Harvia Wood Burning Sauna Heater Model 20 for the Traditional Sauna Experience

Soft heat, soft steam and a crackling fire!

Designed to use wood in place of electricity with very effective flame circulation system. The system heats up the rocks evenly and the sauna warms up quickly. The heat is efficiently transferred to the rocks. The result is soft heat. Create a pleasant steam by sprinkling water on the rocks. These sauna heaters have an excellent efficiency ratio (more heat, less wood consumed).
