The Harvia 20SL is a versatile wood-burning sauna stove designed to offer the convenience of heating your sauna from an adjacent room or even from outside the building. This through-the-wall heating solution is perfect for those who want to maintain the sauna’s cleanliness by keeping the firewood and ash outside the sauna area. With a reversible door, you can easily change the opening direction to suit your sauna’s layout, making the Harvia 20SL a flexible option for any installation.

The stove’s sturdy construction features a sleek combination of galvanized metal in black and stainless steel, providing both durability and a modern aesthetic. The glass door enhances the sauna experience by allowing the warm glow of the fire to permeate the room, adding to the relaxing ambiance. The Harvia 20SL is designed to efficiently heat small to medium-sized saunas and can be connected to a separate water tank if desired, further extending its functionality.
