Harvia Legend 240 SL: a 21 kW stone stacked wood stove fed from outside the sauna
The Harvia Legend 240 SL is a wood-burning sauna stove with an extended firebox that fits through the wall, letting you load wood from the next room or outdoors while the open black steel frame full of stones heats the sauna. Rated at 21 kW, it heats rooms from 353 to 848 cubic feet and holds 440 pounds of stones for gentle, long-lasting heat. It is 23.6 inches wide, 30.7 inches deep, and 32.7 inches tall and weighs 181 pounds empty. The door can be hung to open left or right.
The box holds the steel frame, stove body, door, firebox extension, ash box, and manual. Sauna stones are sold separately, so add the 10 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 protective sheath, a smoke pipe cover, a floor plate, a pipe-mounted water tank, and a wood safety rail are optional. Want the fire door to double as a fireplace?

FAQ
What size sauna room can the Legend 240 SL heat?
The Legend 240 SL is a 21kW wood-burning stove rated for sauna rooms from 353 to 848 cubic feet, with a minimum room height of 72.8 inches. If your room falls outside that range, another model in Harvia’s Legend series may be a better match, and the installation manual on this page covers sizing in detail.
Can I feed the fire from outside the sauna room?
Yes. The SL extended-feed design lets you heat the sauna from another room or from outside the building, and the included fire chamber extension supports that setup. The direction of the stove door’s opening can also be changed, so the layout of your feeding side stays flexible.
Are sauna stones included with the stove?
The stove ships with its frame, body, door, ash box, and fire chamber extension; the required stones are added when you order. This heater needs a minimum of 440 lbs of stones, which is 10 boxes, so select the Required Stones option with your order on this page. Harvia also recommends one extra box so you can pick the best-fitting stones.
Does it come with a chimney?
No, a chimney is not in the box. Chimney and assembly kits, chimney extensions, smoke pipes, and a 4.5-inch Euro to 6-inch USA pipe adapter can all be added to your order on this page. The stove offers rear and upper flue connections; plan the chimney run per the installation manual and your local codes.
Can this stove heat water for the sauna?
Yes. It can be equipped with a pipe-mounted water heater: the Harvia WP250LD Legend water heater tank, which mounts on the stove pipe, is listed in the recommended add-ons on this page, so you can include it with your order and have warm water ready alongside the sauna.
What kind of firewood should I use?
The spec table calls for logs up to 15 inches long with a diameter of 3 to 5.9 inches. The fire chamber’s structure separates the combustion air and directs part of it to the upper chamber, which gives a cleaner and more efficient burn. See the installation and operation manual for full firing guidance.
How close can the stove sit to benches and walls?
Harvia notes this model has smaller-than-usual safety distances from its side and back surfaces, which gives you more freedom in placing the benches. Exact clearances are not listed on this page, so follow the installation manual and local codes; the protective sheath panel and protective bedding in the add-ons are made for shielding nearby surfaces.
