Description
The Harvia Pro 20 SS WH Sauna Stove Package is a fully complete stainless steel wood-burning sauna solution built around the powerful Pro 20 stove. This all-inclusive package comes with the Pro 20 Sauna Stove, Protective Bedding, Protective Sheath, Chimney Kit, Chimney Extension, Water Heater, Smoke Pipe, and Sauna Stones — everything you need to deliver a satisfying, steam-rich sauna bath experience for larger sauna rooms.
Designed for sauna rooms from 283 to 706 cubic feet, the Pro 20 brings serious 24kW wood-fired power with an 88-pound stone capacity and an integrated 22-liter water heater. The stainless steel chimney system and graphite black stove construction create a refined, durable installation built to last.
Wood-Burning Performance
The Pro 20 is rated at 24kW, making it one of the most powerful residential wood-burning stoves in Harvia's lineup. Built with stainless steel construction and a graphite black finish, it delivers deep, long-lasting heat suited to the largest home sauna rooms. The 22-liter water heater adds hot water convenience directly from the stove, while the 88-pound stone capacity ensures intense, satisfying löyly steam.
The stove accepts firewood up to 15 inches (39 cm) in length with a diameter of 3 to 6 inches (8–15 cm). The flue connection is located at both the top and back for flexible routing, and adjustable feet allow for level installation on sloping floors.
