Harvia Pro 20 SL BIMSCHV2 Wood-Burning Sauna Stove (WKPR20SLM10)

The Pro 20 SL in its German BImSchV Stufe 2 compliant form— the emissions standard that governs solid-fuel appliances in Germany and, increasingly, in strict low-emission zones across Europe.

Same 8–20 m³ heating power and same side-loading firebox as the standard 20 SL, but with a redesigned combustion chamber and secondary air system that meets the tightened particulate and CO limits. If your local building control or planning permission specifies a BImSchV 2 stove, this is the compliant Pro 20 SL.
