Harvia PRO 20 24kW Wood Burning Sauna Stove: Proven Finnish Power for Medium-Large Saunas
The Harvia PRO 20 is one of the most proven wood-burning sauna stoves Harvia makes. At 24kW it heats sauna rooms up to 700 cubic feet — a full step up from the M3. Heavy stone load, glass door, and reliable Harvia combustion engineering. The PRO 20 is what you choose when the M3 is undersized and you want a battle-tested Finnish wood stove.
Why Buy From RecovAthlete
We're an authorized Harvia dealer — not a marketplace reseller. Your warranty is valid and your order is fulfilled correctly. We confirm your chimney kit for your specific ceiling height before your order ships, so you don't receive the wrong flue components on installation day.
Questions about sizing, clearances, or installation? Call 866-861-6317 and you'll reach someone who has configured dozens of these setups.
“Harvia is the world's leading sauna heater manufacturer. Every stove here is a genuine OEM Harvia product, confirmed before it ships.”
Saunas from 460 to 700 cubic feet where the M3 is too small and serious reliable wood-burning heat is required.
Family saunas and dedicated home sauna rooms that see regular use from 3-6 people.
Not ideal for: Saunas over 700 cu ft (see PRO 36) or buyers needing exterior loading (see PRO 20 SL).
What You’re Actually Getting
- 24kW High-Output Combustion — Heats a 700 cu ft sauna comfortably even in cold climates.
- Heavy Stone Load — More stones than the M3 — richer, more sustained löyly steam per pour.
- Glass Door — Tempered glass door with full fire view.
- Complete Kit Available — PRO 20 complete kit with chimney system available at RecovAthlete.
- Six Variants Available — Standard, SL exterior, DUO fireplace, ES/RS/LS water tank versions — one for every installation situation.

Installation Notes
This stove requires a chimney system running through the wall or ceiling of your sauna room. Most installations use the Harvia chimney kit — WHP1500 (stainless) or WHP1500M (black) — which is built for the standard 4.5 inches (115 mm) flue. For higher ceilings, add extension pipes WHP500 (1.64 ft) or WHP1000 (3.3 ft). A protective sheath is required if the stove is within minimum clearance distance of combustible walls. We confirm the correct chimney kit for your ceiling height before your order ships. Call 866-861-6317 for pre-installation documentation for your contractor.
On the investment: A wood-burning sauna stove built to Harvia's quality standard should last 20–30 years under regular use. Spread across years of daily sessions, the cost per use is much lower than most buyers expect. This is not a piece of equipment you replace on a schedule — it’s one you pass on.
