures efficient burning, consistent heat, and long-lasting performance.
