The Harvia Pro 20 ES is a Harvia wood-burning sauna stove rated 24.1 kW for rooms of about 283–706 cu ft. Made in Finland. This ES version includes a water tank on the stove for heating wash water — not a steam generator. You burn wood, heat the stones, and throw water for löyly — no electric heater circuit for the stove itself.
How it heats
Load firewood in the firebox. The stove body and the stones store heat; ladle water onto the rocks for steam. Connect to a proper chimney with the clearances in the Harvia wood-stove manual. Standard models load from inside the sauna. Chimney kits are sold separately unless a WH package on this site names one.

FAQ
Are stones included? Not on the stove-only listing. Packages: only if our team confirms stones are in that carton.
Does it need 240V? No. It burns wood. You still need a legal chimney and clearances.
Indoor or outdoor? The stove sits in a sauna room. That room can be an indoor build or an outdoor cabin rated for a wood stove.
Chimney included? Only when a package clearly includes it (often the WH SKUs). Otherwise order a chimney kit.
