Most wood stoves are a box with rocks piled on the lid. The Cilindro is a vertical stainless steel cage packed with 264 lbs of stone from floor to top, with the firebox running up the middle. It is a floor-standing wood burning sauna stove made in Muurame, Finland, in two sizes. The Cilindro 16, part number WKPC16S, is rated 16 kW for rooms of 212 to 459 cubic feet. The Cilindro 20, part number WKPC20S, is rated 17 kW for 283 to 706 cubic feet. Both take the same stone load on the same 21.9 inch square footprint.
Heat leaves a conventional stove mostly through the top. In the Cilindro the fire is surrounded by stone on every side, so the whole column charges rather than just the crown. A rear ventilation duct pulls room air up through the cage while it burns. Water meets hot rock over a taller surface and keeps meeting it on the way down, giving longer, softer steam than a flat-topped stove of the same output.
Both take a glass hatch, so the fire is visible while it runs, and the hinges reverse so the door opens left or right to suit the room.
Size by room volume. Multiply width by depth by height in feet. The Cilindro 16 covers 212 to 459 cubic feet, the Cilindro 20 covers 283 to 706. The numbers in the model names are series designations, not outputs, which is why the Cilindro 20 is rated 17 kW. Read the kilowatt figure, not the name. The 20 also takes a longer log, 39 cm against 35 cm, and its legs adjust through 30 mm for an uneven floor.
This is a solid fuel appliance and the safety distances are not negotiable. To combustible material both models need 19.69 inches at the front, 5.91 inches at each side, 7.87 inches at the rear and 39.4 inches from the top of the stove to the ceiling. To non-combustible material the two models differ: the Cilindro 16 allows 1.97 inches at side and rear, the Cilindro 20 needs 3.94 inches. Do not read one model's figure off the other. The floor must be non-combustible and able to carry the load. A concrete slab of 60 mm or more takes the stove directly. Anything else, including a tiled floor, needs the WL120 protection base, because tile adhesive and grout are not heat resistant. An unshielded smoke pipe needs 19.69 inches to combustibles, or 9.84 inches with the WZ020130 radiation shield. Chimney work is a job for a certified installer and is usually subject to local permit.

Both models connect at 115 mm, take a flue pipe of 110 mm minimum internal diameter, and are rated to chimney temperature class T600. Maximum pipe length is 5 metres and the upper connection carries 50 kg. Confirm which connection your room needs before ordering pipe, because the parts differ.

If you want the same fire in a lower, wider body, the Harvia M3 is the classic box stove at 16.5 kW. If your room has power and you would rather not carry wood, the Harvia Virta gives a comparable stone column on electric heat.
Wood stoves go wrong at the clearances and the chimney, not at the stove. Send us your room dimensions, your wall and floor construction and where the flue can run, and we will tell you whether the Cilindro fits before you buy it. We stock the protection base, the sheath, the pipe guard and the stones alongside it. Call 866-861-6317, 9am to 6pm EST, Monday to Friday, or book a call. Financing is available at checkout. White glove delivery options available as a paid add-on.
No. It is rated 17 kW. The number in the model name is a series designation, not an output figure. The Cilindro 16 is rated 16 kW.
Both models hold 264 lbs of 10 to 15 cm stone, which is six 44 lb boxes of Harvia AC3020 split-face olivine. Rinse the dust off before stacking. Stack loosely so air can move, and stand elongated stones on end.
Not directly. The floor must be non-combustible. A concrete slab of 60 mm or more is fine as it is. A wooden or tiled floor needs the WL120 protection base.
Neither is required. The WL200PC sheath and WL300PC pipe guard are optional. Fitting the sheath cuts clearances to 50 mm at the sides and 70 mm at the rear. If you fit a guard rail, the published safety distances still apply.
No. The distributor publishes CE for both models and they are tested to EN 15821:2010. Harvia publishes no UL, ETL or CSA listing for the Cilindro wood burning range. Check what your local authority requires before you commit, because some jurisdictions ask for a North American listing on solid fuel appliances.
Either. Both are drilled for both and the unused opening takes the supplied stopper. The rear opening centres 550 mm from the floor. The top opening is 630 mm on the Cilindro 16 and 670 mm on the Cilindro 20.
