Harvia Pro 20 RS: a wood sauna stove with an 8 gallon water tank on the right
The Harvia Pro 20 RS is the Pro 20 wood stove with a fixed 30 liter (about 8 gallon) water tank on its right side, so one fire heats both the sauna and your wash water. It is rated at 24.1 kW for rooms from 283 to 706 cubic feet. It stands 30 inches tall and 23 inches wide including the tank, and weighs 144 pounds. The steel casing is graphite black with a stainless steel front, and you can see the fire through a large glass door.
The box holds the stove, the manual, and the warranty. Sauna stones are sold separately, so add the 2 boxes it needs on the page. A chimney is not included, so pick the chimney kit, any extensions, and the adapter to 6 inch US pipe on the page. A floor plate and a bucket and ladle set are optional. Want the tank on the left? Choose the Harvia Pro 20 LS stove. The Harvia Pro 20 RS ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
How does the built-in water tank work?
The Pro 20 RS carries a fixed 30-liter water tank on the right side of the stove body, so the same fire that heats your sauna warms the tank. Harvia pitches this setup as perfect for cottage settings. The tank is fixed rather than removable, so plan your layout around its right-hand position.
What size sauna room does this stove suit?
It is a 24.1kW wood stove rated for rooms from 283 to 706 cubic feet, and its large stone amount translates into hearty steam and heat across that range. If your room falls outside those figures, the Harvia Pro lineup includes other sizes; confirm room volume against the installation manual.
What is the difference between the RS and LS versions?
Tank position. On this RS model the 30-liter water tank is fixed to the right side of the stove; the LS version places it on the left. Choose whichever side keeps the tank accessible and clear of benches and door swings in your sauna’s layout, since the tank cannot be moved to the other side.
Are the sauna stones included?
The stove requires a minimum of 88 lbs of stones, and on this page they are supplied through the Required Stones add-on as two boxes of split-face stones. Select them with your order so stove and stones arrive together; the installation and operation manual covers stone placement.
Do I need to buy a chimney too?
Yes, the box holds the stove, its installation and operation manual, and warranty documents, so venting is ordered separately. The add-on selectors on this page offer chimney and assembly kits for barrel or flat roofs, 500mm and 1000mm extensions, smoke pipes, and a 4.5 inch Euro to 6 inch USA pipe adapter. Configure the flue per the manual and local codes.
What clearances does the stove need?
The specification table lists safety distances to non-combustible materials of 12 inches at the front, 4 inches at the sides and back, and 52 inches to the ceiling, with a minimum room height of 81 inches. For combustible structures and any permitted reductions, follow the installation and operation manual and your local codes.
