The Harvia Pro 20 Duo combines traditional sauna heating with the cozy ambiance of a fireplace—offering two experiences in one. Designed to heat your sauna from an adjoining room, this innovative stove lets you enjoy a warm, steamy sauna while also creating a relaxing fireplace atmosphere in the next space.

Perfect for medium-sized saunas, the Pro 20 Duo delivers consistent heat and long-lasting performance. Its large stone capacity ensures fast, even warming and steady steam generation. The adjustable legs simplify installation, allowing you to align the chimney connection easily.

Crafted with a durable stainless steel exterior and a cast-iron glass door, the Pro 20 Duo blends functionality with elegant Nordic design. You can also equip it with an optional pipe-mounted water tank for added convenience.

Experience efficient heating, refined craftsmanship, and authentic sauna tradition—all in one versatile wood-burning heater.
