The Harvia M3 SL allows users to conveniently heat their sauna from another room or outside the building. You can easily change the doorâs opening direction, making these stoves more user-friendly. The SL and Boiler stoves deliver an excellent bathing experience in small and medium-sized saunas. You can connect Boiler stoves to a separate water tank for added functionality.
Harvia equips all through-the-wall heating stoves and Boiler models with a glass door to enhance the ambiance. The adjustable legs in the 20-series simplify installation, ensuring the stove remains level even on inclined floors.
